Optional Technique:
Position Based on Trial Range of Motion
Insert the proper size femoral provisional, assembled
broach and trialing plates, and articular surface
provisional. Insert a small-head holding pin through
the anterior hole on the rail of the trialing plate. This
will hold the articular surface provisional in a fixed
central position on the trialing plate.
Flex and extend the knee with the provisionals in
place. With proper soft tissue balancing complete, the
tibial component tends to seat itself in the position
where it best articulates with the femur.
After this process has occurred, mark the position of
the component with methylene blue, electrocautery,
or by placing a pin or MIS screw in the sizing plate
anteriorly. Pin the broach plate in place with small
head holding pins. It is recommended to use one
anterior pin hole and one hole on the opposite side
of the broach plate on the plate face to assure plate
stability. Ensure that the broach plate remains in the
proper position when pinning.
Proceed to Step Eleven.
Note:
Ensure that the trialing plate peg does not
catch on the broach plate during removal.
