All you need to know about ACL injuries

What is an ACL?

Your anterior cruciate ligament (ACL) runs through the centre of your knee to connect your thigh bone (femur) to your shin bone (tibia).

ACL injuries occur when the leg twists or hyperextends under force. Abrupt changes in direction are a common cause of ACL injuries. Football, rugby and basketball are just some of the sports that place a high demand on the ACL with their cutting and sharp directional changes.

Any tearing or rupture (where the ligament severs in half) makes the knee unstable. You’ll have to put a stopper on your universally adored dance moves and sporting exploits until you get it sorted.

What does an ACL injury feel like?

You may hear or feel something pop and then feel sudden pain and weakness in your knee.

I think I injured my ACL. What do I do next?

The level of pain you feel will probably tell you whether you go straight to emergency hospital or head home to organise a physio or doctor appointment.

While ACL damage might be your first thought, the ACL is just one of four ligaments that supports the knee. Add to that potential damage to the meniscus that provides the cushion for the knee joint to function smoothly without bone-on-bone contact. Not to mention the surrounding muscles that can tear and bones that can suffer fractures and breaks.

In short, self-diagnosis probably isn’t an option.

So you’ll need some help. Here is your next choice: hospital or head home.

  1. Emergency department The doctors at emergency will assess you and provide you with your next steps.
  2. Head home to plan your next move Elevate your leg and keep it at a comfortable angle, perhaps with a pillow under your knee. 

To ice or not to ice? 

Many physios still advise applying ice to your injury straight away. 

Ice eases pain, swelling and discomfort, especially if applied shortly after the injury occurs. Pain and discomfort may be your biggest concerns early on in an injury, so it’s well worth considering.

The doubt that has been rising is whether ice delays the healing process. Some studies show that ice may delay the natural healing process for ankle injuries. Just be aware that the standards for treating injuries may change in future as more evidence comes out.

GP or physio?

One of the advantages of visiting a GP first is that they can refer you to an MRI scan covered for free under Medicare while a physio cannot.

Once your doctor checks your results, you can see what damage has been done and whether surgical options are needed or worthwhile.

From there your doctor can advise you if you’re ready for physio treatment. Just be prepared to check in your pride at the door. You may not realise it yet, but your physio thinks your glutes, quads, calves and hamstrings are the most pathetic cluster of underused muscles on the planet. 

What is an ACL repair?

An ACL repair (also called ACL reconstruction) is an operation that seeks to return your ACL to full function by adding a tendon graft from elsewhere your body and using it to reconnect your broken ACL.

Not all ACL injuries require surgery. Some people with ruptured ACLs may choose not to have them repaired if they give up sports with lots of directional changes. Your doctor will have more information specific to your situation.

ACL repairs in Australia increased per head of population by 43% from 2000 to 2015, according to The Medical Journal of Australia. Australia has the highest rate of ACL repairs in the world.
