ABSTRACT:
A knee joint prosthesis includes a femoral component, a tibial plateau, and a tibial bearing member. The design and geometry of the articulation surfaces of the condylar elements of the femoral component and tibial bearing member is such that contact area between the articulation surfaces is maximized during flexion of the prosthesis. This is achieved by increasing the coronal radius of the bearing surfaces of the femoral component in the anterior to posterior direction along the bearing surface, i.e., increasing the coronal radius of the bearing surfaces of the femoral component as the femoral component transitions from extension to flexion.
