Long-Term Comparison of Fixed- and Mobile-Bearing Total Knee Arthroplasties (TKAs) in Patients With OA ≤50 Years Old

Ewha Womans University216 enrolled

Overview

The purpose of the prospective study was to evaluate the minimum fifteen year follow-up of prospective total knee arthroplasties performed in patients younger than fifty years of age with osteoarthritis, using fixed- and mobile-bearing knee prostheses in the same patients, to compare 1. functional scores 2. rates of radiographic failure 3. revision rates 4. survivorship

The randomized prospective comparison of fixed- and mobile-bearing total knee designs in the same patients younger than fifty years of age is limited. The purpose of this study was to compare the long-term clinical and radiographic results of fixed- and mobile-bearing total knee arthroplasties in patients younger than fifty years of age with osteoarthritis.
