The anterior cruciate ligament is one of the major stabilising ligaments in the knee. It is a strong, rope-like structure located in the centre of the knee running from the femur to the tibia.
The anterior cruciate ligament prevents the tibia moving forward and rotating abnormally on the tibia. When it ruptures it does not heal itself and the knee often becomes unstable or gives way. Often associated with the cruciate ligament rupture there can be damage to other structures in the knee such as bone, cartilage or menisci and these injuries may also need to be addressed at the time of surgery.
