5.5 SETTING THE TIBIAL RESECTION LEVEL WITH
THE EXTRAMEDULLARY GUIDE
Fix the tibial stylus into the dedicated hole on the cutting
guide. One side of the stylus allows to make a 8 mm cut
from the less worn tibia plateau, and the other side to make
a 2 mm from the most worn plateau.
Set the proximal-distal translation of the tibial component
by adjusting the level of the saw slot until the 8 mm side of
the tibial stylus contacts the center of the less worn tibial
condyle.

The goal is to perform a conservative resection that allows
for any corrections or recuts that might be necessary to
re-establish soft tissue balance.
5.6 STABILIZATION OF THE TIBIAL CUTTING
BLOCK
Check the cut height and posterior slope using the angel
wing before fixing the tibial cutting block.
Pin the block to the tibia by using the two parallel positioning
holes marked with a line and one oblique fixation hole.
