The PS femoral component 14 depicted in FIGS. 1-8 may include a cam element or cam bar 50 and a box structure 52 for providing posterior stabilization in place of absent ligaments. The cam bar 50 may include a cam articulating surface 51 which may contact the posterior articulation surface 42 of the post 30 during flexion, as in FIGS. 1B and 7. An internal articulation surface 54 may reside on the inside of the box structure 52 and may contact the post 30 during articulation and rotation of the knee joint. The internal articulating surface 54 may be concavely curved and may contact the rim 44 of the post 30 during axial rotation of the knee joint about the post. The PS femoral component 14 may further include a medial condyle 60 having a medial condylar articulation surface 62, and a lateral condyle 64 having a lateral condylar articulation surface 66. The medial and lateral condylar articulation surfaces 62, 66 may articulate against the PS insert 12 medial and lateral condylar articulation surfaces 25, 27, respectively. A gap 68 may be formed between the medial and lateral condyles 60, 64, with the cam bar 50 extending medial-laterally across the gap 68. The internal articulation surface 54 may include a medial portion 70 continuous with a lateral portion 72. In the embodiment depicted, a fixation post 74 may protrude superiorly from the PS femoral component 14. However, in other embodiments of the PS femoral component 14, the fixation post 74 may be absent and/or other fixation features such as posts, spikes, pegs, webs, keels, or teeth may be present to affix the PS femoral component 14 to a prepared femur (not shown).

Referring to FIG. 3C, the boundary of the post superior end 40 defines a rounded rim 44 shaped as a portion of a circle defined by a circular envelope 47, as seen from a superior perspective. The post superior end 40 and rim 44 may be crescent-shaped with a concave recess toward a posterior end of the post 30 as shown and may permit passage of the posterior cruciate ligament. The post superior end 40 may be circular; the rim 44 may provide increased rotational range of motion and surface contact against the femoral component 14 in comparison to traditional posts with a more square or rectangular shape and no rim. Thus, the rounded post superior end 40 and rim 44 may allow for surface contact with the femoral component 14 in contrast to the mere point or edge contact that is achieved by traditional posts that do not have these features.

The articulation surface 31 may include a medial articulation surface 32, a lateral articulation surface 34, an anterior post surface 36, and a posterior articulation surface 42. The medial and lateral articulation surfaces 32, 34 may be non-parallel to one another and taper inward from the post superior end 40 to the post base 38 relative to an insert midline vertical axis 2, as shown in FIGS. 3A and 3B. As shown in FIG. 3A, an angle θ between the vertical axis 2 and each tapered surface 32, 34 may be about 6.5°, in at least one embodiment. Since the post 30 may be bilaterally symmetrical, the angle θ may be the same on both the medial and lateral articulation surfaces 32, 34 of the post 30. In other embodiments of the disclosure, angle θ may range from about 6° to 11° degrees. The medial articulation surface 32 may be continuous with the medial condylar articulation surface 25, and the lateral articulation surface 34 may be continuous with the lateral condylar articulation surface 27, as can been further seen in cross-section in FIGS. 6 and 8. The anterior post surface 36 may extend between the medial and lateral articulation surfaces 32, 34 and may be convexly rounded. The anterior post surface 36 may also taper outward from the post superior end 40 to the post base 38 relative to the midline vertical axis 2, as best seen in FIG. 3D. In other embodiments of the PS insert 12, the anterior post surface 36 may include less or no taper.
