Patent ID: 8398715

Claim:
A knee prosthesis comprising a femoral component configured to fit on a distal end of a resected femur, the femoral component comprising: an anterior portion comprising (i) an anterior portion planar interior surface configured to interface with the resected femur and (ii) an anterior portion exterior surface opposite the anterior portion planar interior surface, the anterior portion exterior surface including a trochlear groove; a lateral condyle section comprising a posterior portion which in turn comprises (i) a lateral condyle section posterior portion planar interior surface configured to interface with the resected femur and (ii) a lateral condyle section posterior portion exterior surface opposite the lateral condyle section posterior portion planar interior surface, the lateral condyle section posterior portion exterior surface comprising a posterior-lateral articular surface; and a medial condyle section comprising (i) a posterior portion which in turn comprises a medial condyle section posterior portion planar interior surface configured to interface with the resected femur and (ii) a medial condyle section posterior portion exterior surface opposite the medial condyle section posterior portion planar interior surface, the medial condyle section posterior portion exterior surface comprising a posterior-medial articular surface; wherein a plane formed by the anterior portion planar interior surface converges proximally with a plane formed by the lateral condyle section posterior portion planar interior surface or a plane formed by the medial condyle section posterior portion planar interior surface.
