An alignment guide for positioning a saw guide at a predetermined position on the distal femur is placed on the femur and receives an intramedullary rod inserted in the femur. The guide has an arm for coupling the saw guide block. The guide includes an intercondylar saddle that engages the intercondylar notch of the femur to align the saw guide at a predetermined position proximal to the intercondylar notch.

Alignment guide for a bone cutting block

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.

Apparatus for sizing a femoral component

The invention relates to a method for reconstructing a femoral portion of a knee in a total knee replacement, the distal end of which has medial and lateral condyles and an intercondylar notch therebetween defining a distal patellar groove for the articulation of the patella with the femur during flexion of the knee. The method comprising the steps of:

Method for installing a femoral component

An acetabular cup inserting instrument comprises a first handle and a second handle extending therefrom. The second handle is selectively rotatable about the first handle and selectively lockable in a desired position with respect to the first handle.
