Primary Outcome Measures:
  • Knee Society Scores [ Time Frame: Pre-operative, 6 and 12 months and annually thereafter for at least 5 years. ]
    The Knee Society Score (KSS) is comprised to two sections (each worth 100 points) for a maximum 200 points. One section is the Knee Society Clinical Score (KSCS) - points are given for pain, motion, and stability and points are deducted for flexion contracture, extension lag, and misalignment. The other section is the Knee Society Functional Score (KSFS) - points are assigned for walking distances and climbing stairs and points are deducted for use of walking aids. For each section, a score of 80-100 = excellent, 70-79 = good; 60-69 = fair; and < 60 = poor.


Secondary Outcome Measures:
  • Complications/Revisions [ Time Frame: On-going to end of study. ]
  • Medical Imaging [ Time Frame: Pre-operative, 6 and 12 months and annually thereafter for at least 5 years. ]
  • SF-12 Patient Outcomes [ Time Frame: Pre-operative, 6 and 12 months and annually thereafter for at least 5 years. ]

Detailed Description:
This study will evaluate the clinical performance of rotating platform and fixed bearing knee implants. This will be done by obtaining a series of primary total knee replacements. Patients will receive either the P.F.C.® Sigma™ Rotating Platform Cruciate Retaining Knee System or the P.F.C.® Sigma™ Fixed Cruciate Retaining Knee System and assignment is randomized.
