An ACL tear does not automatically mean you need surgery. Many people can function well following appropriate rehabilitation, particularly if their knee remains stable and their activities do not involve significant pivoting or sudden changes of direction.

The most important question is not simply whether your ACL is torn, but whether your knee will remain stable for the activities you want to return to, and whether other structures in the knee have also been injured.

When can ACL injuries be treated without surgery?

Non-operative treatment may be appropriate if:

• your knee does not give way during everyday or sporting activities

• you are comfortable modifying your activity if necessary

• you mainly participate in straight-line activities such as running, cycling or swimming

• there are no associated injuries to meniscus or ligaments requiring surgery

A structured rehabilitation programme with an experienced physiotherapist is an important part of this approach.

When might ACL surgery be recommended?

ACL repair or reconstruction may be considered when:

• you want to return to pivoting or contact sports such as rugby, football, netball or basketball

• your occupation or lifestyle involves frequent pivoting, jumping or landing

• your knee continues to give way despite good rehabilitation

• you have a repairable meniscus injury or another ligament injury requiring surgery

• recurrent instability places other structures within your knee at risk

Repeated episodes of the knee giving way can cause permanent injury to the meniscus and cartilage. The purpose of ACL surgery is therefore not simply to treat the torn ligament, but to restore stability, protect the knee from further injury and help you return safely to the activities that matter to you.
