The femoral/tibial revision cutting block is screwed to the femoral suspension device and
positioned over the trial stem extension (Ø 8 mm). The handles can be attached.
Note
In revision cases, the 7 mm distal revision spacer for femoral condyle is attached to the
femoral suspension device (black plastic component in picture). This substitutes the missing
distal bone substance. The resulting resection remains still 2 mm.
Important
For preventing any confl ict with the trial stem, the most lateral 0 pin hole of the femoral /
tibial revision cutting block is preferred.
The bone pin on the femoral suspension device is removed with a pin extractor. After loosening
the fi xation screw, the trial stem with extension (Ø 8 mm) is removed using the modular
handle.
The suspension device is now removed.
Notes
The resection depth can be adjusted proximally and distally in 2 mm increments (±4 mm).
The side handles can be removed from the femoral suspension device and attached on the
femoral/tibial revision cutting block.

Locating the distal femoral cutting block
The 6° femoral bushing corresponds to the angle
determined in the preoperative planning. The femoral
bushing is inserted into the femoral suspension device,
so that depending on which side is the operation, the
mark L for left knee or R for right knee is visible on the
arrow ▼.
Note
Make sure that the femoral bushing is inserted in the
correct (L or R) position. Adjustment and correction
occurs with removing, rotating by 180° and reinserting
the femoral bushing.
Align the device with regard to rotation. Note that the
removable handles are parallel to the epicondylar axis.
After preliminary drilling with the Ø 3.2 mm drill, from
distal the femoral suspension device is fi xed with a
bone pin (75 mm long).
After preliminary drilling with the Ø 3.2 mm drill, the
femoral/tibial revision cutting block is fi xed with two
bone pins (75 mm long) through the holes marked 0.
This position resects 9 mm from the distal femur, which
corresponds to the distal thickness of the femoral
prosthesis without femoral blocks.
