Set the Final Resection Level
With the tibial cut guide flush against the anteromedial
edge of the tibia, insert the MIS tibial depth resection
stylus into the hole on the top of the tibial cut guide.
For a minimal cut, swing the 2 mm arm of the stylus
over the defective tibial condyle. Adjust the tibial cut
guide up or down by rotating the thumb wheel until
the tip of the 2 mm stylus rests on the surface of the
condyle (Figure 1j). This will position the tibial cut
guide to remove 2 mm of bone below the tip of the
stylus.
Alternatively, swing the 10 mm arm of the MIS tibial
depth resection stylus over the least involved tibial
condyle. Adjust the tibial cut guide until the tip of the
10 mm arm rests on the surface of the condyle (Figure
1k). This will position the tibial cut guide to remove 10
mm of bone below the tip of the stylus.
