Systems and methods for providing an asymmetrical femoral component

摘要

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include an asymmetrical femoral component that includes a femoral prosthesis that is configured to attach to a distal portion of a femur. In some such instances, the prosthesis includes a medial condyle and a lateral condyle, wherein a medial-lateral width of an articulation surface of the lateral condyle is approximately 75% or less of a medial-lateral width of an articulation surface of the medial condyle. Other implementations are also discussed.

主权项

1. An asymmetrical femoral component, comprising:
a femoral prosthesis configured to attach to a distal portion of a femur, the prosthesis comprising:
a medial condyle;a lateral condyle;a patellar groove; anda concave articulation surface that is configured to articulate against a portion of at least one of a tibia and a tibial component when the prosthesis is seated in a knee joint, wherein the patellar groove extends laterally at an angle from a distal posterior portion of the patellar groove to a distal anterior portion of the patellar groove and to proximal anterior portion of the patellar groove, wherein the concave articulation surface is defined in an exterior surface of at least one of the medial condyle and the lateral condyle, wherein a portion of the concave articulation surface is disposed at least one of lateral and medial to the patellar groove, and wherein the portion of the concave articulation surface is disposed posterior to a distal-most portion of the femoral prosthesis.
