Posterior slope is adjusted by depressing the button
on the side of the EM tibial guide base and moving the
base forwards or backwards to allow the tibial cutting
block (with 7 degrees of slope) to increase or decrease
posterior slope.
EM tibial guide shift being parallel to the long axis of
the tibia gives seven degrees of posterior slope.
Adjust the initial guide height accordingly by placing the
universal tibial cutting block against the proximal tibia
at the estimated resection level (Figure 19).

Resection
Attach the tibial universal cutting block (which has a 7
degrees posterior slope built-in) to the EM tibial guide.
Position the EM tibial guide on the tibia and place the
spring-loaded arms of the ankle clamp around the distal
tibia just above the malleoli (Figure 18).
