Outcomes After Standard and High-Flexion Posterior Stabilized Rotating-Platform Mobile-Bearing Total Knee Arthroplasty

The aim of this prospective study is to compare the clinical and radiographic outcomes of standard and high-flexion posterior stabilized (PS) rotating-platform mobile-bearing (RP-MB) total knee arthroplasty. The investigators hypothesize that total knee arthroplasty performed with a high-flexion PS RP-MB design would improve range of motion, and that this would be reflected by a better clinical outcome and greater patient satisfaction.
