Optional Technique
To check the location of the anterior
cut and determine if notching will
occur, securely tighten the Locking
Boom Attachment to the face of the
finishing guide. Make certain that the
attachment sits flush with the Femoral
Finishing Guide (Fig. 4e). Connect the
MIS Locking Boom to the attachment
(Fig. 4f). The boom indicates the depth
at which the anterior femoral cut will
exit the femur.

Use the 1.27mm (0.050-in.) narrow,
reciprocating saw blade to cut the
base of the trochlear recess (Fig. 4i)
and score the edges (Fig. 4j). Remove
the finishing guide to complete the
trochlear recess cuts. Use a 1.27mm (0.050-in.) narrow,
oscillating saw blade to cut the femoral
profile in the following sequence for
optimal stability of the finishing guide
(Fig. 4g):
1 Anterior condyles
2 Posterior condyles
3 Posterior chamfer
4 Anterior chamfers
Use the Patellar/Femoral Drill Bit to drill
the post holes (Fig. 4h).
