Fine Tuning Tibial Resection Height
Bring the knee into extension and place the tibial
resection spacer tongue into the slot of the tibial
cutting block and allow the paddles to loosely rest
against the distal cut surface of the femur (Figure 22).
Apply traction to the leg to replicate appropriate
tension on the knee ligaments.
Gently apply pressure to the lever toward the body
of the handle. Adequate extension space will allow
the lever to rest easily on the body of the handle. If
moderate to excessive force is needed to fully depress
the lever, adjust the depth of the tibial cutting block
by using the height adjustment thumb wheel to resect
more tibial bone, and confirm the extension space by
easily depressing the lever to the paddle body.
Repeat previous step at 90 degrees of flexion to ensure
that flexion and extension spaces match.
Fine-tune the tibial resection level by using the height
adjustment thumb wheel (Figure 23).
