Optionally, theEM alignment guide can be removed by lifting thelever on the EM proximal tube up to the open position,translating the EM alignment guide anteriorly whileleaving the cut guide in place (Figure 29). If the EMalignment guide has been removed, additional 2 mmadjustments may be made by shifting the cut guide tothe sets of holes marked “+2”, and “+4”. The markingson the cut guide indicate, in millimeters, the amount ofadditional bone resection relative to the standard tibialresection set by the cut guide and stylus. If a pin orscrew was inserted into the 12 mm vertical slot, it willneed to be removed to make the 2 mm adjustments.Once the resection level has been determined, insert a3.2 mm trocar tipped pin in the oblique hole indicatedby a lock pin symbol, to further secure the cut guide(Figures 30a and 30b). If a pin or screw was insertedinto the 12 mm vertical slot, then a pin through theoblique hole may not be needed for secure fixation.Optional TechniqueIf desired, the resection can be made from the topsurface of the cut guide. The top surface of the cutguide is 4 mm above the cut slot (Figure 31); therefore,the position of the cut guide must be adjusted bymoving the cut guide from the headless pins andreinserting the cut guide through the holes marked"+4" (Figure 32).1.
