Ligament Robot.gifI think it’s safe to say that the anterior cruciate ligament (ACL) is the most-studied anatomic structure in the musculoskeletal system.  Yet more than a century ago, French surgeon Paul Segond identified a lesser structure in the knee, the anterolateral ligament (ALL), presuming it to be an important stabilizer of that joint. More recent research has associated this ligament with the anterolateral joint line capsular avulsion fragments associated with some ACL ruptures.

A “fashionable” interest in the ALL has re-emerged in that cyclic way orthopaedic surgical techniques and indications are prone to. Some surgeons are designing reconstruction procedures in which the ALL is addressed in addition to the ACL.
