Knee implant
First Claim
1. A method of implanting a prosthetic device comprising the steps of:
- selecting a first side femoral component configured to be implanted on at least one of a lateral condyle and a medial condyle of a femur;
implanting the first side femoral component on one of the lateral condyle and the medial condyle of the femur;
selecting a second side femoral component configured to be implanted on at least the other of the lateral condyle and the medial condyle of the femur, wherein the second side femoral component is selected from a plurality of femoral components configured to be used with the first side femoral component based on characteristics of the second side femoral component; and
implanting the second side femoral component on the femur.

Abstract
A modular prosthetic device is provided for replacement of the knee. The device is assembled from a plurality of components, each of which can be inserted through a small incision. After inserting the components through the incision, the device can be assembled within the knee cavity. The modularity of the device enables a surgeon to replace only those regions of the knee that are diseased or damaged, thereby avoiding a complete knee replacement. If, at a later time, additional regions of the knee become diseased or damaged, those additional regions of the knee can be replaced by additional device components and those additional components can be connected to the previously implanted components. By replacing only those regions of the knee that are diseased or damaged and by implanting each of the components through the small incision, the surgery is minimally invasive and, therefore, requires reduced time for healing and rehabilitation.
