Tibia Registration
1. Loosen the blue knob on the distal part of the tibial
alignment guide.
2. Position the rod of the tibial alignment guide to
an initial starting orientation per the preset
position (L or R) on the distal part of the tibial
alignment guide.
For a left knee procedure, the preset position is L.
For a right knee procedure, the preset position is R.
3. Place the distal part of the tibial alignment guide
on the ankle by firmly gripping the distal clamps
around the malleoli until both spikes are fully
inserted into the tibia.
Note: The tibial alignment guide is designed
to be self-centered when placed around the
malleoli.
Warning: After wrapping/preparing the ankle,
the surgeon should still be able to palpate the
malleoli.

4. While continuing to firmly grip the distal clamps
around the malleoli, partially insert (2-3 mm) the
longer spike of the proximal part of the tibial
alignment guide through the mechanical axis
entry point, without engaging the shorter spike.
5. While continuing to firmly grip the distal clamps
around the malleoli, set rotation using the tibial
alignment guide. Orient the instrument shaft to
align with the medial third of the tubercle.
