What is an ACL reconstruction?1
An ACL reconstruction is a surgery which replaces a torn ACL – or anterior cruciate ligament – with new ACL graft tissue — either taken from the patient's own body (tissue from the main patellar tendon or the hamstring) or donated from someone else (called an allograft).
The ACL is important in stabilising your knee during movement. When torn, your knee can collapse when making twisting or turning movements. Torn ACLs are often caused by contact sport or skiing injuries.
An ACL reconstruction is usually performed by an orthopaedic surgeon.
