Femoral Preparation

Preliminary Anterior Femoral Resection

1. Secure the valgus alignment guide using the floating pins.
2. Release and remove the modular paddles.
3. Decrease knee flexion to 70-90°. (This allows the soft tissue window to be moved proximally for referencing of the anterior femoral cortex.)
4. Place the anterior resection guide into the valgus alignment guide and attach the anterior stylus to the anterior resection guide by sliding the foot into the cutting slot. Place the stylus tip on the lateral ridge of the anterior femoral cortex. (Figure 7)

Note: The stylus is designed to insert the tip under the skin if necessary. The skin can be retracted to aid in placement of the stylus.

5. Pin the anterior resection guide with a 1/8" trocar pin and remove the anterior stylus.
6. Resect the anterior cortex. (Figure 8)

Note: When making this cut, a retractor is used to retract the skin upward while the cut is made (the saw blade will cut under the skin).
