Paragraph Number

97

The tapered sides 1032, 1034 of the post 1030 may permit natural articulation of the CR femoral component 1114 with the PS insert 1012, which may not be achievable if the post 1030 were not tapered. For example, if the post 1030 had straight sides instead of tapered sides, the wider width of the post 1030 at the base of the post 1030 may interfere with the internal articulating surfaces 1170, 1172 of the condyles 1160, 1164. When the PS femoral component 1014 is coupled with the PS insert 1012 to form assembly 1010, as in FIG. 14 and 15, the circular shape of the post superior end 1040 in combination with the tapered medial and lateral surfaces 1032, 1034 of the post 1030, may permit the PS femoral component 1014 to articulate relative to the PS insert 1012 in the manner of a posterior stabilized femoral component. However, when the PS insert 1012 is paired and implanted with the CR femoral component 1114, the resultant assembly 1110 may provide the native articulation and rotation of a cruciate retaining implant.
