Femoral tunnel placement. (A) Arthroscopic view of the medial wall of a lateral femoral condyle of a left knee from a lateral standard portal. The midpoint of the femoral origin of the ACL is marked with a microfracturing instrument. Thereafter, the position can be checked through a medial portal view (B). If the position looks adequate, the 2.4-mm guidewire marked for length measurement is inserted and drilled through until the mark is close to the lateral notch wall (D, arthroscopic view from the medial portal; E, schematic view). Finally, a small incision is made in the skin at the exit point of the guidewire for insertion of the indirect measuring instrument (C, intraoperative view of a left knee from lateral). (ACL, anterior cruciate ligament.)
