After preliminary drilling with the ∅ 3.2 mm
drill, set the femoral/tibial cutting block in
place by inserting two bone pins (75 mm
long) through the holes marked “0”. This
position resects 9 mm from the distal femur –
a distance corresponding to the distal thick-
ness of the femoral prosthesis.
Important
To prevent any conflict with the reamer, the
most lateral 0 pinhole of the femoral/tibial
cutting block should be favoured.
Remove the bone pin on the femoral suspension device, using the pin extractor. After
loosening the fixation screw, remove the reamer (∅ 14 mm) using the modular handle.
Now remove the suspension device.
Important
The resection depth can be adjusted proximally and distally in 2 mm increments (± 4 mm).
If the resection stylus is used, the distal femoral resection can be checked.
Distal femoral resection
Slide the femoral/tibial cutting block onto the
bone. Perform the distal femoral resection
using a 1 mm (or 1.27 mm option) saw blade
through the 0 saw slot (closed slot with
facet).
Important
To lock the femoral/tibial cutting block, an
additional pin can be inserted into the ob-
lique holes marked “AUX”. Remove the pin
after resection.
If an extension deficit is present, moving the distal resection 2–4 mm proximally to adjust
the extension gap is recommended. For hypermobile patients, a 2 mm smaller distal femoral
resection is recommended.
The distal resection serves as a reference for the following steps, and has to be checked for
accuracy.
Important
The femoral/tibial cutting block should not be removed yet, since it will be used
later.
