Abstract
The apparatus of the present invention includes a number of components including a guide body component, an extension block component, a rotating arm component, an extension rod component, and a tibial referencing component. The guide body component contacts the distal-most surface of the femur. Its location is based off of the posterior femoral condyles and the surface of the distal-most femoral resection or the unresected distal-most femoral surface. The rotating arm component is interconnected with the guide body and may rotate with respect thereto, thus allowing for the direct or indirect adjustment of the rotating alignment of cutting guides for resecting the distal femur. The rotating arm component carries arms with drill screw apertures which direct placement of drill holes in the femur which are used to attach a cutting guide to the femur. The rotating arm component is attached to the extension rod component which extends to the tibial referencing component which references the location and orientation of the proximal resected surface of the tibia. Thus the rotating alignment of the distal femoral prosthesis is established with respect to the orientation of the resected proximal tibial surface.
