Component Implantation
Baseplate Impaction
Caution: Pegs on the Triathlon Tritanium Tibial
Baseplate are sharp . Take care when handling the
baseplate .
Tip: At this stage, cysts or voids on the surface of the
tibia may be bone grafted with local resected cancellous
bone .
>
Introduce the Triathlon Tritanium Baseplate onto the
prepared tibia taking care to align keel slot and peg
holes with the keel and pegs of the baseplate .
>
Impact until fully seated . Ensure baseplate is fully
seated prior to proceeding .
>
Unlock the locking lever on the Baseplate Impactor
Extractor and remove the assembly from the
baseplate . Discard the Impactor Pad .
Caution: It is recommended that the Impacter Pad be
left on during impaction . Discard the Impactor Pad
following impaction of the baseplate and prior to the
Tibial Insert Implantation step . Do not implant the
Impactor Pad .
Note: Do not rock the baseplate in the bone because it
could affect the press-fit .
If Cementing:
>
If a decision is made to cement the Triathlon
Tritanium Baseplate, the keel must be re-prepared
with the Cemented Keel Punch .
>
The appropriate Tibial Template and Keel Punch
Tower must be pinned back into place . The
Cemented Keel Punch is then impacted into place to
open up the keel slot to allow for a cement mantle .
>
If necessary, before applying the bone cement,
remove bone debris and tissue from the Triathlon
Tritanium Baseplate .
