摘要：

Paradoxical anterior movement of the femoral condyles after total knee arthroplasty (TKA) often attenuates the extension mechanism and causes a suboptimal outcome. The medial-pivot implant design aimed to confine anterior movement and emulate physiologic knee kinematics. In our study, a consecutive series of 58 medial-pivot TKA were enrolled with a minimum 5-year follow-up. The Knee Society score improved from 30.5 to 91.1 in objective and from 36.7 to 82.3 in functional scale. The average range of motion was 115.4 degrees. The medial-pivot TKA provided significant improvement in the postoperative range of motion, objective Knee Society score, pain scale, and functional score (P < .05) statistically. A larger sample and longer follow-up are recommended to draw definitive conclusions of this new implant design.
