The Anterolateral Ligament (ALL): Anatomy, Biomechanics and Function

Steven Claes, MD, PhD, (University of Leuven, Belgium) asks the compelling question, “How can acentrally located cord-like structure like the anterior cruciate ligament (ACL)actually prevent rotation?” Dr. Claes systematically explains the extensivebiomechanical testing that compares the effects of ACL and ALL on internaltibial rotation and the pivot-shift. He goes on to demonstrate the minimallyinvasive ALL reconstruction technique to increase rotational stability.
