Fig 7.

Left knee, with patient lying supine. The tibial anterior cruciate ligament aiming guide and guide sleeve (arrows) (Arthrex) are viewed from outside the knee. The knee is flexed to 60°, and the guide is passed through the medial portal and positioned arthroscopically at the anatomic insertion of the posterior root of the lateral meniscus. The 6.0-mm-diameter FlipCutter is drilled as a 3.5-mm guide pin through the guide sleeve across the tibia to the point of the aimer in the joint through the small medial tibia incision, which also will be used for creation of the anterior cruciate ligament tibial socket.
