Instrumentation for minimally invasive unicompartmental knee replacement

Instrumentation for surgically resurfacing a femoral condyle to receive a unicompartmental prosthetic femoral component in minimally invasive unicompartmental knee replacement surgery, said instrumentation comprising

• a resurfacing guide for attachment to a femur and comprising a rail member externally delineating an area of a femoral condyle of the femur that is to be surgically resurfaced to receive a unicompartmental prosthetic femoral component, said resurfacing guide having an abutment wall, said rail member of said resurfacing guide including a pair of legs, said legs curving posteriorly, posterior ends of said legs integrally connected by a transverse connecting pad, said connecting pad having a recessed surface configured for supporting a posterior resection block;
• and
• a resurfacing instrument having a tissue removing surface for removing anatomical tissue from the delineated area of the femoral condyle, said tissue removing surface being movable along the delineated area to remove anatomical tissue therefrom, said resurfacing instrument having an engagement wall for contacting said abutment wall to limit the depth to which anatomical tissue is removed.
