Freehand Positioning of the Tibial

left/right tibial adjustment mechanism.
4. Lock the tibial cut guide by hand tightening the
blue screw on the tibial adjustment mechanism.
Tibial Registration
1. Position the tibial adjustment mechanism so that
the concave shape at the rear of the instrument
hugs the convex ridge of the tibial tubercle. Ensure
the position is low enough for the tibial cut guide
to attain the desired level of resection.
Note: As the tubercle may be obscured by the
tibial adjustment mechanism, the medial third
of the tubercle can be marked with a surgical
marking pen in order to ease the rotational
alignment of the tibial alignment guide later on.

Tibial Registration
2. Visually align the tibial adjustment mechanism in
varus/valgus and in flexion/extension by aligning
the elevator rod of the tibial cut guide parallel to
the tibial mechanical axis in both the frontal and
sagittal planes.
