THE CLINICAL-RESULTS OF THE PFC KNEE PROSTHESIS

Seventy-six cementless primary total knee arthroplasties using the Press Fit Condylar (PFC) total knee arthroplasty system were performed on 60 consecutive patients between May 1986 and January 1990. Mean follow-up time after total knee arthroplasty was 3.9 years (range, 24-72 months), with an average Knee Society Knee Score rating preoperatively of 52.96 +/- 14.67 and postoperatively of 93.71 +/- 9.59. The average Knee Society function score preoperatively was 40.41 +/- 17.58 and postoperatively was 93.51 +/- 10.82. Lucencies of greater than or equal to 1 mm were present at the prosthesis or patellar components in 36 of the knees examined. However, despite the presence of radiolucencies, the clinical outcome remained excellent.
