Paragraph Number

104

Referring to FIG. 22B, the boundary of the post superior end 1340 may define a rounded rim 1344 shaped as a portion of a circle, from a superior perspective, and may have a convex protrusion toward a posterior end of the post 1330. The post superior end 1340 and rim 1344 may be semi-circular as shown, however the rim 1344 may define a circular envelope 1347. The post superior end 1340 may be circular and the rim 1344 may provide increased surface contact and rotational range of motion when coupled and implanted with the PS femoral components disclosed herein in comparison to traditionally shaped posts with a more square or rectangular shaped post. Thus, the rounded post superior end 1340 and rim 1344 may allow for greater surface contact with the femoral components 14, 1014 in contrast to the mere point or edge contact that is achieved by traditional posts that do not include these features.
