Claim 19:
20. A femoral component for a knee prosthesis, comprising:
an anterior flange;
a medial condyle extending from the anterior flange to a posterior end thereof and having inner and outer edges defining a medial condyle width therebetween, the inner edge lying substantially along a single plane from the anterior flange to the posterior end of the medial condyle; and
a lateral condyle extending from the anterior flange to a posterior end thereof and having inner and outer edges defining a lateral condyle width therebetween, the inner edge of the lateral condyle having a first portion, a second portion, and an intermediate portion,
wherein the inner edges of the lateral and medial condyles define an intercondylar notch and lateral and medial extents of the intercondylar notch such that an intercondylar width extends between the inner edges of the lateral and medial condyles,
wherein the inner edge of the lateral condyle tapers toward the outer edge of the lateral condyle at the intermediate portion such that the intercondylar width is greater along the second portion of the inner edge of the lateral condyle than along the first portion of the lateral condyle,
wherein the femoral component includes a bone contacting side having a plurality of planar bone contacting surfaces comprised of an anterior surface, a distal surface, a posterior surface, an anterior chamfer surface, and a posterior chamfer surface, the anterior chamfer surface being disposed between the anterior surface and distal surface, the posterior chamfer surface being disposed between the distal surface and posterior surface, and
wherein the intermediate portion of the inner edge of the lateral condyle is intersected by the posterior chamfer surface.
