All other provisional components can be removed by
inserting and locking the non-threaded end of the
slap hammer into place of the femoral and/or tibial
provisional (Figures 92, 92a and 92b).

TASP Removal
The entire TASP construct must be removed to
exchange the bottom in the TASP construct. To remove
or exchange the bottom, disengage the provisional
lockdown screw by rotating the 3.5 mm hex driver in
a counterclockwise direction. Remove the provisional
lockdown screw from the joint. Flex the knee greater
than 30 degrees, push in the TASP posteriorly to
disengage anteriorly (1) and lift (2) the tibial sizing
plate handle while attached to the TASP construct
(Figure 91).
Note:
Varus/valgus forces may make it difficult to
remove the TASP construct. To aid in the removal
of the TASP and prevent breakage, ensure that the
joint is in a neutral position when removing the
TASP construct.
Note: Use only the tibial sizing plate handle to
remove the TASP construct. The use of other
instruments may damage or break the TASP.
Note: Do not implant the TASP components.
