The meniscus is one of the most commonly injured parts of the knee, but knowing whether you have actually done yours can be confusing. Is it a serious tear, or just a tweak? The truth is there are some fairly reliable signs of a meniscus injury, and knowing them helps you decide what to do next.
In this guide we explain what a meniscus injury is, how it happens, the signs of a meniscus tear, and when to see a physiotherapist about your knee pain.
What Is a Meniscus Injury?
It is damage to one of the two wedges of cartilage that cushion and stabilise your knee. A meniscus tear can range from a small, minor tear to a larger one that affects how the knee moves. Because the meniscus absorbs load and helps the joint glide smoothly, damage here can cause pain, swelling and mechanical symptoms.
How a Meniscus Injury Happens
There are two main ways it occurs. The first is a sudden twist or pivot on a planted foot, common in sport, which tears an otherwise healthy meniscus. The second is gradual wear over time, where the cartilage weakens with age and tears with little force. Knowing which type you have influences what happens next.
Signs You Have a Meniscus Injury
So how do you know? Typical signs include knee pain along the joint line, swelling that develops over hours, and pain with twisting, squatting or deep bending. Some people feel clicking, catching, or the knee locking or giving way. If your knee pain fits this pattern after a twist, it is a real possibility.
Acute vs Degenerative Tears
Not every meniscus tear is the same. An acute tear from a specific twisting injury behaves differently from a degenerative tear that develops gradually with age. Younger, sporty people tend to get acute tears, while degenerative tears are common from midlife onwards and often sit alongside early joint changes. This distinction shapes treatment.
Diagnosing a Meniscus Injury
Diagnosis starts with your history and a physical examination, where specific tests load and rotate the knee to reproduce your symptoms. Imaging such as an MRI can confirm a meniscus tear and show its size and type, though many tears are managed well without one. A good assessment often gives a strong indication on its own.
What Happens Next?
The reassuring truth is that many of these injuries do not need surgery. Plenty settle well with a structured rehabilitation program that reduces pain and rebuilds strength, particularly degenerative tears. You can read more about this in our guide on managing a meniscus injury. Others, especially certain acute tears causing locking, may benefit from surgical review. The right path depends on your tear, your knee and your goals.
When to See a Physiotherapist
It is worth seeing a physiotherapist if you have ongoing knee pain, swelling or mechanical symptoms after a twist or over time. They can assess the knee, give you a likely diagnosis, and start the right plan. Seek prompt care if your knee locks and will not straighten, or gives way repeatedly, as these need timely assessment.
Common Questions About Meniscus Injuries
How do I know if I have a meniscus injury?
Common signs are joint-line knee pain, swelling over hours, and pain with twisting or squatting, sometimes with clicking, catching or locking, especially after a twisting injury.
What does a meniscus tear feel like?
Often a deep knee pain on the inside or outside of the joint, worse with twisting or deep bending, sometimes with catching, locking or a sense the knee may give way.
Do I need surgery?
Not necessarily. Many settle with rehabilitation, especially degenerative tears. Some acute tears may need surgical review. It depends on your specific injury.
Will it heal on its own?
Some tears settle with the right rehab, while others do not fully heal but become manageable. Your physiotherapist or surgeon can guide what to expect.
How does physiotherapy help?
Physiotherapy assesses the knee, reduces pain and swelling, rebuilds strength and control, and guides your return to activity, often without the need for surgery.
