Referring to FIG. 16C, the boundary of the superior end 1040 may define a rounded rim 1044 shaped as a portion of a circle defined by a circular envelope 1047, as seen from a superior perspective. The superior end 1040 and rim 1044 may have a convex protrusion 1041 toward a posterior end of the post 1030 as shown and may permit passage of the posterior cruciate ligament. The circular superior end 1040 with rim 1044 may provide increased rotational range of motion and surface contact against the femoral component 1014 in comparison to traditional posts with a more square or rectangular shape and no rim. Thus, the rounded superior end 1040 and rim 1044 may allow for greater surface contact with the femoral component 1014 in contrast to the mere point or edge contact that is achieved by traditional posts that do not have these features.
