Survival analysis of cemented Press-Fit Condylar total knee arthroplasty

Abstract

We performed a survival analysis on 354 cemented primary Press-Fit Condylar (PFC) total knee arthroplasties (TKA) in 277 patients with prospective follow-up (mean, 6 years; range, 2-11.7 years). No patient was lost to follow-up. Using revision for all causes as the endpoint, the cumulative survival rate at 10 years was 95.5% (95% confidence interval, 90.1%-98.1%). The 10-year clinical outcome available on 41 patients was good, with significant improvement in pain and mobility assessments using the Nottingham data collection system. Our results indicate that the cemented PFC TKA has good long-term survival based on revision as the endpoint. Revision for implant failure is rare and brings to question modifications to this prosthesis.
