The anterolateral ligament (ALL) is a ligament on the lateral aspect of the human knee, anterior to the fibular collateral ligament.[1]
Perhaps the earliest account of the ALL was written by French surgeon Paul Segond in 1879, in which he described a ligamentous structure between the lateral femur and tibia.[2][3]
Claes and Bellemans (2013) found that the ALL originates at the lateral epicondyle of the femur, and inserts at the anterolateral aspect of the proximal tibia.[1] However, Vincent et al. (2012) reported the origin to be the lateral femoral condyle.[4]
Clinical relevance
The ALL, which is presumed to occur in at least 97% of the human population,[1][4] seems to stabilize medial rotation of the knee.[1]
The "pivot shift" phenomenon in anterior cruciate ligament injury patients may be ascribed to additional trauma to the ALL.[1] The anterior cruciate ligament (ACL) is a major ligament of the human knee.
The Segond fracture is probably an avulsion of the anterolateral ligament. In such injuries, fragments of the lateral tibial condyle of the knee are torn from the bone by soft tissue.
