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 6p). The boom
tip indicates where the anterior femoral cut will exit
the bone.
Use a 1.27 mm (0.050 in.) narrow, oscillating saw blade
to cut the femoral profile in the following sequence for
optimal stability of the finishing guide (Figure 6q):

Use the patellar/femoral drill bit to drill the post holes
if not done previously.
Use the 1.27 mm (0.050 in.) narrow, reciprocating
saw blade to cut the base of the trochlear recess
(Figure 6r) and score the edges (Figure 6s). Remove
the finishing guide to complete the trochlear recess
cuts and complete any remaining bone cuts.
