Attached Tibial Plate Inserter
Depress the lever of the tibial inserter to extend the
metal distal tab (Figure 139). Insert the tab into the
implant’s dovetails on the central portion of the tibial
implant. Slide the tibial inserter posteriorly until the tab
engages the dovetails (Figure 140). Release the lever to
secure the tibial inserter to the tibial implant. Ensure the
tibial inserter is seated flush to the proximal surface of
the tibial implant (Figure 141).
Sublux the tibia anteriorly to allow adequate clearance
to insert the tibial implant into the prepared bone. Do
not apply substances other than bone cement to the
tibial implant (i.e. do not dip implant into antibiotics or
other substances). Keep the implant clean and free of
debris prior to cementing. Place a layer of cement on the
underside of the tibial baseplate, around the keel, on the
resected tibial surface, and in the tibial IM canal.
Position the tibial plate onto the tibia and use the tibial
inserter to impact it until fully seated.
To release the inserter from the implant, depress
the lever on the tibial inserter. The handle will move
in a superior direction away from the tibial implant
(Figure 142). Tilt the handle posteriorly to disengage the
distal tab of the inserter from the plate (Figure 143).
Thoroughly remove any excess cement in a consistent
manner. Allow the cement to fully cure before performing
a trial ROM or inserting the bearing.
