Abstract
A knee prosthesis has a femoral component with a medial condyle defining a constant bearing spacing relative to a central sagittal component plane SP, and a lateral condyle defining divergent bearing spacing from the central sagittal component plane along an extension-to-flexion path. High congruence between the medial articulation surfaces creates a pivot point for external rotation at the medial contact area, while lower congruence in the lateral articulation surfaces allows the lateral femoral condyle to track anteriorly and posteriorly during flexion. The amount of lateral condyle bearing spacing divergence is calculated to produce a substantially linear anteroposterior motion profile of the lateral femoral condyle upon the lateral tibia articular surface throughout a wide range of flexion.
