Establish Size and Rotation of Tibia
(cont.)
Technique Tip:
Do not impact, lever, or pry the tibial
sizing plate handle; this instrument is designed for
alignment purposes only. Use the alignment rod in
the hole or slot in the tibial sizing plate handle to
verify proper tibial plate varus/valgus alignment.
(See Appendix A for correcting varus/valgus
resections)
Technique Tip:
If using a screw through the anterior
medial hole on the periphery of the cemented tibial
sizing plate, ensure that the cemented tibial sizing
plate remains in the desired position and does not
lift off posteriorly.
Drill and Broach Tibia
The keel of the tibial implant has a unique location for
every size; therefore, it is critical to select the proper
size at this step before drilling and broaching. Once
these subsequent steps have been performed, the size
should not be changed. If desired, femoral finishing
can be performed in conjunction with provisional
trialing at this stage to assure that the desired range
of motion and soft tissue balance can be attained with
the cemented tibial sizing plate in place prior to drilling
and broaching the tibia.
By hand, place and hold the cemented tibial drill
guide on the tibia cemented tibial sizing plate, by first
engaging the posterior tabs in the undercuts in the
cemented tibial sizing plate and then making sure that
the distal anterior portion of the cemented tibial drill
guide is flush against the cemented tibial sizing plate
(Figure 51a).
Use the cemented tibial drill and drill until the center
of the size-specific engraved line on the cemented
tibial drill is in line with the top of the cemented tibial
drill guide (Figure 51b). After drilling is complete,
remove the cemented tibial drill and cemented tibial
drill guide.
Technique Tip:
Insert cemented tibial drill into
cemented tibial drill guide prior to starting
cemented tibial drill. By hand, hold the cemented
tibial drill guide flush against the cemented tibial
sizing plate while drilling.
