Summary

Numerous studies have echoed the superior clinical outcomes of posterior-stabilized (PS) total knee arthroplasty compared to posterior cruciate-retaining (CR) total knee arthroplasty. The post-cam mechanism of posterior-stabilized (PS) total knee arthroplasty has been postulated to provide reproducible femoral rollback and increased flexion. However, posterior-stabilized (PS) total knee arthroplasty systems are purportedly limited due to several post-cam related problems, including post-cam dislocation, wear and breakage of post, and patellar clunk syndrome. Moreover, the post-cam mechanism requires additional bone resection and poses a risk for intercondylar fracture of the distal femur during box preparation. To overcome these issues, a fixed-bearing highly conforming ultra-congruent (UC) total knee arthroplasty was introduced.

This study aims to compare the clinical results of Ultra-Congruent(UC) and posterior-stabilized(PS) insert in bilateral total knee arthroplasty.
