ACL footprint and tunnel position. a) A medial view of the femur of knee A following resection of the native ACL. The femoral origins of the anteromedial bundle (red) and the posterolateral bundle (blue) are marked. b) A superior view of the tibia of knee A following resection of the native ACL. The tibial insertions of the anteromedial bundle (red) and the posterolateral bundle (blue) are marked. c) and d) Oval shaped bone tunnels are drilled in both the femur and tibia based on the marked native attachment sites of the ACL. The schematic drawing shows the sizing of the tunnels (knee B isn't shown).
