Patellar Component – NexGen Primary Porous
Patella with Trabecular Metal Material
Knee in 70°-90° flexion
Note:
If the implant post begins to engage at
an angle, the implant should be removed and
repositioned perpendicular to the resected surface.
Insert the patella again and reclamp, applying
an even distribution of pressure on the patellar
surface.

NexGen All-polyethylene Patella
Knee in 70°-90° flexion.
Apply cement to the anterior
surface and pegs of the patellar component while in a
doughy consistency. Locate the drilled peg holes and
use the patellar clamp to insert and secure the patella
in place. Fully open the jaws of the clamp and align
the teeth to the anterior surface of the patella and the
plastic ring to the posterior surface of the implant. Use
the clamp to apply a significant amount of pressure
to the implant to fully seat the implant on the patellar
surface. Then remove excess cement.
