The purpose

The purpose of this study is to investigate whether subjects receiving a high-flexion knee prosthesis show a better knee function than patients receiving a standard knee prosthesis. Thigh-calf contact force measurements are used to quantify knee function. The investigators' hypothesis is that high-flexion knees show a better knee function.
