Important
To ensure optimal positioning of the femoral
drill guide on the condyles, gently tap the
M/L area – not the drill guide section of the
instrument.
Open the femoral IM canal as far as the stop,
using the ∅ 8/14 mm IM stepped drill. The
drill direction is along the femoral axis.
Important
The femoral IM canal, which determines the
position of the implant stem, must be opened
carefully (reference for the femoral position)
so as to prevent development of a relative
extension position (risk of notching) or flexion
position (projecting patella).
Using the modular handle, carefully insert
the ∅ 8 mm IM rod approximately up to the
isthmus of the femoral IM canal and then
remove.
It is important to work carefully, to prevent
excessive pressure in the IM canal.
Preparing the femoral anchorage
Open the femoral IM canal with the long
∅ 14 mm reamer until the mark on the
reamer reaches the intercondylar notch, or
the bone resection if performing a revision.
The reamer should be aligned parallel to the
femoral anatomical axis, both anteriorly and
laterally. Now remove the modular handle.
If an intramedullary obstacle is encountered
(e.g., a hip implant), the short reamer may be
used as an alternative.
