B. Tibial Preparation B.1. Tibial Intramedullary Alignment Method B.1.1. Pilot Hole There are two options for preparing tibial platforms. One is the intramedullary alignment method, and the other is the extramedullary alignment method. Flex the knee joint to the maximum angle and expose the whole tibial plateau by moving it anteriorly. Use the Starter 1 to create a pilot hole which is located at approximately 10 mm posterior to the origin of anterior cruciate ligament. Then, use an 8 mm Twist Drill 2 to create canal with a depth of approximately 100 mm into the tibial. After taking out the drill, it is recommended to apply an Alignment Rod 3 into the marrow cavity several times to reduce the risk of fat embolism. Connect the T-Handle 5 to the Tibial IM Rod 18 and insert the assembly manually into tibial canal through the narrowest point inside. Then, remove the T-Handle 5 . If it is difficult to insert or align the Tibial IM Rod 18 , enlarge the pilot hole with the 8 mm Twist Drill 2 again. 18 Tibial IM Rod 9401-2203 7
