ACL

Anterior Cruciate LigamentInjury & Anatomy

A key stabilising ligament inside the knee, commonly injured in sport.

The Anterior Cruciate Ligament is one of the main ligaments inside the knee, resisting forward movement and rotation of the shin bone on the thigh bone. It is frequently torn in cutting and landing sports, often requiring surgical reconstruction and lengthy rehabilitation. Return-to-sport decisions after ACL injury rely on strength, hop-test symmetry and psychological readiness.
