9 Assemble the Tibial Cutting Jig 21 to the selected Tibial EM Alignment Guide 22 . With the knee fully flexed, position the distal portion of the Tibial EM Alignment Guide 22 at the anterior ankle joint with the supramalleolar spring tabs. Position the proximal portion of the Tibial EM Alignment Guide 22 by impacting the spikes of the Tibial EM Alignment Guide 22 into the central portion of the proximal tibial plateau. The cutting amount may be determined by inserting the Tibial Stylus 20 in the resection slot. NOTE : The Tibial Stylus 20 allows two options for to position the Cutting Guide; 2 mm or 9 mm cutting levels. When the Tibial Stylus 20 tip marked 2 mm is positioned on the low point of the tibial plateau, the bone resection will occur 2 mm below the contact point of the stylus tip. If the 9 mm stylus tip is positioned on the high point of the tibial plateau, it will position the Tibial Cutting Jig 21 9 mm below the contact point of the stylus tip. Once the elevation is chosen, the 3.2 mm Twist Drills 11 are placed in the “0” hole option of the Tibial Cutting Jig 21 . Additional peripheral Drills 11 or Spike 8 may also be used to secure the Tibial Cutting Jig 21 . Once the Tibial Cutting Jig 21 is securely positioned, the Tibial EM Alignment Guide 22 may now be removed by utilizing the Spike and Tibial EM Guide Extractor 23 . Resection of the tibial plateau is now performed by using a 1.27 mm saw blade. NOTE : Prior to resection, if the surgeon wishes to increase or decrease the tibial resection thickness, the “+2” or “-2” hole locations may be utilized to re-position the Tibial Cutting Jig 21 . B.
