WARSAW, IN – Aug. 19, 2011DePuy Orthopaedics, Inc. (DePuy) has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for use of TRUMATCH® Personalized Solutions with the company’s SIGMA®Fixed-Bearing Knee System, one of the most widely used knee systems in the world.

TRUMATCH Personalized Solutions, which the company announced is available immediately, is a surgical instrumentation and computer software system that is designed to aid in knee implant positioning and procedure efficiency. TRUMATCH Solutions helps reduce costs by decreasing OR time by an average of 35 minutes.[1] Procedures require less instrumentation and eliminate up to nine surgical steps compared to total knee replacement performed without TRUMATCH Solutions.

“TRUMATCH technology helps surgeons consistently provide knee replacement patients a customized fit and enables them to do the operation in less time,” said Daniel P. Hoeffel, MD, of Summit Orthopaedic Group, St. Paul, Minnesota.* “Patients, surgeons and the health care system all benefit from advancements in technology that provide greater efficiencies and individualize treatment.”

TRUMATCH Solutions is the first system to utilize CT scans and computer software to guide the development and production of femoral and tibial cutting blocks that are individually prepared to match the actual bone surfaces of each patient. Precise positioning of the knee implant is critical to its overall performance.[2] Also, the use of CT scans, rather than MRIs, results in improved bone imaging, less scanning time and lower costs.[3]

“TRUMATCH Personalized Solutions, only available from DePuy, represents a meaningful advance for knee replacement patients,” said Andrew Ekdahl, President, DePuy Orthopaedics. “This proprietary system is a win for patients, surgeons and hospitals that has the potential to improve patient care while reducing costs --a very important combination in health care today.”

The FDA clearance of TRUMATCH Solutions was based in part on mechanical and alignment accuracy testing. TRUMATCH Solutions is available in 12 other countries.

SIGMA® Knee System
The SIGMA®Knee System has been provided for nearly 1 million patients.[4] In fact, one study has shown that 10 years after surgery, 99.6 percent of patients still depend on SIGMA Knees with the fixed-bearing option in their daily lives.[5] In another study of people five to ten years after surgery with Fixed-Bearing SIGMA Knee implants, most reported that the surgery had resulted in excellent relief of pain, improved range of motion and better function of the knee.[6]

Fixed-bearing knees are the most widely used knee replacements in the United States today. The SIGMA Knee with fixed-bearing option is a leader in this type of knee system. SIGMA Fixed-Bearing Knees are based on the clinically proven P.F.C.®Knee.[7] DePuy Orthopaedics knee replacements have over 30 years of clinical experience.[8]

Important Safety Information
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 determine if knee replacement is indicated based on an individual patient’s condition.
