We prospectively enrolled 118 patients (133 knees) whose arthroplasties were performed using posterior-stabilized rotating-platform knee implants. Introduced in year 2000, this implant's performance beyond 5 years is not reported on, to date. We present 5- to 8-year (average, 6.5 years) results of 118 posterior-stabilized rotating-platform knee arthroplasties. Kaplan-Meier survival rate was 100%, considering revision or the need for it as the end point. Mean Knee Society Score improved from 27 (range, 1-54) to 96 (range, 54-100). Mean function score improved from 51 (range, 5-81) to 83 (range, 0-100). No patient had spin-out of rotating bearing or osteolysis. Postoperatively, knee flexion averaged 120° (range, 80°-155°), 34% patients achieved more than 130° flexion, and 67% patients could sit cross legged. Only 5% patients presented with patellofemoral symptoms.
