Step Nine: Prepare the Tibia
(cont.)
Attach the MIS sizing plate handle to the broach and
trialing plate assembly (Figure 9e). The handle should
be inserted on the medial side of the broach plate to
provide clearance for the patella. Extend the lever on
the handle and engage the tabs on the handle with the
grooves on the broach plate by positioning the lever
lateral to the dovetail, and clamp the lever to secure.
Ensure that the broach and trialing plate assembly is
positioned as far posteriorly as possible on the lateral
side without overhanging the tibia. This position may
leave some bone exposed on the posteromedial tibia
when the plate lines up with the posterolateral cortex.
Insert a small head holding pin into the lateral pin hole
on the top face of the broach plate (Figure 9f).
Only the small head holding pins may be used through
the top face of the broach plate. This pin will allow the
articular surface provisional to rotate on the assembled
broach and trialing plate.
It is recommended to use one hole on the top broach
plate face and one anterior oblique hole on the
opposite side if additional plate stability is needed.
