In FIG. 28A, the lateral tibial compartment 2814 and/or medial tibial compartment 2813 are configured such that the longitudinal axis 2846 for tibiofemoral rotation is within the medial tibial compartment 2813. In FIG. 24A, the lateral tibial compartment 2814 and/or medial tibial compartment 2813 are configured such that the longitudinal axis 2446 is within a medial tibial compartment, which may be generally defined by the medial articulation surface 2420. Knee assemblies that are configured, designed, and/or engineered for tibiofemoral rotation is within the lateral tibial compartment 2814 may be referred to as lateral pivot design knee assemblies. Knee assemblies that are configured, designed, and/or engineered for tibiofemoral rotation is within the medial tibial compartment may be referred to as medial pivot design knee assemblies. With certain patients it may be desirable to use a lateral pivot design knee assembly in a left knee and a medial pivot design knee assembly in a right knee. Alternatively, or in addition, it may be desirable to use a medial pivot design knee assembly in a left knee and a lateral pivot design knee assembly in a right knee. Alternatively, or in addition, it may be desirable to use a lateral pivot design knee assembly or a medial pivot design knee assembly in either or both of a left knee and a right knee.
