A. Femoral Preparation A.4. Femoral Component Sizing 5 Extract the 3.2 mm Twist Drills 11 and Spikes 8 with a Pin Extractor 13 and remove the Distal Femoral Cutting Guide 10 after resection. Place a Femoral Sizer 14 flush against the resected distal femur, with the two feet rested flat against the posterior femoral condyles and ensure its stylus touching the lowest point of the anterior femoral cortex. The estimated size is indicated on the front and tight the screw of the Femoral Sizer 14 . To estabilish a 3° external rotation, create the fixation pin holes with 3.2 mm Twist Drills 11 through the holes that correspond to the affected knee (left or right) on the front of the Femoral Sizer 14 . The neutral position can simply be created by drilling the fixation pin holes through the drill holes labelled “0” on the front of the Femoral Sizer 14 . NOTE : The U2 Knee primary system is an anterior reference system. If the indicated size on the face of the guide is between two sizes, it is generally preferred to choose the smaller one. The additional bone resection will be removed from the posterior condyles. 13 Pin Extractor 9303-5002 14 Femoral Sizer Anterior Ref 9303-7101-RE 3º External rotation No rotation Left/Right
