A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medal anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.

Distal femoral cutting guide

A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medial anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.

A system locates a femoral cutting guide on a distal end of a femur. The femoral cutting guide establishes at least a first reference plane to perform a distal femoral planar cut. The system generally includes a mounting rod operable to insert into the distal end of the femur. An index member is operable to abut the distal end of the femur. A bridge member extends from the index member. A cutting guide member extends from the bridge member. The cutting guide member includes a first channel that establishes the first reference plane. A mounting mechanism releasably couples the cutting guide member to the bridge member. The mounting mechanism is operable to generate a sliding resistance between the bridge member and the cutting guide member that is generally overcome to position the cutting guide member relative to the femur.
