Symmetric (All-Poly) or Asymmetric Patella
(All-Poly and Metal-Backed)
> Assemble the Patella Cement Cap and the Patella
Clamp Base to the Patella Clamp
(See Assembly 9) .
Note: If necessary, use a curette to mark the locations of
the fixation peg holes.
> Place the Patella Component onto the prepared
patella, making certain the fixation peg holes are
aligned to the corresponding holes.
> Seat the Patella Component onto the prepared patella
by clamping the Patella Cement Cap, Patella Clamp
Base and Patella Clamp assembly.
Note: Insure that the silicon o-ring of the Patella
Cement Cap is placed on the articulating surface of the
Patella Component.
Note: Leave the assembly clamped to the patella
while excess cement is cleared and polymerization
is complete.
> Disengage the Patella Clamp by pressing the
gold release trigger.
> To further seat the baseplate, attach the Tibial
Baseplate Impactor to the Impaction Handle.
> Place the Tibial Baseplate Impactor on to the
Primary Tibial Baseplate straddling the central island.
Ensure the Tibial Baseplate Impactor sits flat on the
top surface of the Primary Tibial Baseplate.
> Impact until the Primary Tibial Baseplate is fully
seated.
Note: Clear all excess bone cement while maintaining
position of the Primary Tibial Baseplate.
PS or CR Tibial Insert
> Prior to assembly of the PS or CR Tibial Insert, the
PS or CR Tibial Trial Insert may be placed on the
Primary Tibial Baseplate to once more assess joint
stability and range of motion.
> To assemble the PS or CR Tibial Insert, distract the
joint and angle the insert posteriorly into the Primary
Tibial Baseplate. The posterior lip of the Tibial Insert
must fit beneath the lip on the posterior Primary
Tibial Baseplate wall.
> Attach the Tibial Insert Impactor to the Impaction
Handle and impact to snap the Insert in place
anteriorly. The PS or CR Tibial Insert is fully seated
once the locking wire locks under the barbs on the
anterior/interior surface of the Primary Tibial
Baseplate wall.
