ABSTRACT:
A sizing assembly for determining the optimum size of a femoral component of a knee prosthesis is placed against the resected distal end of a femur. The assembly includes a body with a flat surface for contacting the resected surface of the femur and feet for engaging the femoral condyles. The assembly further includes a pivoted stylus that slides in the body and engages the anterior femoral cortex. Once the size of the femoral component is determined, a drill bushing corresponding to the femoral component is supported on the body. The drill bushing includes two apertures for guiding a drill to bore pilot holes in the resected femur.
