Step 2 | Distal Femoral Resection
Use the alignment rods through the Alignment Tower to verify the alignment. Then secure the guide by inserting a 50 mm headed screw through the Distal Femoral Resector hole. (Fig. 22)
Use a 1.27 mm (0.050-inch) narrow oscillating saw blade to resect the distal femur. (Fig. 23)
TECHNIQUE TIP. To avoid that the distal femoral cut is done in pre-flexion, it can be helpful to check that the alignment rod is parallel to the femoral bone in the lateral view. ATTENTION. To avoid damaging the posterior popliteal area, do not extend the sawblade posteriorly past the distal femur USE OF FEMORAL SHIMS In case of excessive laxity in extension or excessive wear of the distal condyle, less distal bone should be resected. The use of shims should be carefully evaluated. The Spacer Block Femoral Shims can be added to each Spacer Block to cut less distal femoral bone. (Fig. 24)
Figure 22
Shims are available in 1 mm and 2 mm thicknesses.
TECHNIQUE TIP. When using the shims, please re-verify the correct alignment by using the alignment tower with the alignment rods a thinner spacer block may be needed.
