Warning: Ensure to hold the Tibial Adjustment
Mechanism while removing the 3.5 x 38 mm
Hex Head Screws from it. Make sure to remove
those screws in the angular orientation of the
initial hole. Removing the last scew that was
put in rst (rst screw in, last screw out) can
help to keep the right orientation.
Note: If the proximal tibial cut needs to
be corrected, it is possible to navigate the
orientation of the Cut Guide in order to execute
the cut again. To do so: 1. Remove the “Cut
Guide” Pod attached to the Validation Tool
and clip it to the front receptacle of the Tibial
Adjustment Mechanism. 2. Press the “Z” button
on the pod attached to the front receptacle of
the tibial adjustment mechanism. 3. Follow
feedback (red and green LEDs) on the pod
attached to the tibial adjustment mechanism
and adjust tibia slope and varus/valgus using
the gold and green screws respectively.
10. Remove the 3.2 mm Headless Trocar Drill Pins,
the Tibial Cut Guide, the 3.5 x 38 mm Hex Head
Screws and the Tibial Adjustment Mechanism.
11. Proceed with the femur registration if continuing
with the distal femur cut. Refer to the Workow
Selection section for more details.
