Femoral Preparation

A-P Femoral Resections

1. Choose the correct size A-P cutting block and place it on the distal femur in a medialized position. The block is designed to allow for angling of the saw blade during the cuts. (Figure 12)
2. Secure the A-P cutting block first with a straight pin through either the medial, lateral or central pinhole in the distal block surface.Pin through the angled holes in the ears on the medial and lateral sides of the block as bone quality dictates to achieve stability. (Figure 13)

Note: The A-P cutting block should seat flush with the cut anterior and distal surfaces.

3. Complete the anterior, posterior and chamfer cuts. While cutting the posterior condyles, a thin bent Hohmann is placed beneath the MCL for retraction and for protection of the MCL.

Note: If it is preferable to resect the chamfers over a block rather than through slots, a chamfer cutting block is available. To align the chamfer block on the distal femur, drill 1/8" pins through the medial and lateral holes in the distal surface of the A-P cutting blocks. These are used for the spikes on the primary chamfer cutting blocks.
