Systems and methods for providing a femoral component with a modified posterior condyle

摘要

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a knee prosthesis that includes a femoral component for replacing at least a portion of a distal end of a femur. In some cases, the femoral component has a posterior condyle that is configured to articulate against a tibial articular surface. In such cases, an articular surface at a proximal portion of the posterior condyle is sized and shaped to extend at least half of an antero-posterior distance between a most posterior portion of the posterior condyle and a plane that is a continuation of a distal one fourth to one third of a posterior cortex of a femoral shaft of the femur. Other implementations are also discussed.

主权项

1. A knee prosthesis comprising:
a femoral component for replacing at least a portion of a distal end of a femur, the femoral component comprising:
at least a portion of a posterior condyle,an interior surface configured to face a resected surface of the distal end of the femur, and a projection providing an articular surface at a proximal portion of the posterior condyle, wherein the projection extends, at least partially, anteriorly away from the interior surface.
