Patella Implantation
(continued)
>
Turn the T-handle of the Patella Inserter until the metal backing portion of the
patella implant is fully seated onto the resected surface of the native patella .
Note: The metal backing portion of the patella implant protrudes slightly from
the peripheral polyethylene surface . There may be a slight gap between the
peripheral polyethylene and the bone surface when the central metal backing
portion is fully seated .
Caution: While carefully turning the T-handle, observe through the
windows on the Patella Capture that the patella implant is properly seating
onto the native patella . Stop once the metal backing portion of the implant
is fully seated . Care should be taken to avoid over-compressing the implant
and native patella .
>
Unscrew the T-handle and remove the Patella Inserter and Capture .
>
Re-examine to ensure the the implant is properly seated on the native patella .
If cementing the patella component:
>
If a decision is made to cement the Tritanium Metal-Backed Patella or to
use an All-Poly Patella, the peg holes must be prepared with the All-Poly
Patella Drill (6541-3-524) .
>
If necessary, remove bone and tissue debris from the Tritanium Metal-
Backed Patella .
>
Prepare the bone surface for cementing and apply the cement .
>
To facilitate removal of excess bone cement, do not use the Patella Capture
with the Patella Inserter .
>
Alternatively, the Triathlon Patella Clamp and Express Cement Cap can be
used for cement application insertion .
>
Maintain clamping pressure while excess cement is cleared and
polymerization is complete .
