Abstract:
Between 1975 and 1983, 280 patients received 422 posterior cruciate ligament-retaining total condylar knee arthroplasties. Fifty-nine were excluded for one of the following reasons: previous total knee replacement, follow-up less than 1 year, or infection at any time during the life of the prosthesis. The 363 remaining knees were observed from 1 to 13 years (mean, 6.86). Kaplan-Meier and "crude" survival estimates at 12 years were 94.7% and 96.6%, respectively. Results of various survival analyses by other authors yield similar successful results.
