We prospectively enrolled 48 patients (53 knees), scheduled for high-flex posterior-stabilized rotating platform knee implant arthroplasty (PFCΣRPF) to our study. Performance of this implant, introduced in 2005, has been reported upon only up to 2 years. We report its 2- to 6-year postoperative clinical and radiographic results in 47 patients (52 knees). Mean Knee Society score improved from 35.7 to 96. Mean function score improved from 55.2 to 90.6. Postoperative knee flexion averaged 130° (95°-155°), 81% patients could sit cross legged, 53% could sit on floor, and 21% could squat. Kaplan-Meier survival rate was 100% at average 50.2 months (26-72 months). No patient had any spin-out of rotating bearing. Supervised radiographs were analyzed, which showed no osteolysis or component loosening.
