Resect the Patella
(cont.)
Apply the patella osteotomy guide medially and
laterally with the jaws at the osteochondral juncture
with the handles of the jig oriented toward the foot.
Apply the guide with the jaws parallel to the dorsal
surface of the patella, while positioning the patella
osteotomy guide stylus over the most prominent
point on the patella. Make the resection with a 1.27
mm (0.050 inch) thick saw blade (Figure 62). Cut the
patella flat so that a smooth surface remains.
Technique Tip:
To facilitate unlocking the patella
osteotomy guide from the patella, apply slight
gripping pressure on the handles of the patella
osteotomy guide and depress the release lever to
unlock the patella osteotomy guide (Figure 63).

Finish the Patella
Using the NexGen
®
Patella Sizing Template, select
the maximum-sized patella that does not overhang,
centered over the 3.2 mm drill hole as a reference for
proper medialization (Figure 64).
Technique Tip:
Do not drill through the center hole
of the NexGen Patella Sizing Template.
Technique Tip:
Eccentric placement of the patella
3–4 mm medially allows for better patella tracking.
