Posterior cruciate-retaining modular total knee arthroplasty - A 9- to 12-year follow-up investigation

Between November 1988 and January 1991, 101 press-fit condylar (PFC; Johnson & Johnson, Raynham, MA) posterior cruciate-retaining total knee arthroplasties were performed in 75 patients. All tibial components were modular metal-backed, and all patellar components were all-polyethylene. All living patients were evaluated at an average 10.5 years (range, 9.5-11.8 years). Only I knee required revision (at 11. 1 years after the procedure), and only 1 other knee had evidence of radiographic failure. The average range of motion was V (range, 0degrees-10degrees) to 110degrees (range, 86degrees-130degrees). At 10 years of follow-up, the probability of prosthesis survival was 100%, and at 12 years, the probability of prosthesis survival was 93.3% (endpoint defined as revision for any reason).
