Surgical Technique
Option One: Anterior Referencing Technique (cont.)
When the proper rotation and the mediolateral and
anteroposterior position are achieved, secure the
finishing guide to the distal femur. Use the screw
inserter/extractor to insert a 3.2 mm headed screw
or predrill and insert a hex-head holding pin through
the superior pinhole on the beveled medial side of the
femoral finishing guide (Figure 6b). Then secure the
lateral side in the same manner.
For additional fixation, drill the post holes using the
patellar/femoral drill bit (Figure 6c). Then insert 6.5
mm x 35 mm periarticular bone screws through the
post holes.
If desired, predrill and insert two short-head holding
pins through the inferior holes on one or both sides of
the guide.
Use the resection guide through the anterior cutting
slot of the finishing guide, and check the medial and
lateral sides to be sure the cut will not notch the
anterior femoral cortex (Figure 6d).
Alternatively, the MIS locking boom attachment can
be attached to the face of the femoral finishing guide.
Use the MIS locking boom or telescoping locking
boom to check the location of the anterior cut and
determine if notching will occur (Figure 6e). The boom
tip indicates where the anterior femoral cut will exit
the bone.
