2 A. Femoral Preparation A.1. Pilot Hole With the ACL removed, the typical femoral entry hole location is thought to be slightly medial to the center of the intercondylar notch, and approximately 5 to 7 mm anterior to the anterior insertion of the PCL into the femur. Important note: As both varus and valgus deformities are commonly encountered in the Patient who receives Total knee arthroplasty, careful evaluation of the possible A-P and M-L curvature of the femoral shaft should be undertaken to consider shifting the initial entry hole to a more appropriate location for each patient. A Starter 1 is used to mark the hole location, followed by the 8mm Twist Drill 2 to create an opening in the femoral canal. The drill is typically inserted to a depth of approximately 100mm within the femoral canal. After removal of the drill, intramedullary fluid of the femur may be reduced by inserting the small diameter Alignment Rod 3 into the femoral shaft several times. This will also identify the femoral canal. Once the canal is identified, the Femoral IM Rod 4 and T-Handle 5 is manually inserted into the femoral canal until the isthmus is engaged. Care should be taken when encountering the isthmus and make sure the rod can be completely pass through. Please note: If the canal isthmus diameter is thought to be too narrow for standard passage of the rod, advancement is discontinued, and an intraoperative radiograph may be employed to access the appropriate location of the rod. 1 Starter 9301-2101-RB 3 Alignment Rod 9403-2202 4 Femoral IM Rod 9303-3200,(400 mm) 2 8mm Twist Drill 9301-3201 5 T-Handle 9301-1100
