ABSTRACT:
A method and apparatus for arthroscopic unicompartmental knee surgery which include a femoral component and a tibial component. The femoral component is installed in a trough in the femoral condyle formed by using a template, a plurality of drill pins and a plurality of corresponding cutters. The template is aligned with the curvature of the femoral condyle, the two drill pins are passed through the template and drilled into the femur, cutters are advanced over the corresponding drill pins to make holes in the femur, and the remaining hourglass shaped bone is removed with osteotomy pliers to form the trough. A tibial socket for the tibial component is formed in a retrograde manner.
