Instruments AiO Block Threaded Pin 30 mm/50 mm Screwdriver Once the size is determined, rotate the upper knob with the Screwdriver to the lock position to secure the chosen size and lock the cutting block. Fix the anterior and posterior slots with Threaded Pins and proceed with the anterior and posterior resection. AiO Block Screwdriver Instruments Fine Tune Occasionally, even when the proper size is chosen the desired resection level may be unsatisfactory. If this occurs, a slightly redistributed anterior and posterior bone resection may be considered. With the upper knob in the locked position, use the Screwdriver to rotate the bottom knob clockwise to allow for less anterior, and more posterior cut; conversely, rotate the bottom knob counterclockwise to make more anterior and a smaller posterior cut. The range of adjustment is between +2 mm and -2 mm to the standard 9 mm posterior cut. Clockwise Rotation: Less Anterior, More Posterior Resection Counterclockwise Rotation: More Anterior, Less Posterior Resection 21 22
