(A) Diagnostic arthroscopy of the right knee is performed initially, with probing of the ACL to confirm intact fibers of the AM bundle. (B) While viewing through the transpatellar portal, the femoral footprint of the PL bundle is located and outlined with a radiofrequency device. (C) A 6.5-mm femoral tunnel is drilled, preserving the intact AM bundle fibers. (ACL, anterior cruciate ligament; AM, anteromedial; PL, posterolateral.)

Preparation of the tibial tunnel viewing from the lateral portal of a right knee. (A) Through the AM portal, an ACL guide is placed at the center of the PL bundle footprint on the tibia for placement of the guidewire. (B) A curette is placed over the guidewire to protect the intact fibers during tibial tunnel drilling. (C) The PL tibial tunnel is rongeured and prepared for graft passage. (ACL, anterior cruciate ligament; AM, anteromedial; PL, posterolateral.)

View from the lateral portal of the right knee. (A) The graft and EndoButton are passed through the tibial tunnel. (B) Final confirmation of graft position and stability is performed, looking for any signs of pullout, impingement, or inadequate tensioning.
