6. While continuing to firmly grip the distal clamps
around the malleoli, impact the instrument until
both spikes are fully inserted in the tibia.
Warning: Impact the tibial alignment guide in-
line with the spikes of the instrument. Off-axis
impaction may result in bending of the spikes.
The two spikes of the tibial alignment guide
must be positioned and inserted carefully in
order to avoid loosening.

7. Ensure the distal clamps of the tibial alignment
guide remain securely positioned on the malleoli.
If a readjustment is necessary, ensure the shaft
of the guide remains immobile and in proper
alignment. Adjust by rotating the distal part of
the guide and resecure the clamps around the
malleoli.
8. Lock the blue knob on the distal tibial alignment
guide.
9. Attach the tibial positioner and the tibial adjustment
mechanism assembly onto the proximal part of the
tibial alignment guide.
Warning: Do not pull on the distal part of the
tibial alignment guide once both spikes have
been inserted into the tibia. Doing so may
result in bending of the spikes.
