Learn more about anterior cruciate ligament injuries

What is the anterior cruciate ligament?


The anterior cruciate ligament is 1 of 4 key ligaments in the knee. Ligaments connect bones together so the anterior cruciate ligament connects the thigh bone (femur) to the shin bone (tibia). It crosses in the centre of the knee joint (shown in orange in the image to the right) and is the most commonly injured knee ligament.
