Tibial Workow Selection
1. Place the pegs of the Tibial Aligner on the proximal
tibial plateau and sit the Tibial Adjustment
Mechanism on the anterior cortex of the tibia.
2. Preset the height of the Tibial Adjustment
Mechanism by moving the lower part of the Tibial
Aligner up or down.
Note: Each position represents 6 mm
increments.
3. 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 Tibia Alignment Guide later
on.
4. Visually align the Tibial Adjustment Mechanism
in varus/valgus and in tibia slope by aligning
the rod of the Tibial Aligner parallel to the tibial
mechanical axis in both the frontal and sagittal
planes.
Note: The rod of the Tibial Aligner has a built-in
slope of 5°.
Warning: Ensure that the Tibial Adjustment
Mechanism is positioned within the specied
ranges. Not doing so may result in potential
interference between the screws and the
spikes of the Tibial Alignment Guide when the
spikes of the latter instrument are impacted
into the tibia.
