Abstract
From 1975 to 1983, 278 patients received 418 posterior cruciate ligament-retaining Total Condylar knee arthroplasties. Twenty-four patients were excluded, 15 for lack of followup data, 6 for infection during followup, and 3 for revision surgeries for previous infections. The 394 remaining knees were observed from 1 to 18 years (mean, 8.08 years). Kaplan-Meier and crude survival estimates at 12 years were 96.8% and 98.1%, respectively. Various survival analyses by other authors have yielded similar successful results.
