Summary

The "ball-in-socket" design of the Medial-Pivot knee system (MicroPort Orthopedics, Arling-ton, Tennessee, USA) aims to reproduce normal knee kinematics by medializing its rotational axis. Thegoal of this study was to measure knee range of motion (ROM) with this implant after a mean follow-up of 10 years and to report the survivorship and long-term clinical and radiological outcomes. Wehypothesized the prosthetic knee would have at least 120◦flexion at 10 years. This was retrospective, single-centre study of 74 Medial-Pivot knees implanted in71 patients (average age of 69 years) between May 2005 and November 2007. All patients who receiveda Medial-Pivot knee were included consecutively. The mean follow-up was 10 years. Clinical and radio-logical assessments were performed using the Knee Society Score (KSS) and Ewald's score. Kaplan-Meirsurvival analysis was used to calculate survivorship.
