Technology in Knee Replacement
DePuy Orthopaedics, Inc., one of the world's leading orthopaedic companies, offers both a rich history of innovation in knee replacement and a long history of clinical success in knee replacement. Two types of clinically proven knee systems are available from DePuy Orthopaedics to help restore mobility and reduce pain: Fixed-Bearing and Rotating Platform Knees.
Fixed-Bearing Knees are the most widely used knee replacements.1 The design of the Sigma Fixed-Bearing Knee provides stability of the knee replacement and distributes pressure evenly throughout the joint, which helps reduce wear.

The Rotating Platform Knee is based on a revolutionary technology, the mobile-bearing knee, which DePuy Orthopaedics pioneered 30 years ago. Studies show that even after 20 years, more than 97% of these implants are still in use.2 More than one million Rotating Platform Knees have been implanted worldwide.1
