Do I actually need ACL surgery?

What matters is whether your knee is genuinely unstable in the life you actually lead.

An ACL tear is a finding on a scan. It is not, on its own, a reason to operate.

A completely torn ACL has limited ability to restore its original function on its own. But plenty of people live, work and exercise well without reconstruction.

The important question is stability.

If your knee genuinely gives way when you turn, land, change direction or step awkwardly, that instability matters. Repeated episodes can increase the risk of associated meniscus and cartilage injuries.

That is an important reason to consider reconstruction.

But if your knee remains stable and your activities are mainly straight-line activities such as walking, cycling or swimming, reconstruction may not be necessary.

We would rather establish that properly through examination and rehabilitation than book you for an operation simply because the MRI says “ACL tear.”

What we look at

Not your age first.

What do you want your knee to do?

A 55-year-old who plays badminton three mornings a week may have a stronger reason for reconstruction than a 28-year-old who does not participate in pivoting sports.

We also consider:

• what your sport or activity demands
• whether the knee has actually given way
• how often it has happened
• whether the meniscus or cartilage is also injured
• your strength and movement
• how the knee behaves once swelling has settled
• how you respond to a structured rehabilitation program

What happens if you wait?

The torn ligament itself is not the main concern.

The concern is instability.

If the knee repeatedly gives way, those episodes can place the meniscus and cartilage at risk.

If the knee remains stable, rehabilitation and observation may be entirely reasonable.

So the answer is simple:

If your knee is giving way, waiting is not a neutral choice. If it is not, waiting may be exactly the right choice.
