The ZUK Unicompartmental High Flex
Knee System has been designed for
5° of posterior tibial slope. The angle
on the handle of the Spacer Block is
angled 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 Distal Femoral Resector
over the handle of the Spacer Block
(Fig. 5). Then secure the guide by
inserting a 48mm Headed Screw
or predrill and insert a Holding Pin
through the hole (Fig. 6).
Use a 1.27mm (0.050-inch) oscillating
saw blade to resect the distal femur
(Fig. 7). Do not extend the saw blade
posteriorly past the distal femur to
avoid damaging the posterior popliteal
area. If desired, the femoral cut can
be started in extension and finished
in flexion. Before flexing the knee,
remove the Distal Femoral Resector
and Spacer Block. Then return to
Check Flexion/Extension Gaps (Step 4)
in the IM surgical technique.
