DePuy Orthopaedics, Inc., a global leader in devices for joint replacement, announced the launch of new products in its portfolio of Sigma® Knee products that offer surgeons the ability to select from a wide range of instruments and implants based on a spectrum of patient needs and their own surgical preferences.

"The launch of these new Sigma Knee products signals a new wave of innovation that will have significant effects on patient care," said David Floyd, President, DePuy Orthopaedics, Inc. "These significant enhancements to the Sigma Knee group are the beginning of a new era of products and solutions designed to offer high performance instrumentation, customization, quicker recovery, and longer-term durability for the wide range of patients seeking knee replacement today."

DePuy Orthopaedics made the announcement at the 75th Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), where it will showcase these new products, including Sigma High Performance instruments, a new line of instruments designed to enhance procedure efficiency, surgical precision and flexibility. Designed for contemporary knee surgery, the High Performance Instruments adapt to a surgeon's specific surgical technique, including computer assisted surgery and manual surgery, with both minimally invasive and traditional open approaches. Sigma High Performance instruments were developed with a compact design to allow for smaller incisions and are soft-tissue friendly to reduce surgical trauma. This is DePuy Orthopaedics' largest introduction of instrumentation in a decade.

"Sigma High Performance Instruments are the most advanced instrumentation we have ever developed, and the initial feedback from surgeons who've already used the instruments is extremely positive. These instruments will further contribute to the excellent results seen with our Sigma Knee implants," said Tom Lavery, Vice-President Marketing, Knees. Also at AAOS DePuy Orthopaedics is introducing into the Sigma Knee product group the Sigma CR Porocoat Femur, a cement-less fixation femoral component that contains a porous coating conducive to deep bone ingrowth and better long-term fixation of the implant and the Sigma PS Femur, designed to provide today's high demand patients with enhanced function from gait to deep flexion activities, and the next generation in computer assisted knee software, Ci™ Essential Knee.

DePuy will introduce additional Sigma Knee products and services over the next 18 months. The Sigma Knee will also be part of a consumer education campaign called Sigma -- My knee. My life™. This campaign will encourage patients to talk with their surgeons about which Sigma knee replacement system will best fit their lifestyle and activity level.

About Knee Replacement

According to the AAOS more than 500,000 total knee replacements are performed in the U.S.1 The AAOS notes that more joint replacement surgeries are performed on the knee than on any other joint. In a total knee replacement, the knee is replaced by prostheses made of metal alloys, high-grade plastics and polymeric materials. Most of the other structures of the knee remain intact. Knee replacement surgery is generally recommended for patients with severe knee pain and disability caused by damage to cartilage from rheumatoid arthritis, osteoarthritis or trauma. It is highly successful in relieving pain and restoring joint function. The performance of knee replacements depends on age, weight, activity level, and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell if knee replacement is right for a patient.
