Anterolateral ligament of the knee

   
  • Anterolateral ligament (ALL) originates on the lateral femoral epicondyle and inserts on the anterolateral tibia.
  • Segond fracture is actually a bony avulsion of the ALL. (Claes S, Arthroscopy. 2014 Nov;30(11):1475-82)
  • Segond fracture (lateral capsular sign):  a lateral capsular avulsion fracture occurring just distal to the lateral tibial plateau which is associated with ACL tear.
