Varus/Valgus Alignment
>
Medial/Lateral offset can be adjusted by pushing the
bronze button (1) and sliding the assembly medially
until the shaft intersects the center of the tibia .
>
Once triaxial alignment is achieved, release the
bronze button .
Tibial Slope Adjustment
>
If the Proximal Rod is parallel to the tibia, the slope
is 0° or 3° depending on which Tibial Adjustment
Housing is used .
>
Tibial slope can be adjusted by pressing the bronze
button (2) .

Tibial Resection Assembly
>
The Tibial Resection Guide, available in left and right
configurations, and the Universal Resection Guide
are designed to avoid soft tissue impingement .
>
The tibial resection assembly has five parts: the
appropriate Tibial Resection Guide, the Ankle
Clamp, the Distal Assembly, the Tibial Alignment
Proximal Rod and the Tibial Adjustment Housing .
These are assembled first .
Note: The Tibial Adjustment Housing is available in 3º
slope and 0º slope (optional) .
Tibial Slope
>
Place the ankle clamp around the ankle and unlock
the locking switch .
>
Tibial slope can be checked by verifying that the long
axis of the assembly is parallel to the tibia .
Caution:
• The center of the ankle is generally in line with the
second metatarsal, unless ankle and foot deformity
is present . The assembly should be aligned over the
center of the ankle .
• Because of the shape of the tibia, the distal portion of
the guide will be further away from the tibia than the
proximal . Failure to recognize this will result in plac-
ing the component in extension .
