Paragraph Number

137

In certain embodiments, the assembly 2800 may include a longitudinal axis 2846. The longitudinal axis 2846 may generally indicate an area or vicinity where a condyle articulation surface rotates during tibiofemoral rotation that occurs during arthrosis (joint) flexion. The present disclosure supports one or more embodiments of a knee assembly, for example assembly 2800, that enables, facilitates, and/or provides for tibiofemoral rotation about a longitudinal axis within a medial tibial compartment 2813 (as shown by longitudinal axis 2846 in FIG. 28A). Alternatively, or in addition, tibiofemoral rotation may be about a longitudinal axis within a lateral tibial compartment 2814. In certain embodiments, the shape and/or contour of a lateral articulation surface and/or a medial articulation surface can influence whether the longitudinal axis is within the lateral tibial compartment (generally defined by the lateral articulation surface) or the medial tibial compartment (generally defined by the medial articulation surface).
