22 | iASSIST 2-Pod Version Surgical Technique
3.5 Tibia Procedure
Warning: At patient draping, take care to leave
the malleoli accessible to the surgeon.
The iASSIST Knee system is compatible with Femur rst
and Tibia rst procedure. See the “Femur Procedure”
section to start with the femur.
Note: There are three dierent techniques
for tibia resection. The rst one is the
Freehand Positioning of the Tibial Adjustment
Mechanism and will be described here. Two
more techniques will be described in section
“Alternative Techniques to Prepare For Tibia
Cut”.
3.5.1 Workow Selection for Tibia
1. To Start a Tibia first procedure:
For a left knee procedure, clip the “Reference”
Pod to the back receptacle of the Tibial Left
Adjustment Mechanism.
Figure 3.5.1
Tibia Workow Selection
For a right knee procedure, clip the “Reference”
Pod to the back receptable of the Tibial Right
Adjustment Mechanism.
2. 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.
3. Visually align the elevator rod of the Tibial Cut
Guide with the tibial mechanical axis in both the
frontal and lateral planes aiming to achieve a
neutral orientation.
