ABSTRACT:
An alignment guide comprises a guide block locator having surfaces for engaging a prepared femur and establishing a specific position relative to an intercondylar slot in the femur. The guide block locator contains an aperture for directing a guide block to the specific position. The guide block includes a leg that can be driven into the femur to hold the guide block in place. The guide block is adapted to precisely engage the cam box of a femoral implant. Upon removal of the guide block locator, the femoral implant can be positioned over the guide block where the cam box will engage the guide block before the anterior and posterior flanges of the implant grip the anterior and posterior surfaces of the femur thereby providing proper alignment of the femur and implant.
