Finish the Patella
For the NexGen Primary Porous Patella
With Trabecular Metal Material
Center the appropriate patellar drill guide over the
resected patella surface with the handle on the medial
side of the patella and perpendicular to the tendon.
Press the drill guide firmly in place so that the teeth
fully engage and the drill guide sits flat on the bone
surface (Figure 12q). Drill the peg hole making sure
the drill-stop collar contacts the top of the drill guide
(Figure 12r).
Note:
The primary porous patellar clamp may be
used to fully seat the drill guide on hard sclerotic
bone surfaces.
For the NexGen All-Polyethylene Patella
Center the appropriate patellar drill guide over the
patella with the handle on the medial side of the patella
and perpendicular to the tendon. Holding the drill
guide firmly in place, drill the three peg holes using
the patellar/femoral drill bit (Figure 12s).
