3.4.3 Distal Femoral Cut Guidance
1. Install the Femoral Adjustment Mechanism on the
anterior side of the Femoral Reference by aligning
the arrows laser-marked on the instruments.
2. Clip the Cut Guide Pod on the Cut Guide and
insert the two long pegs of the Femoral A/P Slider
into the Femoral Adjustment Mechanism.
3. Slide the Femoral Adjustment Mechanism down
towards the distal condyles to the half way mark.
4. Adjust exion/extension and varus/valgus angles
using the gold screw for exion/extension and
green screw for varus/valgus.
Note: The navigated values will be displayed on
the Cut Guide Pod: the LEDs will be green when
the angle is less than two degrees o from the
target angle, and red when the angle is two
degrees o or more from the target angle. The
navigated values will also be displayed on the
iASSIST V2 Tablet: the numbers will be white
when the angle is one degree in range of the
target, and red when the angle is out of this
range.
Warning: It is suggested to colorblind users
to rely on the numbers on the Pod and Tablet
displays.
Warning: The leg should be elevated to obtain
more than 45° exion (in relation to the
operating table plane) in order for the system
to be able to compute angle values.
5. Once the adjustment is completed, slide the
Femoral Adjustment Mechanism towards the
femur until it is fully seated on the most distal
condyle.
