Trial Cutting Guide Orientation (continued)
Scorpio Trial Cutting Guide
Rotation
With the knee flexed at 90°, appropriate
external rotation can be set by
positioning the TCG on the tibial trial
insert so that it is seated with no
varus/valgus tilt. The transepicondylar
axis or Whiteside’s axis can be used to
estimate rotation as well.
A second headless fixation pin should
then be placed in the TCG’s anterior pin
hole to fix the TCG position once
rotation has been established (Figure 17).
Place as many pins as necessary to
securely fix the TCG on the distal femur.
Note: Headless pins may now be
replaced with short headed fixation
pins to facilitate joint reduction.
Note: The TCG trial inserts do not
have a post. This allows for a more
accurate assessment of the
ligaments during trialing.
