PHYSICA ZUK SURGICAL TECHNIQUE Step 1 | Proximal Tibial Resection
The depth of cut can be verified by using the feeler blade. Use a 1.27 mm (0.050-inch) oscillating sawblade through the slot in the cutting guide to make the transverse cut. The Tibial Cutting Block must remain against the bone during resection. TECHNIQUE TIP. Insert a retractor medially to protect the medial collateral ligament. With the knee flexed, use the reciprocating saw at the base of the tibial eminence and parallel to the eminence in the A/P plane to perform the sagittal L-cut. Cut along the edge of the ACL down to, but not beyond, the intended level of the transverse cut. (Fig. 15) Be careful to avoid the ACL attachment. Perform the horizontal cut. (Fig. 16) After both tibial cuts are performed, remove the EM Tibial Guide assembly. (Fig. 17)

TECHNIQUE TIP. You can use the rasp to refine the edge between the proximal and sagittal cut.
NOTE: Aternatively to the above mentioned + 2mm recut technique, a specific instrument for recutting is available [9061.10.002]. Remove the tibial cutting block and the EM guide leaving in place the two headless pins. Insert the recutter [9061.10.002] over the two pins and proceed with recutting of the tibia. (Fig. 18)
