Company Description

Wright Medical Group, Inc., through Wright Medical Technology, Inc. and other operating subsidiaries, is a global orthopaedic medical device company specializing in the design, manufacture and marketing of reconstructive joint devices and biologics products. Reconstructive joint devices are used to replace knee, hip and other joints that have deteriorated through disease or injury. Biologics are used to replace damaged or diseased bone, to stimulate bone growth, and to provide other biological solutions for surgeons and their patients. Within these markets, we focus on the higher-growth sectors of the orthopaedic industry, such as advanced bearing surfaces, modular necks and bone conserving implants within the hip market, as well as on the integration of our biologics products into reconstructive joint procedures and other orthopaedic applications.

For the year ended December 31, 2006, we had net sales of $338.9 million and net income of $14.4 million. As of December 31, 2006, we had total assets of $409.4 million. Detailed information on our net sales by product line and our net sales, operating income and long-lived assets by geographic region can be found in Note 15 to the consolidated financial statements contained in “Financial Statements and Supplementary Data.”

History

We were incorporated in November 1999, as a Delaware corporation and had no operations until December 1999 when we acquired majority ownership of our predecessor company, Wright Medical Technology, Inc., in a recapitalization transaction, and immediately thereafter acquired Cremascoli Ortho Holding, S.A., based in Toulon, France. The Cremascoli acquisition extended our product offerings, enhanced our product development capabilities, and expanded our European presence. As a result of combining Cremascoli’s strength in hip reconstruction with the predecessor company’s historical expertise in knee reconstruction and biologics, we offer a broad range of reconstructive joint devices and biologics to orthopaedic surgeons in over 60 countries.

In 2001, we sold 7,500,000 shares of common stock in our initial public offering, which generated $84.8 million in net proceeds. In 2002, we sold 3,450,000 shares of common stock in a secondary offering which generated $49.5 million in net proceeds.

Orthopaedic Industry

It is estimated that the worldwide orthopaedic industry generated sales of approximately $25 billion in 2006. We believe this figure will grow by approximately 10% annually over the next three years. Seven multinational companies currently dominate the orthopaedic industry, each with approximately $1.7 billion or more in annual sales. The size of these companies often leads them to concentrate their marketing and research and development efforts on products that they believe will have a relatively high minimum threshold level of sales. As a result, there is an opportunity for a mid-sized orthopaedic company, such as us, to focus on smaller, higher-growth sectors of the orthopaedic market, while still offering a comprehensive product line to address the needs of its customers.

Orthopaedic devices are commonly divided into several primary sectors corresponding to the major subspecialties within the orthopaedic field: reconstruction, trauma, arthroscopy, spine and biologics. We specialize in reconstructive joint devices and biologics products.

Reconstructive Joint Device Market

Most reconstructive joint devices are used to replace or repair joints that have deteriorated as a result of disease or injury. Despite the availability of non-surgical treatment alternatives such as oral medications, injections and joint fluid supplementation of the knee, severe cases of disease or injury often require reconstructive joint surgery. Reconstructive joint surgery involves the modification of the bone area surrounding the affected joint and the insertion of one or more manufactured components, and may also involve the use of bone cement.

The reconstructive joint device market is generally divided into the areas of knees, hips and extremities. It is estimated that the worldwide reconstructive joint device market had sales of approximately $9 billion in 2006, with hip reconstruction and knee reconstruction representing two of the largest sectors.

Knee Reconstruction. The knee joint involves the surfaces of three distinct bones: the lower end of the femur, the upper end of the tibia or shin bone, and the patella or kneecap. Cartilage on any of these surfaces can be damaged due to disease or injury, leading to pain and inflammation requiring knee reconstruction. Knee reconstruction was the largest sector of the reconstructive joint device market in 2006, with estimated sales of approximately $4.9 billion worldwide.

Major trends in knee reconstruction include the use of alternative surface materials to extend the implant’s life and increase conservation of the patient’s bone to minimize surgical trauma and accelerate recovery. Another significant trend in the knee reconstruction industry is the use of more technologically advanced knees, called advanced kinematic knees, which more closely resemble natural joint movement. Additionally, we believe that minimally invasive knee procedures, such as those for unicompartmental repair, which replaces only one femoral condyle, as well as minimally invasive surgical techniques and instrumentation are becoming more widely accepted.

Hip Reconstruction. The hip joint is a ball-and-socket joint which enables the wide range of motion that the hip performs in daily life. The hip joint is most commonly replaced due to degeneration of the cartilage between the head of the femur (the ball) and the acetabulum or hollow portion of the pelvis (the socket). This degeneration causes pain, stiffness and a reduction in hip mobility. It is estimated that the worldwide hip reconstruction market had sales of approximately $4.2 billion in 2006.

Similar to the knee reconstruction market, major trends in hip replacement procedures and implants are to extend implant life and to preserve bone stock for possible future procedures. New products have been developed that incorporate advances in bearing surfaces from the traditional polyethylene surface. These alternative bearing surfaces include metal-on-metal, cross-linked polyethylene and ceramic-on-ceramic combinations, which exhibit improved wear characteristics and lead to longer implant life. In addition to advances in bearing surfaces, implants that preserve more natural bone have been developed in order to minimize surgical trauma and recovery time for patients. These implants, known as bone-conserving implants, leave more of the hip bones intact, which is beneficial given the likelihood of future revision replacement procedures as the average patient’s lifetime increases. Bone-conserving procedures are intended to enable patients to delay their first total hip procedure and may significantly increase the time from the first procedure to the time when a revision replacement implant is required.

Extremity Reconstruction. Extremity reconstruction involves implanting devices to replace or reconstruct injured or diseased joints such as the finger, toe, wrist, elbow, foot, ankle and shoulder. It is estimated that the extremity reconstruction market had sales of approximately $450 million worldwide in 2006. Major trends in extremity reconstruction include unique distal radius (wrist) and foot and ankle fixation devices.

Biologics Market

The biologics market is one of the fastest growing sectors of the orthopaedic market. Biologics products use both biological tissue-based and synthetic materials to regenerate damaged or diseased bone and to repair damaged tissue. These products stimulate the body’s natural regenerative capabilities to minimize or delay the need for invasive implant surgery, replace damaged or diseased bone, and provide other biological solutions for surgeons and their patients.

Biologics products are used in spinal fusions, trauma fractures, joint replacements, and cranio-maxillofacial procedures and represent an alternative solution to autograft, a procedure that involves harvesting a patient’s own bone or soft tissue. Currently, there are three main types of biological bone grafting products, which are osteoconductive, osteoinductive and combined osteoconductive/osteoinductive that refer to the way in which the materials affect bone growth. Osteoconductive materials serve as a scaffold that supports the formation of bone but do not trigger new bone growth, whereas osteoinductive materials induce bone growth. Other biologics products enable the repair of soft tissue. These products provide favorable microenvironments for quick revascularization and cell proliferation. It is estimated that the biologics market generated sales of approximately $1.3 billion worldwide in 2006.

Government Regulation

United States

Our products are strictly regulated by the United States Food and Drug Administration (FDA) under the Food, Drug, and Cosmetic Act (FDC Act). Some of our products are also regulated by state agencies. FDA regulations and the requirements of the FDC Act affect the pre-clinical and clinical testing, design, manufacture, safety, efficacy, labeling, storage, recordkeeping, advertising and promotion of our medical device products. Our tissue-based products are subject to FDA regulations, the National Organ Transplant Act (NOTA), accreditation from the American Association of Tissue Banks (AATB) and various state agency regulations.

Generally, before we can market a new medical device, marketing clearance from the FDA must be obtained through either a premarket notification under Section 510(k) of the FDC Act or the approval of a premarket approval (PMA) application. The FDA typically grants a 510(k) clearance if the applicant can establish that the device is substantially equivalent to a predicate device. It generally takes three months from the date of a 510(k) submission to obtain clearance, but it may take longer, particularly if a clinical trial is required. The FDA may find that a 510(k) is not appropriate or that substantial equivalence has not been shown and, as a result, will require a PMA application.

PMA applications must be supported by valid scientific evidence to demonstrate the safety and effectiveness of the device, typically including the results of human clinical trials, bench tests and laboratory and animal studies. The PMA application must also contain a complete description of the device and its components, and a detailed description of the methods, facilities and controls used to manufacture the device. In addition, the submission must include the proposed labeling and any training materials. The PMA application process can be expensive and generally takes significantly longer than the 510(k) process. Additionally, the FDA may never approve the PMA application. As part of the PMA application review process, the FDA generally will conduct an inspection of the manufacturer’s facilities to ensure compliance with applicable quality system regulatory requirements, which include quality control testing, control documentation and other quality assurance procedures.

If human clinical trials of a medical device are required and the device presents a significant risk, the sponsor of the trial must file an investigational device exemption (IDE) application prior to commencing human clinical trials. The IDE application must be supported by data, typically including the results of animal and/or laboratory testing. If the IDE application is approved by the FDA and one or more institutional review boards (IRBs), human clinical trials may begin at a specific number of investigational sites with a specific number of patients, as approved by the FDA. If the device presents a nonsignificant risk to the patient, a sponsor may begin the clinical trial after obtaining approval for the trial by one or more IRBs without separate approval from the FDA. Submission of an IDE does not give assurance that the FDA will approve the IDE and, if it is approved, there can be no assurance the FDA will determine that the data derived from the trials support the safety and effectiveness of the device or warrant the continuation of clinical trials. An IDE supplement must be submitted to and approved by the FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness, study indication or the rights, safety or welfare of human subjects. The trial must also comply with the FDA’s IDE regulations and informed consent must be obtained from each subject.

If the FDA believes we are not in compliance with the law, it can institute proceedings to detain or seize products, issue a market withdrawal, enjoin future violations and seek civil and criminal penalties against us and our officers and employees. If we fail to comply with these regulatory requirements, our business, financial condition and results of operations could be harmed.

Most of our products are approved through the 510(k) premarket notification process. We have conducted clinical trials to support many of our regulatory approvals. Regulations regarding the manufacture and sale of our products are subject to change. We cannot predict the effect, if any, that these changes might have on our business, financial condition and results of operations. In particular, the FDA has statutory authority to regulate allograft-based products, processing and materials. The FDA has been working to establish a more comprehensive regulatory framework for allograft-based products, which are principally derived from human cadaveric tissue. The framework developed by the FDA establishes criteria for determining whether a particular human tissue-based product will be classified as human tissue, a medical device or a biologic drug requiring premarket clearance or approval. All tissue-based products are subject to extensive FDA regulation, including a requirement that ensures that diseases are not transmitted to tissue recipients. The FDA has also proposed extensive additional regulations that would govern the processing and distribution of all allograft products. Consent to use the donor’s tissue must also be obtained. If a tissue-based product is considered human tissue, it does not require FDA clearance or approval before being marketed. If it is considered a medical device, or a biologic drug, then FDA clearance or approval may be required.

In addition to granting approvals for our products, the FDA and international regulatory authorities periodically inspect us for compliance with regulatory requirements that apply to medical devices marketed in the U.S. and internationally. These requirements include labeling regulations, manufacturing regulations, quality system regulations, regulations governing unapproved or off-label uses, and medical device regulations. Medical device regulations require a manufacturer to report to the FDA serious adverse events or certain types of malfunctions involving its products. The FDA periodically inspects device and drug manufacturing facilities in the U.S. in order to assure compliance with applicable quality system regulations.

International

We obtain required regulatory approvals and comply with extensive regulations governing product safety, quality, manufacturing and reimbursement processes in order to market our products in all major foreign markets. These regulations vary significantly from country to country and with respect to the nature of the particular medical device. The time required to obtain these foreign approvals to market our products may be longer or shorter than that required in the U.S., and requirements for such approval may differ from FDA requirements.

All of our products sold internationally are subject to certain foreign regulatory approvals. In order to market our product devices in the member countries of the European Union (EU), we are required to comply with the Medical Devices Directives and obtain CE mark certification. CE mark certification is the European symbol of adherence to quality assurance standards and compliance with applicable European Medical Devices Directives. Under the Medical Devices Directives, all medical devices including active implants must qualify for CE marking. We also are required to comply with other foreign regulations, such as obtaining MHLW (Ministry of Health Labor and Welfare) approval in Japan, HPB (Health Protection Branch) approval in Canada, and TGA (Therapeutic Goods Administration) approval in Australia as a few examples.

Products

We operate as one reportable segment, offering products in four primary market sectors: knee reconstruction, hip reconstruction, extremity reconstruction, and biologics. Sales in each of these markets represent greater than 10% of our consolidated revenue. Detailed information on our net sales by product line can be found in Note 15 to the consolidated financial statements contained in “Financial Statements and Supplementary Data.”

Knee Reconstruction

Our knee reconstruction product portfolio strategically positions us in the areas of total knee reconstruction, revision replacement implants and limb preservation products. These products provide the surgeon with a continuum of treatment options for improving patient care. We differentiate our products through innovative design features that reproduce movement and stability, resulting in products that more closely resemble a healthy knee. Additionally, we provide a broad array of both open surgery and minimally invasive surgery (MIS) surgical instrumentation to

accommodate surgeon and patient preference. (MIS) or least invasive surgery has gained momentum in recent history due to the smaller incision and minimal disruption of soft tissues, which can significantly reduce recovery times. Faster recovery and rehabilitation times are important to the growing market of younger, more active patients who want a quick return to their active lifestyles. The MIS surgical instrumentation is not only tissue sparing but more accurate and can perform traditional/open surgery procedures as well. This is important for surgeons because not every patient clinically qualifies for the MIS surgical technique and they can standardize with one set of instruments regardless of open surgery or MIS surgical technique. Additionally, due to the difficulties of cementing techniques in small incisions, cementless implants have also gained momentum in MIS. We are utilizing our cementless implant history and expertise to provide surgical solutions for this growing opportunity. Recently, certain industry participants have heightened their focus on providing knee product offerings that offer better size-specificity to patients, with the intent of improving patient outcomes longer-term as a result of improved implant fit. We intend to expand the number of sizing options for our primary knee product line during 2007 as part of a stature-specific approach to patient treatment.

The ADVANCE ® Knee System is our primary knee product line offering. There are several innovative product offerings within the ADVANCE ® Knee System product line, one of which is the ADVANCE ® Medial Pivot Knee. The understanding of knee movement and function has advanced significantly over the past several years, and we believe the ADVANCE ® Medial Pivot Knee is the first knee to be mass marketed that takes full advantage of the strides made in understanding the knee joint. The ADVANCE ® Medial Pivot Knee is designed to approximate the movement and function of a healthy knee by using a unique spherical medial feature. Overall, we believe the ADVANCE ® Medial Pivot Knee more closely approximates natural knee motion, improves clinical performance and provides excellent range of motion.

Our ADVANCE ® Double-High Knee Tibial Insert is designed to address the needs of surgeons who desire to retain the posterior cruciate ligament (PCL) and maintain medial-pivoting kinematics. The insert design addresses an adverse phenomenon, known as paradoxical motion, that often occurs with other PCL retaining knee systems. In general, total knee systems are designed to be used either with or without the patient’s PCL. Most knee implant designs used with the PCL are based on the theory that the ligament will provide stability and increased flexion. Due to the phenomenon of paradoxical motion, however, small amounts of uncontrolled sliding can occur between the replaced femoral and tibial surfaces. This movement prevents the prosthetic knee from flexing in a stable, consistent manner like a normal knee and can result in abnormal gait and reduced flexion. The ADVANCE ® Double-High Knee component, like the ADVANCE ® Medial-Pivot, is designed to prevent paradoxical motion through medial-pivoting articulation designed to provide stability and maximize PCL function.

Our REPIPHYSIS ® Technology product grows with growing children without an operation. The non-invasive expansion can be utilized for any long bone where lengthening is needed. This technology, which we exclusively license, can be incorporated into a prosthetic implant and subsequently adjusted non-invasively when lengthening of the implant is needed. The most common application of this breakthrough technology is in the field of pediatric oncology, where growing children can have the bones attached to their hip or knee implant lengthened non-invasively, thus eliminating the need for more frequent surgeries and anesthesia.

Hip Reconstruction

We offer a comprehensive line of products for hip joint reconstruction. This product portfolio provides offerings in the areas of bone-conserving implants, total hip reconstruction, revision replacement implants and limb preservation. Additionally, our hip products offer a combination of unique, innovative modular designs, a complete portfolio of advanced surface bearing materials, including ceramic-on-ceramic and metal-on-metal articulations, and innovative technology in surface replacement implants. We are therefore able to offer surgeons and their patients a full continuum of treatment options.

The CONSERVE ® family of products incorporates anatomically-replicating large diameter bearings, led recently by the A-CLASS ® advanced metal technology. This new patent-pending metal-on-metal articulation has undergone extensive laboratory tests which suggest that over the life of the implant, this advanced surface technology will result in significantly less wear than traditional metal-on-metal hip implants. This new innovation is coupled with our BFH ® technology, which has demonstrated low rates of post-operative hip dislocation.

We continue to invest in pioneering approaches to tissue sparing hip replacement. The PATH ® MIS technique offers patients quicker recovery due to a decrease of intraoperative soft tissue trauma. The decreased soft tissue trauma results in less pain and blood loss for the patient, as well as a lower risk of dislocation.

The PROFEMUR ® patented modular neck systems allow surgeons to carefully adjust and fine-tune implant positioning during surgery. If a surgeon requires a change in leg length, offset or version, the PROFEMUR ® system conveniently allows these options, without compromise. All of these options can be changed after the hip stem is in place. Our principal PROFEMUR ® stem offerings which allow this innovative modularity include our PROFEMUR ® Z, PROFEMUR ® Plasma Z, PROFEMUR ® LX, PROFEMUR ® Tapered, PROFEMUR ® RAZ, PROFEMUR ® TL and the PROFEMUR ® RENAISSANCE ® stems. These stems represent the vast majority of popular stem designs in the current marketplace.

The DYNASTY™ Acetabular System offers surgeons the benefit of our BFH ® technology both in metal-on-metal and metal-on-cross-linked poly options with the added benefit of screw fixation. Screw fixation of sockets is sometimes needed in the case of poor bone quality. The DYNASTY™ system is based on the long track record of the LINEAGE ® Acetabular System, which offers ceramic, metal and cross-linked poly bearings.

Lastly, the GUARDIAN ® Limb Salvage System offers options for patients with significant bone loss due to cancer, trauma or previous surgical procedures. This modular system, with an array of options in a multitude of sizes and complete inter-changeability, provides the surgeon with the ability to meet a variety of patient needs. The GUARDIAN ® Proximal Tibial Implant was developed for patients with significant bone loss in the tibial bone. The GUARDIAN ® Revision Hinge Implant, another of the products offered within the system, was developed for use in revision surgeries where both bone loss and ligament deficiencies are present. The GUARDIAN ® Total Femur is used in rare cases where the entire femur must be replaced.

Extremity Reconstruction

We offer extremity products for the hand, wrist, elbow, shoulder, foot and ankle in a number of markets worldwide. Our extremity implants have many years of successful clinical history. We believe we are one of the recognized leaders in radial head repair and finger and toe implants and minimally invasive wrist fracture fixation.

Our EVOLVE ® Modular Radial Head Replacement Prosthesis addresses the need for modularity in this anatomically highly-variable joint, and is the market leading radial head prosthesis. The EVOLVE ® Modular Radial Head device provides 150 different combinations of heads and stems allowing the surgeon to choose implant heads and stems to accommodate the unpredictable anatomy of each patient. The smooth stem design allows for rotational motion at the implant/bone interface and radiocapitellar articulation, potentially reducing capitellar wear. In the first quarter of 2005, we released our EVOLVE ® Radial Head Plating System for surgeons who wish to repair rather than replace the damaged radial head. With prosthesis and plating, we believe we have become the vendor of choice for repair of radial head fractures. Further strengthening our position in the radial head market, in the first quarter of 2007, we introduced our EVOLVE ® Proline System, which adds additional size offerings and in-situ locking of the implant, a favorable feature for surgeons treating patients with intact elbow ligaments.

Our CHARLOTTE™ Foot and Ankle System is a comprehensive offering of fixation products for foot and ankle surgery, and includes six products that feature advanced design elements for simplicity, versatility and high performance. The CHARLOTTE™ Foot and Ankle System offers a complete range of options for the most common foot and ankle surgical needs. Adding to the CHARLOTTE™ portfolio, in the third quarter of 2006, we introduced the first ever locking compressing plate designed for corrective foot surgeries. The CLAW™ plate allows surgeons to dial in the length of screw and amount of compression to the fusion site, a strong advantage over traditional staples.

The LOCON-T ® and LOCON-VLS ® Distal Radius Plating Systems provide surgeons with anatomically designed, stainless steel plates used in the repair of distal radial fractures. In designing both plating systems, we utilized thin, high-strength stainless steel with low profile screws, which have been demonstrated clinically to lessen potential for

tendon irritation and/or rupture, which are complications that historically have resulted from this type of surgical repair.

Our MICRONAIL ® intramedullary wrist fracture repair system is a next-generation, MIS treatment for distal radius fractures that provides immediate fracture stabilization with minimal soft tissue disruption. The result is rapid recovery of hand and wrist functions. Also, as the product is implanted within the bone, it has no profile, thereby removing the potential for tendon irritation or rupture.

The ORTHOSPHERE ® Carpometacarpal Implant for the repair of the basal thumb joint is constructed from implant-grade ceramic, which reduces wear and increases biocompatibility compared to other implant materials. By providing an alternative to the harvesting of the patient’s own soft tissues as a spacer for the repaired carpometacarpal joint, the ORTHOSPHERE ® Carpometacarpal Implant reduces morbidity and operating time in appropriately selected patients. We have received FDA 510(k) clearance to also market this device in foot and ankle procedures such as the tarso-metatarsal joint.

Biologics

We offer a broad line of biologics products that are used to replace and repair damaged or diseased bone, tendons and soft tissues, and other biological solutions for surgeons and their patients. These products focus on biological musculoskeletal repair by utilizing synthetic and human tissue-based materials. Internationally, we offer bone graft products incorporating antibiotic delivery and anti-adhesion products.

GRAFTJACKET ® is a soft tissue graft designed for augmentation of tendon and ligament repairs such as those of the rotator cuff (shoulder) and Achilles tendon in the ankle. By augmenting the strength of the tendon repair and incorporating biologically, GRAFTJACKET ® Regenerative Tissue Matrix increases surgeons’ confidence in the surgical outcome. GRAFTJACKET ® Maxforce Extreme is a high strength form of GRAFTJACKET ® Matrix, which provides maximum suture holding power for the most challenging of tendon and ligament repairs.

GRAFTJACKET ® Ulcer Repair Matrix is designed to repair challenging diabetic ulcers of the foot, the primary cause of hospital admissions for all individuals with diabetes. More than two-thirds of the amputations administered each year are performed on individuals with diabetes, often because of difficulties associated with diabetic foot ulcers. GRAFTJACKET ® Ulcer Repair Matrix appears to be the first chronic wound graft to demonstrate the ability to reliably repair deep foot wounds, which have a much higher risk of leading to amputation. Unlike other diabetic foot ulcer products, GRAFTJACKET ® Ulcer Repair Matrix generally requires only one application to treat the foot ulcer, reducing the time and cost of treatment.

Our OSTEOSET ® bone graft substitute is a synthetic bone graft substitute made of surgical grade calcium sulfate. OSTEOSET ® bone graft provides an attractive alternative to autograft, because it facilitates bone regeneration without requiring a painful, secondary bone-harvesting procedure. Additionally, being purely synthetic, OSTEOSET ® pellets are cleared for use in infected sites, an advantage over tissue-based material. The human body resorbs the OSTEOSET ® material at a rate close to the rate that new bone grows. We offer surgeons the option of custom-molding their own beads in the operating room using the OSTEOSET ® Resorbable Bead Kit, which is available in mixable powder form. OSTEOSET ® 2 DBM graft is a unique bone graft substitute incorporating demineralized bone matrix (DBM) into OSTEOSET ® surgical-grade calcium sulfate pellets. These two bone graft materials, each with a long clinical history, provide an ideal combination of osteoinduction and osteoconduction for guided bone regeneration. Our surgical grade calcium sulfate is manufactured using proprietary processes that consistently produce a high quality product. Our OSTEOSET ® T medicated pellets, which contain tobramycin, are currently one of the few resorbable bone void fillers available in international markets for the prevention and treatment of osteomyelitis, an acute or chronic infection of the bone.

ALLOMATRIX ® Injectable Putty combines a high content of DBM with our proprietary surgical grade calcium sulfate carrier. The combination provides an injectable putty with the osteoinductive properties of DBM as well as exceptional handling qualities. This product has been well received by surgeons. Another combination we offer is ALLOMATRIX ® C bone graft putty, which includes the addition of cancellous bone granules. The addition of the bone granules increases the stiffness of the material and thereby improves handling characteristics, increases

osteoconductivity scaffold, and provides more structural support. Our ALLOMATRIX ® Custom bone graft putty allows surgeons to customize the amount of bone granules to add to the putty based on its surgical application. Most recently, we introduced ALLOMATRIX ® DR Graft, which is ALLOMATRIX ® putty that has been optimized for application in smaller fractures due to the smaller particle size of its cancellous bone granules and the application-specific volume in which it is marketed.

MIIG ® 115 Minimally Invasive Injectable Graft is an injectable form of our surgical grade calcium sulfate paste that hardens in the body. MIIG ® 115 graft combines the operative flexibility of an injectable substance with the clinically proven osteoconductive properties of our OSTEOSET ® material. MIIG ® 115 graft is ideally suited for use in non-loaded traumatic fractures such as the distal radius and tibial plateau.

MIIG ® X3 High Strength Injectable Graft is an addition to the family of MIIG ® products for the minimally invasive treatment of bone defects. It is an injectable calcium sulfate that hardens after placement, provides intraoperative support and resorbs over time as it is replaced by new bone. Compared to the MIIG ® 115 graft, the principle advantages of the MIIG ® X3 graft is that it has 2.6 times greater compressive strength, easier injectability, and a longer working time. MIIG ® X3 graft has several competitive advantages over injectable calcium phosphate products on the market, including its ability to be drilled or tapped for the placement of final hardware. Additionally, it poses less risk of damage to the joint cartilage upon extravasation (i.e., leakage into the joint space).

MIIG ® X3 HiVisc Graft is an advanced formulation of MIIG ® X3 graft specially designed for management of complex compression fractures. The modified viscosity and extended working time of MIIG ® X3 HiVisc Graft reduces the potential for extravasation of material into joint spaces and provides greater operative flexibility to the surgeon for very challenging fractures.

PRO-DENSE™ Injectable Graft has recently become available on a limited basis in key U.S. centers. PRO-DENSE™ Injectable Graft is a composite graft of surgical grade calcium sulfate and calcium phosphate. In animal studies, this unique graft composite has demonstrated excellent bone regenerative characteristics, forming new bone that is three times stronger than the natural surrounding bone at a 13 week time point. Beyond 13 weeks, the regenerate bone gradually remodels to natural bone strength.

IGNITE Ò Power Mix is a bone repair stimulus that combines calcium sulfate, DBM and autologous bone marrow aspirate (BMA) for the treatment of problem fractures and delayed non-unions. This combination of materials provides the surgeon and patient with all three critical elements that a bone graft material can offer — an osteoconductive scaffold with both osteoinductive and osteogenic capacity through the use of DBM and BMA, respectively. The IGNITE Ò Power Mix kit also provides specially-designed instrumentation both to procure BMA and to prepare the fracture site for the grafting procedure using a minimally invasive technique. In 2006, we introduced Mini-Ignite ® for stimulating repair of challenging small bone fractures, such as those of the fifth metatarsal in the foot. We believe this product to be highly synergistic with our CHARLOTTE™ fixation product line.

CELLPLEX ® TCP Synthetic Cancellous Bone is an osteoconductive, resorbable tricalcium phosphate (TCP) provided in granular form that simulates the structure of cancellous bone. It has been engineered with a highly porous, interconnected structure to facilitate the ingrowth of new bone throughout the material. Compared to other commercially available TCP products, its benefits include a superior compressive strength and physical characteristics that more closely resemble that of natural cancellous bone. It is an excellent carrier of BMA and is packaged in the INFILTRATE ® Marrow Infusion Chamber to provide surgeons a simple option for combining BMA with the CELLPLEX ® TCP, thereby adding an osteogenic component to the synthetic graft.

In early 2007, we announced that we had signed a supply agreement with Regeneration Technologies, Inc., to develop advanced zenograft implants for use in foot and ankle surgeries. During the second quarter of 2007, we plan to launch our CANCELLO-PURE™ foot and ankle implant, which will provide foot and ankle surgeons with an off-the-shelf, sterile graft that has handling characteristics superior to allograft.

Product Development

Our research and development staff focuses on developing new products in the knee, hip and extremity reconstruction and biologics markets and on expanding our current product offerings and the markets in which they are offered. Realizing that new product offerings are a key to future success, we are committed to a strong research and development program. Research and development expenses totaled $25.6 million, $22.3 million and $18.5 million in 2006, 2005 and 2004, respectively.

We continue to collaborate with surgeon advisory panels that provide advice on market trends and assist with the development and clinical testing of our products. We believe these surgeon advisors are prominent in the field of orthopaedics. We also partner periodically with other industry participants, particularly in the biologics area, to develop new products.

In the knee, hip and extremity reconstruction areas, our research and development activities focus on expanding the continuum of products that span the life of implant patients, from early intervention, such as bone-conserving implants, to primary implants, revision replacement implants, and limb preservation implants. We continue to explore and develop advanced bearing and fixation surfaces that improve the clinical performance of reconstructive devices, including ceramic-on-ceramic and low-wear metal-on-metal surfaces. Further, we provide minimally invasive tissue sparing techniques that allow patients to quickly return to work and resume their daily activities. In 2004, we introduced the ODYSSEY ® Tissue Preserving Initiative, which is a minimally invasive surgery program for hip and knee replacement procedures. In 2006, we launched two new innovative tissue sparing hip replacement techniques, the PATH ® MIS technique, which offers patients quicker mobility and recovery after total hip replacement. The second new hip technique that we launched in 2006 was the SUPERCAP™ MIS technique, which offers patients quicker recovery due to a decrease of intraoperative soft tissue trauma. We anticipate that we will continue to focus on additional MIS techniques and instrumentation for further surgical applications including the knee.

In the biologics area, we have a variety of research and development projects underway that are designed to further expand our presence in this market. Such projects include developing materials for new biologics applications as well as the integration of biologics products into reconstructive joint procedures and other orthopaedic applications.

New products, procedures and techniques that we introduced across all product lines since 2004 include, but are not limited to, the OSTEOSET ® 2 DBM surgical-grade calcium sulfate pellets, the ADVANCE ® Double-High Knee Tibial Insert, the MICRONAIL ® intramedullary distal radius implant, the ODYSSEY ® Tissue Preserving Initiative for hip and knee procedures, the PROFEMUR ® Tapered Stem Total Hip System, the CHARLOTTE™ Foot and Ankle System, the MIIG ® HV Procedure Kit, the GRAFTJACKET ® Regenerative Tissue Matrix Maxforce Extreme, the ODYSSEY ® Minimally Invasive Knee Instrument, the CONSERVE ® Total A-CLASS ® Advanced Metal with BFH ® Technology hip system, the PROFEMUR ® RENAISSANCE ® hip stem, the CHARLOTTE™ CLAW™ Plate, the PROFEMUR ® RENAISSANCE ® Total Hip System, the ODYSSEY ® Distal Cut First instruments, and the A-CLASS ® Polyethylene Liner for the LINEAGE ® Acetabular Hip System.

Manufacturing and Supply

We operate manufacturing facilities in Arlington, Tennessee, and Toulon, France. These facilities primarily produce orthopaedic implants and some of the related surgical instrumentation used to prepare the bone surfaces and cavities during the surgical procedure. The majority of our surgical instrumentation is produced to our specifications by qualified subcontractors who serve medical device companies.

During the past year, we have continued to modernize both production facilities through changes to the physical appearance and layout, and additions of new production and quality control equipment to meet the evolving needs of our product specifications and designs. In seeking to optimize our manufacturing operations, we have adopted many sophisticated manufacturing practices, such as lean manufacturing and Six Sigma quality programs, which are designed to lower lead times, minimize waste and reduce inventory. We have a wide breadth of manufacturing capabilities at both facilities, including skilled manufacturing personnel.

We rely on a limited number of suppliers for the components used in our products. Our reconstructive joint devices are produced from various surgical grades of titanium, cobalt chrome, stainless steel, various grades of high density polyethylenes, silicone elastomer and ceramics. We rely on one source to supply us with a certain grade of cobalt chrome alloy and one supplier for the silicone elastomer used in our extremity products. We are aware of only two suppliers of silicone elastomer to the medical device industry for permanent implant usage. Additionally, we rely on one supplier of ceramics for use in our hip products. In addition, for certain biologics products, we depend on one supplier of DBM and cancellous bone matrix (CBM). Further, we rely on one supplier for our GRAFTJACKET ® family of soft tissue repair and graft containment products and one supplier for our ADCON ® Gel products. We maintain adequate stock from these sold suppliers in order to meet production requirements.

We maintain a comprehensive quality assurance and quality control program, which includes documentation of all material specifications, operating procedures, equipment maintenance and quality control methods. Our U.S. and European quality systems are based on the requirements of ISO13485 and the applicable regulations imposed by the FDA on medical device manufacturers. We are accredited by the AATB, and we are registered with the FDA as a Tissue Bank and as a medical device manufacturer. The FDA may audit our facilities at any time.

Our production facilities are adequate for our current requirements but we anticipate the need for a modest expansion of our Arlington, Tennessee, facilities in the future as we continue to introduce new products and processes and grow our business.

Sales and Marketing

Our sales and marketing efforts are focused primarily on orthopaedic surgeons, who typically are the decision-makers in orthopaedic device purchases. We have established relationships with surgeons who we believe are leaders in their chosen orthopaedic specialties. We involve these surgeons and our marketing personnel in all stages of bringing a product to market - from initial product development to product launch. As a result, we have a well educated, highly involved marketing staff and an established, global base of well respected surgeons, who serve as advocates to promote our products in the orthopaedic community.

In 2006, we began working with tennis legend Jimmy Connors to educate patients about advances in products and surgical techniques for treatment of chronic hip pain. Mr. Connors is a recipient of our CONSERVE ® Total Hip with BFH ® Technology, which was implanted using our PATH ® MIS surgical technique. As a focal point of our education outreach program, Mr. Connors’ personal story of successful hip surgery is detailed on the website www.jimmysnewhip.com, along with other resources for patients who may be exploring surgical options for treatment of their hip pain.

We offer clinical symposia and seminars, publish advertisements and the results of clinical studies in industry publications, and offer surgeon-to-surgeon education on our new products using our surgeon advisors in an instructional capacity. Additionally, approximately 16,000 practicing orthopaedic surgeons in the U.S. receive information on our latest products through our distribution network, our website and brochure mailings.

We sell our products in the U.S. through a sales force of approximately 340 people as of December 31, 2006. This sales force primarily consists of independent, commission-based sales representatives and distributors engaged principally in the business of supplying orthopaedic products to hospitals in their geographic areas. Our U.S. field sales force is supported by our Tennessee-based sales and marketing organization. Our independent distributors and sales representatives are provided opportunities for product training throughout the year.

Our products are marketed internationally through a combination of direct sales offices in certain key international markets and distributors in other markets. We have sales offices in France, Italy, the United Kingdom, Belgium, Germany, Spain, the Netherlands, Japan and Canada that employ direct sales employees and use independent sales representatives to sell our products in their respective markets. Our products are sold in other countries in Europe, Asia, Africa, South America and Australia using stocking distribution partners and other distribution arrangements. Stocking distributors purchase products directly from us for resale to their local customers, with product ownership generally passing to the distributor upon shipment. As of December 31, 2006, through a combination of our direct sales offices and approximately 115 stocking distribution partners, we had approximately 480 international sales representatives that sell our products in over 60 countries.

Seasonal Nature of Business

We traditionally experience lower sales volumes in the third quarter than throughout the rest of the year as a result of the European holiday schedule, typically resulting in selling, general and administrative expenses and research and development expenses as a percentage of sales that are higher than throughout the rest of the year. In addition, our first quarter selling, general and administrative expenses include additional expenses that we incur in connection with the annual meeting held by the American Academy of Orthopaedic Surgeons. This meeting, which is the largest orthopaedic meeting in the world, features the presentation of scientific papers and instructional courses for orthopaedic surgeons. During this 3-day event, we display our most recent and innovative products for these surgeons.

Competition

Competition in the orthopaedic device industry is intense and is characterized by extensive research efforts and rapid technological progress. Competitors include major companies in both the orthopaedic and biologics industries, as well as academic institutions and other public and private research organizations that continue to conduct research, seek patent protection and establish arrangements for commercializing products that will compete with our products.

The primary competitive factors facing us include price, quality, innovative design and technical capability, breadth of product line, scale of operations and distribution capabilities. Our current and future competitors may have greater resources, more widely accepted and innovative products, less invasive therapies, greater technical capabilities and stronger name recognition than we do. Our ability to compete is affected by our ability to:

    develop new products and innovative technologies;
 
    obtain regulatory clearance and compliance for our products;
 
    manufacture and sell our products cost-effectively;
 
    meet all relevant quality standards for our products and their markets;
 
    respond to competitive pressures specific to each of our geographic markets, including our ability to enforce non-compete agreements;
 
    protect the proprietary technology of our products and manufacturing processes;
 
    market our products;
 
    attract and retain skilled employees and sales representatives; and
 
    maintain and establish distribution relationships.



Intellectual Property

We currently own or have licenses to use more than 200 patents and pending patent applications throughout the world. We seek to aggressively protect technology, inventions and improvements that are considered important through the use of patents and trade secrets in the U.S. and significant foreign markets. We manufacture and market the products both under patents and license agreements with other parties. These patents have a defined life, and expire from time to time.

Our knowledge and experience, creative product development, marketing staff and trade secret information with respect to manufacturing processes, materials and product design, are as important as our patents in maintaining our proprietary product lines. As a condition of employment, we require all employees to execute a confidentiality agreement with us relating to proprietary information and patent rights.

There can be no assurances that our patents will provide competitive advantages for our products, or that

competitors will not challenge or circumvent these rights. In addition, there can be no assurances that the United States Patent and Trademark Office (USPTO) will issue any of our pending patent applications. The USPTO may deny or require a significant narrowing of the claims in our pending patent applications and the patents issuing from such applications. Any patents issuing from the pending patent applications may not provide us with significant commercial protection. We could incur substantial costs in proceedings before the USPTO. These proceedings could result in adverse decisions as to the priority of our inventions and the narrowing or invalidation of claims in issued patents. Additionally, the laws of some of the countries in which our products are or may be sold may not protect our intellectual property to the same extent as the laws in the U.S. or at all.

While we do not believe that any of our products infringe any valid claims of patents or other proprietary rights held by others, there can be no assurances that we do not infringe any patents or other proprietary rights held by them. If our products were found to infringe any proprietary right of another party, we could be required to pay significant damages or license fees to such party or cease production, marketing and distribution of those products. Litigation may also be necessary to enforce patent rights we hold or to protect trade secrets or techniques we own. We are currently involved in an intellectual property lawsuit with Howmedica Osteonics Corp., a subsidiary of Stryker Corporation. See “Legal Proceedings” for an additional discussion of this lawsuit.

We also rely on trade secrets and other unpatented proprietary technology. There can be no assurances that we can meaningfully protect our rights in our unpatented proprietary technology or that others will not independently develop substantially equivalent proprietary products or processes or otherwise gain access to our proprietary technology. We seek to protect our trade secrets and proprietary know-how, in part, with confidentiality agreements with employees and consultants. There can be no assurances, however, that the agreements will not be breached, adequate remedies for any breach would be available, or competitors will not discover or independently develop our trade secrets.

Third-Party Reimbursement

In the U.S., as well as in foreign countries, government-funded or private insurance programs, commonly known as third-party payors, pay a significant portion of the cost of a patient’s medical expenses. A uniform policy of reimbursement does not exist among all of these payors relative to payment of claims or enforcement of guidelines established by the Centers for Medicare and Medicaid Services (CMS). Therefore, reimbursement can be quite different from payor to payor as well as from one region of the country to another. We believe that reimbursement is an important factor in the success of any medical device. Consequently, we seek to obtain reimbursement for all of our products.

Reimbursement in the U.S. depends on our ability to obtain FDA clearances and approvals to market our products. Reimbursement also depends on our ability to demonstrate the short-term and long-term clinical and cost-effectiveness of our products from the results obtained from our clinical experience and formal clinical trials. We present these results at major scientific and medical meetings and publish them in respected, peer-reviewed medical journals.

All U.S. and foreign third-party reimbursement programs, whether government funded or insured commercially, are developing increasingly sophisticated methods of controlling health care costs through prospective reimbursement and capitation programs, group purchasing, redesign of benefits, second opinions required prior to major surgery, careful review of bills, encouragement of healthier lifestyles and exploration of more cost-effective methods of delivering health care. These types of programs can potentially limit the amount which health care providers may be willing to pay for medical devices.

CMS has adopted prospective payment systems with respect to U.S. government funded patients for services performed in hospital settings and all approved procedures performed in ambulatory surgery centers. These prospective payment systems reimburse hospitals according to a system of groupings that classify patients into clinically cohesive groups based on similar diagnosis and consumption of hospital resources. The payment rate for each grouping is established by CMS based on the national average cost associated with each category of treatment. The prospective payment is intended to reimburse the facility for all costs associated with the patient’s care, including all medical devices.

The majority of non-government funded payors have adopted payment systems based on the prospective payment methodology established by CMS. In some cases, however, particularly within the outpatient surgery center setting, providers continue to issue payments based on each component of the patient’s care. In these situations, facilities charge payors separately for any medical devices used during treatment. Reimbursement is typically based on the cost of the device plus a small administrative fee.

If adequate levels of reimbursement from third-party payors outside of the U.S. are not obtained, international sales of our products may decline. Outside of the U.S., reimbursement systems vary significantly by country. Many foreign markets have government-managed health care systems that govern reimbursement for new medical devices and procedures. Canada and some European and Asian countries, in particular France, Japan, Taiwan and Korea, have tightened reimbursement rates. Additionally, some foreign reimbursement systems provide for limited payments in a given period and, therefore, result in extended payment periods.

Employees

As of December 31, 2006, we employed approximately 1,060 people in the following areas: 440 in manufacturing, 340 in sales and marketing, 150 in administration and 130 in research and development. We believe that we have an excellent relationship with our employees.

Environmental

Our operations and properties are subject to extensive federal, state, local and foreign environmental protection and health and safety laws and regulations. These laws and regulations govern, among other things, the generation, storage, handling, use and transportation of hazardous materials and the handling and disposal of hazardous waste generated at our facilities. Under such laws and regulations, we are required to obtain permits from governmental authorities for some of our operations. If we violate or fail to comply with these laws, regulations or permits, we could be fined or otherwise sanctioned by regulators. Under some environmental laws and regulations, we could also be held responsible for all of the costs relating to any contamination at our past or present facilities and at third-party waste disposal sites.

We believe our costs of complying with current and future environmental laws, regulations and permits, and our liabilities arising from past or future releases of, or exposure to, hazardous substances will not materially adversely affect our business, results of operations or financial condition, although there can be no assurances that they will not.

Available Information

Our website is located at www.wmt.com . We make available free of charge through this website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed with or furnished to the Securities and Exchange Commission (SEC) pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after they are electronically filed with or furnished to the SEC.

Item 1A. Risk Factors.

Our business and its future performance may be affected by various factors, the most significant of which are discussed below.

We are subject to substantial government regulation that could have a material adverse effect on our business.

The production and marketing of our products and our ongoing research and development, preclinical testing and clinical trial activities are subject to extensive regulation and review by numerous governmental authorities both in the U.S. and abroad. See “Business — Government Regulation” for further details on this process. U.S. and foreign regulations govern the testing, marketing and registration of new medical devices, in addition to regulating

manufacturing practices, reporting, labeling and recordkeeping procedures. The regulatory process requires significant time, effort and expenditures to bring our products to market, and we cannot be assured that any of our products will be approved. Our failure to comply with applicable regulatory requirements could result in these governmental authorities:   imposing fines and penalties on us;   preventing us from manufacturing or selling our products;   bringing civil or criminal charges against us;   delaying the introduction of our new products into the market;   recalling or seizing our products; or   withdrawing or denying approvals or clearances for our products.

Even if regulatory approval or clearance of a product is granted, this could result in limitations on the uses for which the product may be labeled and promoted. Further, for a marketed product, its manufacturer and manufacturing facilities are subject to periodic review and inspection. Subsequent discovery of problems with a product, manufacturer or facility may result in restrictions on the product, manufacturer or facility, including withdrawal of the product from the market or other enforcement actions.

We are currently conducting clinical studies of some of our products under an IDE. Clinical studies must be conducted in compliance with FDA regulations, or the FDA may take enforcement action. The data collected from these clinical studies will ultimately be used to support market clearance for these products. There is no assurance that the FDA will accept the data from these clinical studies or that it will ultimately allow market clearance for these products.

We are subject to various federal and state laws concerning health care fraud and abuse, including false claims laws, anti-kickback laws, and physician self-referral laws. Violations of these laws can result in criminal and/or civil punishment, including fines, imprisonment, and in the U.S., exclusion from participation in government health care programs. The scope of these laws and related regulations are expanding and their interpretation is evolving. There is very little precedent related to these laws and regulations. Increased funding for enforcement of these laws and regulations has resulted in greater scrutiny of marketing practices in our industry and resulted in several government investigations by various government authorities. If a governmental authority were to determine that we do not comply with these laws and regulations, then we and our officers and employees, could be subject to criminal and civil sanctions, including exclusion from participation in federal health care reimbursement programs.

In order to market our product devices in the member countries of the EU, we are required to comply with the Medical Devices Directive and obtain CE mark certification. CE mark certification is the European symbol of adherence to quality assurance standards and compliance with applicable European Medical Device Directives. Under the Medical Devices Directive, all medical devices including active implants must qualify for CE marking. In August 2005, an EU Medical Devices Directive changed the classification of hip, knee, and shoulder implants from class IIb to class III. The transition period for these changes begins September 1, 2007. Upon reclassification to class III, manufacturers will be required to assemble significantly more documentation and submit it to their Notified Body for formal approval prior to affixing the CE mark to their product and packaging. We intend to comply with the Medical Devices Directive for all of our products manufactured and sold in the EU. However, there can be no assurance that our products will be approved for CE marking in a timely manner or at all.

Modifications to our marketed devices may require FDA regulatory clearances or approvals or require us to cease marketing or recall the modified devices until such clearances or approvals are obtained.

When required, the products we market in the U.S. have obtained premarket notification under Section 510(k) of the FDC Act or were exempt from the 510(k) clearance process. We have modified some of our products and product labeling since obtaining 510(k) clearance, but we do not believe these modifications require us to submit new 510(k) notifications. However, if the FDA disagrees with us and requires us to submit a new 510(k) notification for modifications to our existing products, we may be the subject of enforcement actions by the FDA and be required to stop marketing the products while the FDA reviews the 510(k) notification. If the FDA requires us to go through a lengthier, more rigorous examination than we had expected, our product introductions or modifications could be delayed or canceled, which could cause our sales to decline. In addition, the FDA may determine that future products will require the more costly, lengthy and uncertain PMA application process. Products that are approved through a PMA application generally need FDA approval before they can be modified. See “Business — Government Regulation.”

If market clearance is not obtained for launch of the CONSERVE ® Plus implant in the U.S., growth of our hip product line could be impacted.

Our CONSERVE ® Plus Resurfacing Implant is available outside the U.S. There can be no assurance that the sale of our CONSERVE ® Plus product in the U.S. will be cleared by the FDA in a timely manner or at all, which could have a significant impact on the future growth of our hip product line.

Our biologics business is subject to emerging governmental regulations that can significantly impact our business.

The FDA has statutory authority to regulate allograft-based products, processing and materials. The FDA has been working to establish a more comprehensive regulatory framework for allograft-based products, which are principally derived from cadaveric tissue. The framework developed by the FDA establishes criteria for determining whether a particular human tissue-based product will be classified as human tissue, a medical device or biologic drug requiring premarket clearance or approval. All tissue-based products are subject to extensive FDA regulation, including a requirement that ensures that diseases are not transmitted to tissue recipients. The FDA has also proposed extensive additional regulations that would govern the processing and distribution of all allograft products. Consent to use the donor’s tissue must also be obtained. The regulations for allograft-based products are still developing. From time to time, the FDA reviews these products and may informally suggest to us how these products should be classified. If a human tissue-based product is considered human tissue, it does not require FDA clearance or approval before being marketed. If it is considered a medical device or biologic drug, then FDA clearance or approval may be required.

Additionally, our biologics business involves the procurement and transplantation of allograft tissue, which is subject to federal regulation under NOTA. NOTA prohibits the sale of human organs, including bone and other human tissue, for valuable consideration within the meaning of NOTA. NOTA permits the payment of reasonable expenses associated with the transportation, processing, preservation, quality control and storage of human tissue. We currently charge our customers for these expenses. In the future, if NOTA is amended or reinterpreted, we may not be able to charge these expenses to our customers and, as a result, our business could be adversely affected.

Our principal allograft-based biologics offerings include ALLOMATRIX ® , GRAFTJACKET ® and IGNITE ® products.

If we fail to compete successfully in the future against our existing or potential competitors, our sales and operating results may be negatively affected and we may not achieve future growth.

The markets for our products are highly competitive and dominated by a small number of large companies. We may not be able to meet the prices offered by our competitors, or offer products similar to or more desirable than those offered by our competitors. See “Business — Competition.”

If we lose one of our key suppliers, we may be unable to meet customer orders for our products in a timely manner or within our budget.

We rely on a limited number of suppliers for the components used in our products. Our reconstructive joint devices are produced from various surgical grades of titanium, cobalt chrome and stainless steel, various grades of high-density polyethylenes, silicone elastomer and ceramics. We rely on one source to supply us with a certain grade of cobalt chrome alloy and one supplier for the silicone elastomer used in our extremity products. We are aware of only two suppliers of silicone elastomer to the medical device industry for permanent implant usage. Additionally, we rely on one supplier of ceramics for use in our hip products.

In addition, for our biologics products, we presently depend upon a single supplier as our source for DBM and CBM, and any failure to obtain DBM and CBM from this source in a timely manner will deplete levels of on-hand raw materials inventory and could interfere with our ability to process and distribute allograft products. During 2007, we are expecting a single not-for-profit tissue bank to meet all of our DBM and CBM order requirements, a key component in the allograft products we currently produce, market and distribute. We cannot be sure that our supply of DBM and CBM will continue to be available at current levels or will be sufficient to meet our needs, or that future suppliers of DBM and CBM will be free from FDA regulatory action impacting their sale of DBM and CBM. Since there is a small number of suppliers, if we cannot continue to obtain DBM and CBM from our current source in volumes sufficient to meet our needs, we may not be able to locate replacement sources of DBM and CBM on commercially reasonable terms, if at all. This could have the effect of interrupting our business, which could adversely affect our sales. Further, we rely on one supplier for our GRAFTJACKET ® family of soft tissue repair and graft containment products, as well as one supplier for our ADCON ® Gel products. Sales of our GRAFTJACKET ® family of soft tissue repair products have grown to represent a significant portion of our total consolidated net sales.

Suppliers of raw materials and components may decide, or be required, for reasons beyond our control to cease supplying raw materials and components to us. FDA regulations may require additional testing of any raw materials or components from new suppliers prior to our use of these materials or components and in the case of a device with a PMA application, we may be required to obtain prior FDA permission, either of which could delay or prevent our access to or use of such raw materials or components.

We derive a significant portion of our sales from operations in international markets that are subject to political, economic and social instability.

We derive a significant portion of our sales from operations in international markets. Our international distribution system consists of nine direct sales offices and approximately 115 stocking distribution partners, which combined employ approximately 480 sales representatives who sell in over 60 countries. Most of these countries are, to some degree, subject to political, social and economic instability. For both of the years ended December 31, 2006, and 2005, approximately 38% of our net sales were derived from our international operations. Our international sales operations expose us and our representatives, agents and distributors to risks inherent in operating in foreign jurisdictions. These risks include:   the imposition of additional foreign governmental controls or regulations on orthopaedic implants and biologics products;

  new export license requirements, particularly related to our biologics products;
 
  economic instability, including currency risk between the U.S. dollar and foreign currencies, in our target markets;
 
  a shortage of high-quality international salespeople and distributors;
 
  loss of any key personnel who possess proprietary knowledge or are otherwise important to our success in international markets;
 
  changes in third-party reimbursement policy that may require some of the patients who receive our implant products to directly absorb medical costs or that may necessitate our reducing selling prices for our products;
 
  changes in tariffs and other trade restrictions, particularly related to the exportation of our biologics products;
 
  work stoppages or strikes in the health care industry, such as those that have previously affected our operations in France, Canada, Korea and Finland in the past;
 
  a shortage of nurses in some of our target markets, particularly affecting our operations in France;
 
  exposure to different legal and political standards due to our conducting business in over 60 countries; and
 
  work stoppages or strikes in the south of France, where we operate our European manufacturing and logistics facilities.



Any material decrease in our foreign sales would negatively impact our profitability. Our international sales are predominately generated in Europe. In Europe, health care regulation and reimbursement for medical devices vary significantly from country to country. This changing environment could adversely affect our ability to sell our products in some European countries.

Efforts to acquire and integrate other companies or product lines could adversely affect our operations and financial results.

We may pursue acquisitions of other companies or product lines. Our ability to grow through acquisitions depends upon our ability to identify, negotiate, complete and integrate suitable acquisitions and to obtain any necessary financing. Even if we complete acquisitions, we may also experience:

  difficulties in integrating any acquired companies, personnel and products into our existing business;
 
  delays in realizing the benefits of the acquired company or products;
 
  diversion of our management’s time and attention from other business concerns;
 
  limited or no direct prior experience in new markets or countries we may enter;
 
  higher costs of integration than we anticipated; or



  difficulties in retaining key employees of the acquired business who are necessary to manage these acquisitions.

In addition, an acquisition could materially impair our operating results by causing us to incur debt or requiring us to amortize acquisition expenses and acquired assets.

If our patents and other intellectual property rights do not adequately protect our products, we may lose market share to our competitors and be unable to operate our business profitably.

We rely on patents, trade secrets, copyrights, know-how, trademarks, license agreements and contractual provisions to establish our intellectual property rights and protect our products. See “Business — Intellectual Property.” These legal means, however, afford only limited protection and may not adequately protect our rights. In addition, we cannot be assured that any of our pending patent applications will issue. The USPTO may deny or require a significant narrowing of the claims in our pending patent applications and the patents issuing from such applications. Any patents issuing from the pending patent applications may not provide us with significant commercial protection. We could incur substantial costs in proceedings before the USPTO. These proceedings could result in adverse decisions as to the priority of our inventions and the narrowing or invalidation of claims in issued patents. In addition, the laws of some of the countries in which our products are or may be sold may not protect our intellectual property to the same extent as U.S. laws or at all. We also may be unable to protect our rights in trade secrets and unpatented proprietary technology in these countries.

In addition, we hold licenses from third parties that are necessary to utilize certain technologies used in the design and manufacturing of some of our products. The loss of such licenses would prevent us from manufacturing, marketing and selling these products, which could harm our business.

We seek to protect our trade secrets, know-how and other unpatented proprietary technology, in part, with confidentiality agreements with our employees, independent distributors and consultants. We cannot be assured, however, that the agreements will not be breached, adequate remedies for any breach would be available or our trade secrets, know-how, and other unpatented proprietary technology will not otherwise become known to or independently developed by our competitors.

If we lose any existing or future intellectual property lawsuits, a court could require us to pay significant damages or prevent us from selling our products.

The medical device industry is litigious with respect to patents and other intellectual property rights. Companies in the medical device industry have used intellectual property litigation to gain a competitive advantage. We are currently involved in an intellectual property lawsuit with Howmedica Osteonics Corp., a subsidiary of Stryker Corporation, where it is alleged that our ADVANCE ® Knee product line infringes one of Howmedica’s patents. See “Legal Proceedings” for more information regarding this lawsuit. If Howmedica were to succeed in obtaining the relief it claims, the court could award damages to Howmedica and impose an injunction against further sales of our product. If a monetary judgment is rendered against us, we may be forced to raise or borrow funds, as a supplement to any available insurance claim proceeds, to pay the damages award.

In the future, we may become a party to other lawsuits involving patents or other intellectual property. A legal proceeding, regardless of the outcome, could drain our financial resources and divert the time and effort of our management. If we lose one of these proceedings, a court, or a similar foreign governing body, could require us to pay significant damages to third parties, require us to seek licenses from third parties and pay ongoing royalties, require us to redesign our products, or prevent us from manufacturing, using or selling our products. In addition to being costly, protracted litigation to defend or prosecute our intellectual property

rights could result in our customers or potential customers deferring or limiting their purchase or use of the affected products until resolution of the litigation.

If product liability lawsuits are brought against us, our business may be harmed.

The manufacture and sale of medical devices exposes us to significant risk of product liability claims. In the past, we have had a number of product liability claims relating to our products, none of which either individually, or in the aggregate, have resulted in a material negative impact on our business. In the future, we may be subject to additional product liability claims, some of which may have a negative impact on our business. Additionally, we could experience a material design or manufacturing failure in our products, a quality system failure, other safety issues, or heightened regulatory scrutiny that would warrant a recall of some of our products. Our existing product liability insurance coverage may be inadequate to protect us from any liabilities we might incur. If a product liability claim or series of claims is brought against us for uninsured liabilities or in excess of our insurance coverage, our business could suffer. In addition, a recall of some of our products, whether or not the result of a product liability claim, could result in significant costs and loss of customers.

Further, in 1993, our predecessor company, Wright Medical Technology, Inc. (the Predecessor Company), acquired substantially all of the assets of the large joint orthopaedic implant business from Dow Corning Corporation (DCC). DCC retains liability for matters arising from certain conduct of DCC prior to June 30, 1993. As such, DCC has agreed to indemnify the Predecessor Company against all liability for all products manufactured prior to the acquisition except for products provided under the Predecessor Company’s 1993 agreement with DCC pursuant to which the Predecessor Company purchased certain small joint orthopaedic implants for worldwide distribution. The Predecessor Company was notified in 1995 that DCC, which filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code, would no longer defend the Predecessor Company in such matters until it received further direction from the bankruptcy court. There are several appeals regarding the confirmed plan of reorganization pending before the U.S. District Court in Detroit, Michigan, which have delayed implementation of the plan. There can be no assurance that DCC will indemnify the Predecessor Company or Wright on any claims in the future. Further, neither the Predecessor Company nor Wright maintains insurance for claims arising on products sold by DCC.

If we are unable to continue to develop and market new products and technologies, we may experience a decrease in demand for our products or our products could become obsolete, and our business would suffer

We are continually engaged in product development and improvement programs, and new products represent a significant component of our growth rate. We may be unable to compete effectively with our competitors unless we can keep up with existing or new products and technologies in the orthopaedic implant market. If we do not continue to introduce new products and technologies, or if those products and technologies are not accepted, we may not be successful. Additionally, our competitors’ new products and technologies may beat our products to market, may be more effective or less expensive than our products or may render our products obsolete. See “Business — Competition.”

Our business could suffer if the medical community does not continue to accept allograft technology.

New allograft products, technologies and enhancements may never achieve broad market acceptance due to numerous factors, including:

  lack of clinical acceptance of allograft products and related technologies;
 
  the introduction of competitive tissue repair treatment options that render allograft products and



    technologies too expensive and obsolete;
 
  lack of available third-party reimbursement;
 
  the inability to train surgeons in the use of allograft products and technologies;
 
  the risk of disease transmission; and
 
  ethical concerns about the commercial aspects of harvesting cadaveric tissue.



Market acceptance will also depend on the ability to demonstrate that existing and new allografts and technologies are attractive alternatives to existing tissue repair treatment options. To demonstrate this, we rely upon surgeon evaluations of the clinical safety, efficacy, ease of use, reliability and cost effectiveness of our tissue repair options and technologies. Recommendations and endorsements by influential surgeons are important to the commercial success of allograft products and technologies. In addition, several countries, notably Japan, prohibit the use of allografts. If allograft products and technologies are not broadly accepted in the marketplace, we may not achieve a competitive position in the market.

If adequate levels of reimbursement from third-party payors for our products are not obtained, surgeons and patients may be reluctant to use our products and our sales may decline.

In the U.S., health care providers that purchase our products generally rely on third-party payors, principally federal Medicare, state Medicaid and private health insurance plans, to pay for all or a portion of the cost of joint reconstructive procedures and products utilized in those procedures. We may be unable to sell our products on a profitable basis if third-party payors deny coverage or reduce their current levels of reimbursement. Our sales depend largely on governmental health care programs and private health insurers reimbursing patients’ medical expenses. Surgeons, hospitals and other health care providers may not purchase our products if they do not receive satisfactory reimbursement from these third-party payors for the cost of the procedures using our products. Payors continue to review their coverage policies carefully for existing and new therapies and can, without notice, deny coverage for treatments that include the use of our products.

In addition, some health care providers in the U.S. have adopted or are considering a managed care system in which the providers contract to provide comprehensive heath care for a fixed cost per person. Health care providers may attempt to control costs by authorizing fewer elective surgical procedures, including joint reconstructive surgeries, or by requiring the use of the least expensive implant available.

If adequate levels of reimbursement from third-party payors outside of the U.S. are not obtained, international sales of our products may decline. Outside of the U.S., reimbursement systems vary significantly by country. Many foreign markets have government-managed health care systems that govern reimbursement for medical devices and procedures. Canada, and some European and Asian countries, in particular France, Japan, Taiwan and Korea, have tightened reimbursement rates. Additionally, some foreign reimbursement systems provide for limited payments in a given period and therefore result in extended payment periods. See “Business — Third-Party Reimbursement” for more information regarding reimbursement in the U.S. and abroad.

If surgeons do not recommend and endorse our products, our sales may decline or we may be unable to increase our sales and profits.

In order for us to sell our products, surgeons must recommend and endorse them. We may not obtain the necessary recommendations or endorsements from surgeons. Acceptance of our products depends on

educating the medical community as to the distinctive characteristics, perceived benefits, clinical efficacy and cost-effectiveness of our products compared to products of our competitors and on training surgeons in the proper application of our products.

We rely on our independent sales distributors and sales representatives to market and sell our products.

Our success depends largely upon marketing arrangements with independent sales distributors and sales representatives, in particular their sales and service expertise and relationships with the customers in the marketplace. Independent distributors and sales representatives may terminate their relationships with us or devote insufficient sales efforts to our products. We do not control our independent distributors and they may not be successful in implementing our marketing plans. Our failure to maintain our existing relationships with our independent distributors and sales representatives could have an adverse effect on our operations. Similarly, our failure to recruit and retain additional skilled independent sales distributors and sales representatives could have an adverse effect on our operations. We have experienced turnover with some of our independent distributors in the past which adversely affected short-term financial results while we transitioned to new independent distributors. While we believe these transitions have been managed effectively, similar occurrences could happen in the future with different results which could have a greater adverse effect on our operations than we have previously experienced.

Fluctuations in insurance cost and availability could adversely affect our profitability or our risk management profile.

We hold a number of insurance policies, including product liability insurance, directors’ and officers’ liability insurance, property insurance and workers’ compensation insurance. If the costs of maintaining adequate insurance coverage should increase significantly in the future, our operating results could be materially adversely impacted. Likewise, if the availability of any of our current insurance coverage should become unavailable to us or economically impractical, we would be required to operate our business without indemnity from commercial insurance providers.

If we cannot retain our key personnel, we will not be able to manage and operate successfully and we may not be able to meet our strategic objectives.

Our continued success depends, in part, upon key managerial, scientific, sales and technical personnel, as well as our ability to continue to attract and retain additional highly qualified personnel. We compete for such personnel with other companies, academic institutions, governmental entities and other organizations. There can be no assurance that we will be successful in retaining our current personnel or in hiring or retaining qualified personnel in the future. Loss of key personnel or the inability to hire or retain qualified personnel in the future could have a material adverse effect on our ability to operate successfully. Further, any inability on our part to enforce non-compete arrangements related to key personnel who have left the business could have a material adverse effect on our business.

If a natural or man-made disaster strikes our manufacturing facilities, we could be unable to manufacture our products for a substantial amount of time and our sales could decline.

We have principally relied to date on our manufacturing facilities in Arlington, Tennessee, and Toulon, France. These facilities and the manufacturing equipment we use to produce our products would be difficult to replace and could require substantial lead-time to repair or replace. Our facilities may be affected by natural or man-made disasters. In the event one of our facilities was affected by a disaster, we would be forced to rely on third-party manufacturers or shift production to our other manufacturing facility. Although we believe we possess adequate insurance for damage to our property and the disruption of our business

from casualties, such insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms or at all.

Our business plan relies on certain assumptions about the market for our products, which, if incorrect, may adversely affect our profitability.

We believe that the aging of the general population and increasingly active lifestyles will continue and that these trends will increase the need for our orthopaedic implant products. The projected demand for our products could materially differ from actual demand if our assumptions regarding these trends and acceptance of our products by the medical community prove to be incorrect or do not materialize, or if non-surgical treatments gain more widespread acceptance as a viable alternative to orthopaedic implants.

Fluctuations in foreign currency exchange rates could result in declines in our reported sales and earnings.

Since a majority of our international sales are denominated in local currencies and not in U.S. dollars, our reported sales and earnings are subject to fluctuations in foreign exchange rates. Our international net sales were unfavorably affected by the impact of foreign currency fluctuations totaling approximately $300,000 in 2006 and favorably impacted by $400,000 in 2005. We currently employ a derivative program using 30-day foreign currency forward contracts to mitigate the risk of currency fluctuations on our intercompany receivable and payable balances that are denominated in foreign currencies. These forward contracts are expected to offset the transactional gains and losses on the related intercompany balances. These forward contracts are not designated as hedging instruments under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. Accordingly, the changes in the fair value and the settlement of the contracts are recognized in the period incurred.

Our quarterly operating results are subject to substantial fluctuations and you should not rely on them as an indication of our future results.

Our quarterly operating results may vary significantly due to a combination of factors, many of which are beyond our control. These factors include:

  demand for products, which historically has been lowest in the third quarter;
 
  our ability to meet the demand for our products;
 
  increased competition;
 
  the number, timing and significance of new products and product introductions and enhancements by us and our competitors;
 
  our ability to develop, introduce and market new and enhanced versions of our products on a timely basis;
 
  changes in pricing policies by us and our competitors;
 
  changes in the treatment practices of orthopaedic surgeons;
 
  changes in distributor relationships and sales force size and composition;



  the timing of material expense- or income-generating events and the related recognition of their associated financial impact;
 
  the timing of significant orders and shipments;
 
  availability of raw materials;
 
  work stoppages or strikes in the health care industry;
 
  changes in FDA and foreign governmental regulatory policies, requirements and enforcement practices;
 
  changes in accounting policies, estimates, and treatments; and
 
  general economic factors.



We believe that our quarterly sales and operating results may vary significantly in the future and that period-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indications of future performance. We cannot assure you that our sales will increase or be sustained in future periods or that we will be profitable in any future period. Any shortfalls in sales or earnings from levels expected by securities or orthopaedic industry analysts could have an immediate and significant adverse effect on the trading price of our common stock in any given period.

Our business could be adversely impacted if we have deficiencies in our internal control over financial reporting.

The design and effectiveness of our internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. As part of management’s review of our internal control over financial reporting for the year ended December 31, 2006, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, management concluded that, as of December 31, 2006, there was a material weakness in our internal control over financial reporting related to our method of calculating depreciation expense for our surgical instruments, as discussed in “Controls and Procedures.”

We believe that the controls we have implemented have been designed to remediate this material weakness as of the filing date of this annual report. While management will continue to review the effectiveness of our internal control over financial reporting, we cannot assure you that our internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Other deficiencies, particularly a material weakness in internal control over financial reporting, which may occur in the future, could result in misstatements of our results of operations, restatements of our financial statements, a decline in our stock price, or otherwise materially adversely affect our business, reputation, results of operation, financial condition or liquidity.
