Patent ID: 8647389

Claim:
A knee prosthesis, comprising: a. a femoral component configured to fit on a distal end of a femur, the femoral component comprising a medial condyle and a lateral condyle segment wherein the medial condyle comprises an anterior-medial condyle segment, a posterior-medial condyle segment and a distal-medial condyle segment connecting the anterior-medial condyle segment to the posterior-medial condyle segment, wherein the distal-medial condyle segment is continuously convexly curved between the anterior-medial condyle segment and the posterior-medial condyle segment; wherein the lateral condyle comprises an anterior-lateral condyle segment, a posterior-lateral condyle segment, and a distal-lateral condyle segment connecting the anterior-lateral condyle segment to the posterior-lateral condyle segment; the distal-medial condyle segment projecting further distally relative to the distal-lateral condyle segment; and b. a tibial component configured to fit on a proximal end of a tibia; wherein the femoral and tibial components are configured such that, a posterior-most extent of the medial condyle overhangs in a posterior direction a posterior-most extent of the tibial component, the overhang being approximately two millimeters, and a posterior-most extent of the lateral condyle does not extend further in the posterior direction than the posterior-most extent of the tibial component.
