ACL injuries are common in football, netball, basketball, skiing and martial arts. Many people hear a pop, feel the knee give way and notice rapid swelling.
About ACL injury
The ACL stops the shin bone sliding forward and helps control rotation of the knee. When it tears, the knee can feel unstable, especially when turning or pivoting.
Common causes
- Twisting on a planted foot
- Landing awkwardly from a jump
- Sudden stopping or changing direction
- Contact injuries to the knee
Signs and symptoms
- A pop at the time of injury
- Rapid swelling within hours
- The knee giving way
- Loss of full straightening or bending
How physiotherapy helps
- Early care: calming swelling and restoring full straightening
- Pre-surgery rehabilitation (“prehab”) to improve outcomes
- Post-operative rehabilitation following your surgeon’s protocol
- Progressive strength, balance, running, jumping and agility work
- Return-to-sport testing before going back to competition
How long does recovery take?
Return to pivoting sport after ACL reconstruction usually takes at least 9 to 12 months. Some people, particularly those not returning to pivoting sports, manage well with rehabilitation alone.
When to see a doctor
Seek prompt medical assessment after any knee injury with rapid swelling, inability to bear weight or a knee that locks.

Common questions
Do I need surgery for a torn ACL?
Not always. It depends on your sport, goals and how unstable the knee feels. We can help you weigh up the options with your surgeon.
When can I run after ACL surgery?
Commonly around three to four months, once strength and control tests are met.
Why does ACL rehab take so long?
The new graft takes many months to mature, and strength and control need to be rebuilt to reduce the risk of re-injury.
