Locating the tibial cutting block
The two tibial resection guide IM components
are coupled together by jointing arrow Ø to
arrow × and pressing the button.
The femoral/tibial revision cutting block is
attached to the tibial resection guide IM with
the top small grub screw and slid completely
onto the trial stem extension (
Ø 8 mm).
Note
Ensure the lock lever is set to OPEN to slide in
place the tibial resection guide IM. The lock
lever is then reversed to fix the tibial re section
guide IM in place.
The femoral/tibial revision cutting block is
fi rst lifted upwards by pressing the button so
the tibial stylus can be attached.
Setting the resection height
The tibial stylus is positioned on the tibial
plateau. The tibial stylus can be used for both
primary resections (11 mm marking) and for
revision resections (1 mm marking).
Notes
In primary revision procedures, the 11 mm
tibial stylus is positioned on the lowest point
of the less-damaged condyle.
In revision procedures where no tibial aug-
mentation blocks are required the 1 mm
tibial stylus is positioned on the lowest area
of the tibial plateau.
In revision procedures where augmentation
blocks are required, 1 mm tibial stylus is
positioned on the lowest point of the less-
damaged condyle.
