Non-inflammatory Arthritis Clinical Trial
Official title:
Does Implant Design Improve Postoperative Flexion?A Prospective, Randomized, Comparative, Multi-center Study Comparing PFC® Sigma™ RP Knee Versus PFC® Sigma™ RP-F Implanted in Simultaneous Bilateral Subjects
This study will evaluate whether design features of one implant design allows more knee bend than the other. Patients will have 1 design in the left knee and 1 design in their right knee. Both knee surgeries will be on the same day.
The primary objective of this study is to determine whether the passive, non-weight-bearing flexion is superior with the posterior-stabilized PFC® Sigma™ RP-F compared to the posterior-stabilized PFC® Sigma™ RP in bilateral Subjects receiving both implants and if this difference is a function of implant design. ;
