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. Also, the Segond fracture is probably a bony avulsion of the anterolateral ligament.
