O2611 TOTAL CONDYLAR KNEE ARTHROPLASTY: AT AVERAGE OF 20 YEARS OF FOLLOW-UP

Abstract

Aim: The purpose of this study is to evaluate the longest results of Total Condylar knee arthroplasty. Material: Between 1976 and 1982, 159 consecutive primary total knee replacements were performed. All knees were followed in prospective fashion. Assessment was done by Knee Society methods. Survivorship analysis was done using the Kaplan-Meier method and analysed with log rank test. Results: No patient was lost to follow-up. One hundred three knees lost to natural cause (death), while 56 knees were available at þnal follow-up with their average of 20 years (19 to 24 years). The average age of follow-up was 65 years. 57 knees were done in male and 102 knees were in female. Revision surgery was carried out in 7 knees (4.4%). 90% of living patients were pain free. 90% had excellent knee score while only 10% had excellent function. 24 years survivorship was 89% (77 to 95%) for endpoint of revision surgery. Conclusions: Total Condylar knee arthroplasty provides excellent pain relief and knee score with only moderate improvement in the functional status. Total Condylar knee arthroplasty continues to be gold standard in total knee arthroplasty. This is longest reported results of Total Condylar knee arthroplasty.
