Brief Summary
Analyze clinical data for a group of subjects implanted with a new surgical device designed to reduce the incidence of patellar crepitus following PCL-substituting TKA and compare that to a control group of subjects implanted with a TKA design known to have an incidence of patellar crepitus of approximately 5%.

Outcome Measures
Primary Outcomes (1)
Evaluate for the Incidence of Patellar Crepitus Requiring Non-operative vs. Operative Treatment of Both the Study and Control Groups at a Minimum of 12 Months Following the TKA (Total Knee Arthroplasty) Procedure in Each Subject.
The incidence of patellar crepitus and clunk will be statistically compared between the study (PFC Sigma HP PS TKA) and control (PFC Sigma PS TKA groups). Based on a strength analysis to determine a theoretical reduction in the incidence of patellar crepitus from 5% to 2%, a study group of 625 subjects in both the control and study ggroups will be required. Each group will also be statistically analyzed using the following variables: overall crepitus incidence, incidence of crepitus requiring only non-operative treatment vs. those requiring operative treatment to manage this complication.
