Setting the tibial rotation
The tibial rotation is determined anatomically
statically (orientation to the tibial tuberosity,
and the axial alignment rod tip must point to
the center of the ankle joint).
After preliminary drilling with the Ø 3.2 mm
drill, the tibial sizer is fi xed with at least two
bone pins with head.
Remove the chisel guide and the trial stem
and refi t the chisel guide.
Note
Positioning of the chisel guide is achieved by
introducing and rotating the chisel guide
clockwise in the tibial sizer. If insertion or re-
moval proves difficult, a long pin can be used
as a lever, which is placed in the anterior hole
of the chisel guide.
