A meniscus injury is one of the most common knee problems, and it can leave you wondering whether you have done something serious. The good news is that many meniscus injuries settle well, often without surgery. Knowing the signs helps you work out what you are dealing with and what to do next.
In this guide we explain what the meniscus is, the signs of a meniscus injury or meniscus tear, what causes the knee pain, and how physiotherapy helps you recover, plus when a scan or surgery might be needed.
What Is the Meniscus?
The meniscus is a pair of C-shaped pieces of cartilage that sit between your thigh bone and shin bone, one on each side of the knee. They act as shock absorbers and help spread load across the joint, keeping your knee stable and cushioned. Because they take so much load, they are a common site of injury.
What Is a Meniscus Injury?
A meniscus injury is damage to that cartilage, ranging from a small tear to a larger one. It can happen suddenly, often with a twist of the knee, or develop gradually as the cartilage wears with age. Not all meniscus injuries are the same, and importantly, many do not need surgery to get better.
What Causes a Meniscus Tear?
There are two broad types. A traumatic meniscus tear usually happens with a forceful twist or pivot, common in sport, sometimes alongside other knee injuries. A degenerative meniscus tear develops slowly over time as the cartilage naturally wears, and is more common as we get older, sometimes without any clear injury at all. Knowing which type you have shapes the best approach.
Signs You Might Have a Meniscus Injury
Common signs of a meniscus injury include knee pain, especially along the joint line, swelling that develops over hours to a day, and stiffness. Many people notice catching, clicking or a sense of the knee giving way. In some cases the knee can lock, where it gets stuck and will not fully straighten, which is worth getting assessed promptly. Twisting, squatting and pivoting often make the knee pain worse.
How Is a Meniscus Injury Diagnosed?
A physiotherapist can usually get a good picture from your history and a hands-on assessment, using specific knee tests to gauge whether the meniscus is involved. This clinical assessment guides the plan. Imaging is not always needed, and we will come back to that below.
Do You Need a Scan or Surgery?
This surprises many people: a scan is not always necessary, and surgery is often not the first answer. Meniscus tears frequently show up on scans in people with no pain at all, so a scan does not always change the plan. For most meniscus injuries, especially degenerative ones, research supports starting with physiotherapy rather than surgery. Surgery is considered in specific cases, such as a locked knee or when a well-run rehab program has not helped, and that decision is made with a surgeon.
How a Meniscus Injury Is Treated
For most people, treatment begins with physiotherapy. Early on, the focus is settling knee pain and swelling and restoring movement. From there, the priority is rebuilding the strength and control of the muscles around the knee, which take load off the joint and get you back to activity. A gradual, guided return to your sport or daily life rounds it out. Many meniscus injuries recover well with this approach, no operation required.
Common Questions About Meniscus Injuries
Can a meniscus tear heal on its own?
It depends on the type and location. The outer meniscus has a blood supply and can heal, while the inner part heals poorly. Even when the tear itself does not fully heal, symptoms often settle well with physiotherapy.
Should I get a scan?
Not always. Meniscus tears are common on scans even in pain-free knees, so a scan does not always change treatment. Your physiotherapist or doctor can advise whether imaging would actually be useful.
Do I need surgery for a meniscus tear?
Often not. For most tears, especially degenerative ones, physiotherapy is the recommended first step. Surgery is reserved for specific situations and is decided with a surgeon.
How long does a meniscus injury take to recover?
It varies with the type and severity, but many settle over several weeks to a few months with the right rehab. Sticking with your strengthening program makes a big difference to your knee pain and function.
When should I see a physiotherapist?
See a physiotherapist if you have knee pain, swelling, catching or giving way, or if your knee locks. Early assessment helps you recover faster and avoid unnecessary scans or surgery.
