Posterior crutiate-retaining orthopaedic knee prosthesis having controlled condylar curvature

摘要

An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature may be increased during mid-flexion. 06/10/15jm18077 amended specidocx,41
