Eligibility Criteria
Inclusion Criteria:
- Male or female subjects, aged between 45 and 75 years inclusive.

5. Study Description
Brief Summary
The purpose of this study is to evaluate if the P.F.C. Sigma RPF knee accommodates functional stability with a post-operative passive range of motion of greater than 125° of flexion and to demonstrate that the range of motion does not compromise the longevity of the implant.
Detailed Description
Primary endpoint is to demonstrate that 90% of patients have a functionally stable knee that can achieve post operative range of motion of 125 degrees or greater.
The secondary endpoint is to investigate the survivorship of the P.F.C. Sigma RP-F knee at 1, 2, 3, 5, 10, 15 and 20 years
