Arthroscopic Anterior Cruciate Ligament Femoral Tunnel Visualization for Button Fixation.

Abstract

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) remains one of the most commonly performed procedures in orthopaedic surgery. We describe a technique to visualize the button being advanced through the femoral tunnel using an arthroscope placed in the anteromedial portal. Looking into the femoral tunnel in line with the sutures, this technique allows the surgeon to directly visualize the femoral button as it traverses the femoral tunnel and confirms that it is engaged over the femoral cortex. Certain complications can arise, however, with the use of a suspensory fixation with a button on the femoral cortex. This method can decrease operative time and complication rates.
