The femoral component is hammered using
the impactor. Here, too, continuous pressure
must be maintained and excess cement
removed.
Important
Make sure that the posterior femoral condyles
do not come into contact with the tibial com-
ponent when impacting the femoral component.
We recommend covering the tibial component
with a compress.
Before the femoral component cement has set,
the plastic lug that protects the box against the
entry of cement must be removed.
Last controlling
Prior to defi nitive assembly of the tibial insert
it is possible to use the tibial insert trial for a
fi nal trial reduction.
Before the cement has set, the excess cement
must be removed in extension.
Insertion of the tibial insert
The tibial insert of the corresponding size
(see page 55) may only be inserted when the
cement has fully hardened.
In 90° fl exed position, the tibial insert is placed
on the femoral component rotation peg and
slid into the tibial component by hand.
Important
Note the correct anatomical alignment. It is
important to make sure that no soft tissue
is coming between the tibial insert and the
tibial component.
Note
In order to prevent the anterior metal clamp
from falling out, handle the tibial insert care-
fully.
