•
Most Posterior Lateral Point
This point is used in conjunction with the anterior
notch point and the most posterior medial point for
initial sizing of the implant component.
•
Anterior Notch Point
This point is used as a reference during
prosthesis planning to prevent notching
of the implant component.

Femoral Condyle Surface Mapping
The Femur Free Collection stage (Figure 25) offers
a visualization of the femoral mechanical and
rotational axis previously collected (blue lines) as
well as the four discrete femur landmark points
collected above (yellow dots).
On top of this visualization, the user should
digitize the femoral condyle by moving the point
probe over the entire surface while holding
down the footpedal. The user must input enough
information into the system to appropriately
localize the implant during planning.
Hyperflex the leg to map the posterior portion.
Manipulate the touchscreen to view the surface-
map input in 3D.
