Abstract:
1. A knee prosthesis comprising: (a) a femoral component configured to fit on a distal end of a femur, the femoral component comprising an anterior portion, a posterior portion, and a distal portion connecting the anterior portion to the posterior portion, wherein the distal portion includes a continuously convexly curved medial articular portion extending from the anterior portion to the posterior portion and a continuously convexly curved lateral articular portion extending from the anterior portion to the posterior portion, (b) a tibial articular component configured to fit on a proximal end of a tibial, the tibial articular component comprising a medial articular surface for articulating with the medial articular portion of the femoral component, and a lateral articular surface for articulating with the lateral articular portion of the femoral component; wherein the medial articular portion of the femoral component protrudes further distally than the lateral articular portion of the femoral component, and wherein the posterior portion of the femoral component comprises a posterior medial articular portion and a posterior lateral articular portion, wherein the posterior medial articular portion protrudes further in a posterior direction than the posterior lateral articular portion.
