Patent ID: 8506571

Claim:
A system for enhancing a surgical procedure on a knee, the system comprising: a femoral adjustment member removably engageable with a cut distal end of a femur, the femoral adjustment member comprising: a femoral body having a lateral side and a medial side; a lateral adjustable member disposed on the lateral side of the femoral body; and a medial adjustable member disposed on the medial side of the femoral body, wherein the lateral adjustable member and medial adjustable member are separately adjustable to adjust the position of the femoral body relative to the cut distal end of the femur and to apply tension to at least one of the lateral collateral ligament or the medial collateral ligament of the knee, and wherein the lateral adjustable member comprises a lateral adjustment element and a lateral paddle, the medial adjustable member comprises a medial adjustment element and a medial paddle; and a self-centering sliding mechanism disposed on the femoral body closer to the medial side than to the lateral side, the sliding mechanism configured to slide over an intramedullary rod extending from the cut end of the distal femur and to position the femoral body about the cut end of the distal femur, wherein the sliding mechanism comprises: a slider frame that rotates about a first axis defined by a slider holder connecting the slider frame to the femoral body and about a second axis defined by a longitudinal center of the slider frame; and a slider bolt that slides up and down the slider frame.
