摘要：
According to one example, a tibial bearing component for articulation with a medial condyle and a lateral condyle of a femoral component in a knee replacement procedure is disclosed. The tibial bearing component can include a distal surface and an articular surface opposing the distal surface. The articular surface can include a medial compartment and a lateral compartment configured for articulation with the medial condyle and the lateral condyle of the femoral component, respectively. The lateral compartment can have a lateral articular track with a lateral anterior-posterior extent. The lateral articular track can comprise a plurality of distal-most points along a proximal surface of the lateral compartment that are contacted by the lateral condyle during rollback of the femoral component. The medial compartment can differ in configuration from the lateral compartment and can have an anterior lip height of between about 9 mm and about 13 mm.
