Patent ID: 7060074

Claim:
Instrumentation for surgically preparing a femoral condyle to receive a prosthetic femoral component in minimally invasive unicoinpartmental knee replacement surgery, said instrumentation comprising a resection block for fixation to a femur with the knee in flexion, said resection block having an anterior portion and an elongated base plate extending posteriorly from said anterior portion, said base plate having a cantilevered tongue configured to engage a recessed surface of a resurfacing guide, said anterior portion having a planar resection slot for receiving a cutting member to effect a planar surface along a posterior aspect of a fermoral condyle of the femur; and a resurfacing guide for fixation to the femur, said resurfacing guide including a rail member having a pair of legs, said legs curving in a posterior direction, posterior ends of said legs connected by a transverse connecting pad, said connecting pad having a recess configured to receive and support said cantelivered tongue of said resection block, an inside surface of said rail member providing an inside track for a femoral resurfacing instrument, said inside surface of said track sized and configured to externally delineate an area of the femoral condyle to be resurfaced by a resurfacing instrument, said resurfacing guide attachable to said resection block via said cantilevered tongue of said resection block and said recess of said resurfacing guide to form an assembly prior to fixation of said assembly to the femur.
