Total condylar knee arthroplasty - 16-to 21-year results

This study presents long term results of arthroplasty with posterior crucia te retention using the Total Condylar Knee implant. From 1976 to 1982, 139 patients had 139 knee arthroplasties using Total Condylar Knee prostheses, Sixty-three patients (72 knees) mere available for followup at a minimum of 16 years (range, 16-21 years). The average age of the patients at the time of surgery was 61 years. There were 21 men and 42 women, Patients with 68 knees had osteoarthrosis, three had rheumatoid arthritis and one had posttr aumatic arthritis. There were live delayed complications, One patient tone knee) underwent revision surgery and two patients (two knees) declined revi sion surgery because they mere considered to be high surgical risks, as det ermined by their internists, The average preoperative score was 40.3 points and improved to 88.4 points at followup. Eighty-seven percent of the patie nts had a score equal to or more than 85 points at last evaluation, Prosthe sis survivorship at 20 years was 98.6% for patients who had revision surger y, No femoral components were revised for aseptic loosening, Retention of t he posterior cruciate in Total Condylar Knee prosthesis produces results co mparable with the results of the original Total Condylar Knee prosthesis wi th cruciate sacrifice.
