Claim:
A knee prosthesis comprising a femoral component, the femoral component comprising: (a) a lateral condyle; (b) a medial condyle; and (c) an anterior cam and a posterior cam, wherein both the anterior and posterior cams extend between the lateral condyle and the medial condyle in an intracondylar notch of the femoral component, and wherein the posterior cam includes a medial side and a lateral side, wherein the medial side is asymmetric with respect to the lateral side and wherein the lateral side of the posterior cam of the femoral component is larger than the medial side of the posterior cam, wherein a distal portion of an articular surface of the posterior cam curves in a proximal to distal direction as it extends from the medial condyle to the lateral condyle and wherein a posterior portion of the articular surface of the posterior cam curves in an anterior to posterior direction as it extends from the medial condyle to the lateral condyle.
