Optional Proximal Tibial Cut
(cont.)
Optional Tibial Augment Resection
If a tibial augment is necessary, use the resection
guide (angel wing) to estimate the amount of bone
resection needed to establish a supportive plateau
through the tibial cut guide augment slots.
Use a reciprocating saw to make the vertical augment
resection through the cut guide to the planned depth
(Figure 15). Use an oscillating saw to make a 5 mm
or 10 mm bone resection (Figure 16). Remove the
instruments and finish cuts if needed.
Note:
If two 10 mm or 15 mm tibial augments
are being utilized, they will cover the fins of the
keel reducing rotational resistance. Consider
using a Trabecular Metal Cone to restore rotational
resistance.
Note:
Tibial augment resection can also be
prepared using the tibial augment cut guide
at a later stage in the surgical procedure in the
Optional Tibial Augment Resection section on
page 20.
