SYSTEMS AND METHODS FOR PROVIDING A FEMORAL COMPONENT

摘要

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a femoral knee replacement component that includes an articular surface, a first interior surface, and a second interior surface, wherein the first and second interior surfaces run substantially parallel to each other. In some cases, the articular surface includes an anterior condylar extension that is configured to replace an anterior articular cartilage of a femur such that the anterior extension is configured to terminate adjacent to a proximal limit of the anterior articular cartilage of the femur. Other implementations are also discussed.

1. A method for normalizing patellar tracking and patello-femoral forces within a knee during deep flexion, the method comprising:
preparing a femur to receive the femoral component by resecting bone and articular cartilage from a distal portion of the femur, wherein the articular cartilage and bone is removed from an antero-proximal portion of the femur's anterior condyles to within about 0 mm and about 15 mm of a proximal limit of the articular cartilage; positioning the femoral component onto the resectioned surfaces of the femur so that an anterior-most extension of the femoral component terminates within about 15 mm of the proximal limit; and securing the femoral component to the prepared femur.
