PHYSICA ZUK SURGICAL TECHNIQUE Step 2 | Distal Femoral Resection
STEP 2 DISTAL FEMORAL RESECTION
After resecting the proximal tibia, bring the knee into full extension. Insert the 8 mm Spacer Block into the joint space until the anterior stop contacts the anterior tibia in order to assess the gap. (Fig. 19) The Spacer Block must be fully inserted and sit flat on the resected tibial surface to ensure that the proper amount of distal femoral bone will be resected. If the 8 mm Spacer Block is too tight, remove an additional 2 mm from the proximal tibia with the Tibial Cutting Block by using the +2mm holes. If the 8 mm Spacer Block is too loose, use a thicker Spacer Block. The Spacer Blocks are available in 8 mm, 9 mm, 10 mm, 11 mm, 12 mm and 14 mm thicknesses. If necessary, for additional stability, insert a 35 mm headed screw into the anteromedial angled hole in the Spacer Block. The Physica ZUK System has been designed for 5° of posterior tibial slope. The angle on the handle of the Spacer Block is angled at 5° relative to the Spacer Block. This ensures that the distal femoral resection is made perpendicular to the long axis of the femur. Place the Spacer Block Distal Femoral Resector over the handle of the Spacer Block. (Fig. 20) Check the alignment by inserting the Alignment Tower into the sawblade slot. (Fig. 21)
