Differences between native and prosthetic knees in terms of cross-sectional morphology of the femoral trochlea: A study based on three-dimensional models and virtual total knee arthroplasty

The cross-sectional morphology of the prosthetic knee is crucial to understanding patellar motion and quadriceps strength after total knee arthroplasty. However, few comparative evaluations of the cross-sectional morphology of the femoral trochlea have been performed in the native knee and currently available femoral implants.
