Abstract
Instrumentation for surgically resurfacing a femoral condyle to receive a prosthetic femoral component in minimally invasive unicompartmental knee replacement surgery. The instrumentation includes a resurfacing guide for attachment to a femur and a rail member externally delineating an area of a femoral condyle of the femur that is to be surgically resurfaced to receive a prosthetic femoral component. The resurfacing guide has an abutment wall. The instrumentation includes a resurfacing instrument having a tissue removing surface for removing anatomical tissue from the delineated area of the femoral condyle, the tissue removing surface being movable along the delineated area to remove anatomical tissue therefrom. The resurfacing instrument has a engagement wall for contacting the abutment wall to limit the depth to which anatomical tissue is removed.
