You’ve had knee pain, an MRI and now the report says meniscus tear.
That one phrase can make it feel like your knee is broken. You might be wondering whether walking on it is making things worse, whether physiotherapy is just delaying the inevitable or whether surgery is the only real way to ‘fix’ it.
The honest answer is: it depends on the tear, the knee and the person.
Some meniscus tears respond well to physiotherapy. Others need a surgical opinion sooner. And even when surgery is the right choice, physiotherapy often still plays an important role before and after the procedure.
The right meniscus tear treatment depends on how the tear happened, whether your knee is truly locking, your symptoms, your goals and what your knee can actually do.
This is why individual assessment matters. An MRI can be useful, but it should not make the decision by itself.
In this article, you’ll learn when physiotherapy is usually the best first step, when surgery may be worth considering sooner and how to think about meniscus surgery vs physiotherapy without relying on the wording of your scan alone.
What is a meniscus tear?
Your meniscus is a C-shaped piece of fibrocartilage that sits between your thigh bone, or femur, and your shin bone, or tibia. Each knee has two menisci: one on the inside of the knee and one on the outside. They help absorb force, spread load through the knee and support normal joint movement.
A meniscus tear means part of this structure has been damaged.
This can happen suddenly, such as when you twist your knee during sport, change direction quickly or squat under load. It can also develop gradually over time as part of age-related change in the knee.
This is where language can get confusing.
People often call a meniscus tear a ‘knee cartilage injury’, but the meniscus is not the same as the smooth joint cartilage that covers the ends of your bones. Both matter, but they are different structures. So, if your scan says you have a meniscus tear, it does not automatically mean you have damaged the joint cartilage lining the knee.
Why the MRI is only one part of the picture
An MRI can show the location and pattern of a meniscus tear. It can also pick up other things that may matter, such as ligament injury, joint swelling or changes to the joint surfaces.
But an MRI is not the whole diagnosis.
Two people can have similar-looking tears on a scan and very different knees in real life.
One person may twist their knee during sport, develop swelling and struggle to straighten the knee. Another may have a gradual ache, no clear injury and an MRI that shows a degenerative meniscus tear.
Those two people may need different advice.
A good assessment looks at how your pain started, whether the knee locks, how much swelling you have, what movements bring on symptoms, how well you can walk, squat or climb stairs and what you need your knee to do for work, sport or daily life.
The scan matters. But the person matters too.
Meniscus surgery vs physiotherapy: what does the evidence say?
The strongest evidence is for degenerative meniscus tears.
These tears usually develop over time and are more common in middle-aged and older adults. Symptoms may start after a small twist, a squat, a longer walk than usual or sometimes with no obvious trigger.
In this group, research has repeatedly shown that surgery is not always better than a structured physiotherapy program. One major trial followed people with degenerative meniscus tears for five years and found that exercise-based physiotherapy was not inferior to arthroscopic partial meniscectomy for knee function. In plain English: for many people with this type of tear, physiotherapy can lead to similar long-term outcomes to surgery.
Guidelines also reflect this. The BMJ published a strong recommendation against arthroscopy for most people with degenerative knee disease, including degenerative meniscus tears. That does not mean surgery is never useful. It means routine arthroscopy for degenerative meniscus tears is not supported for most people.
But this is where nuance matters.
A degenerative tear in a stiff, sore knee is not the same as a young athlete who twists their knee, develops swelling and cannot straighten it properly. It is also not the same as a displaced tear that physically blocks the knee.
So the evidence does not say ‘never surgery’.
It says that for many non-locking and degenerative meniscus tears, physiotherapy is usually a sensible first step. Surgery becomes more relevant when the tear is mechanically blocking the knee, when symptoms are not improving with good rehabilitation or when the person’s injury, goals and assessment findings point towards a surgical pathway.
When physiotherapy first makes sense
Physiotherapy is often a good first step when your knee is painful, but not mechanically blocked.
That means you can still straighten and bend your knee, even if it feels sore, stiff, swollen or uncomfortable. You may have pain with stairs, squats, kneeling, running, walking longer distances or getting up from a chair, but the knee is not physically stuck.
Physiotherapy first is especially sensible when the tear looks degenerative, your symptoms started gradually or there was no major injury moment. In this situation, treatment is usually less about ‘fixing the tear’ and more about helping the knee settle, move better and tolerate more of what you need it to do.
It can also make sense after some acute meniscus injuries, depending on the tear pattern, swelling, movement, stability and your goals. Not every traumatic tear needs immediate surgery, but some tear types are more likely to need a surgical opinion.
A physiotherapy-first approach may be appropriate if your knee is not truly locked, swelling is mild or improving, pain changes depending on activity and there are no signs of a major associated injury such as significant instability or suspected ligament rupture.
The plan may include reducing irritating activities for a short period, managing swelling, restoring knee movement, strengthening the muscles around the knee and hip and gradually reloading the knee for work, sport or daily life.
If your knee improves with physiotherapy, you may not need surgery. If it does not improve, you have not necessarily ‘wasted time’. A good rehabilitation period can clarify what your knee responds to and give your GP, physiotherapist or surgeon better information to guide the next step.
What does physiotherapy for a meniscus tear involve?
Physiotherapy for a meniscus tear is not just a few stretches or a generic exercise sheet.
A good plan starts with understanding your knee properly. Your physiotherapist will usually look at how your symptoms started, what movements bring them on, how much swelling you have, whether your knee can fully straighten and bend, how well you can walk, squat or climb stairs and what you need to get back to.
From there, treatment may focus on calming the knee down, restoring movement, building strength and gradually returning to activity.
These things often happen together. You do not need to finish ‘movement’ before you start ‘strength’. Your physiotherapist may help you regain comfortable range of motion while also strengthening the muscles around the knee and hip in a way your knee can tolerate.
The goal is not just to make muscles stronger in isolation. It is to help your knee cope better with the things you actually need it to do.
For one person, that might mean walking the dog without swelling afterwards. For another, it might mean getting back to running, football, netball, gym training, kneeling at work or playing with their kids.
If surgery becomes the right option, physiotherapy can still matter. Before surgery, it may help settle symptoms and improve how well the knee is moving. After surgery, it usually plays an important role in rebuilding movement, strength and confidence.
When surgery may be needed sooner
Surgery is not the first step for every meniscus tear, but it does have a place.
A surgical opinion may be needed sooner if your knee is truly locked. This means the knee is physically blocked and you cannot fully straighten it. That is different from a knee that feels stiff, sore, clicky or hard to move because of pain or swelling.
A truly locked knee can happen when part of the meniscus moves into the joint and blocks normal movement. This is sometimes seen with a displaced tear, such as a bucket-handle tear.
A surgical opinion may also be worth considering sooner if you had a clear traumatic injury, your knee swelled significantly after the injury, the knee keeps giving way, there is concern about another injury such as an ACL tear or your symptoms are not improving after a structured rehabilitation period.
Seeing a surgeon does not automatically mean you will have surgery. It means you are getting another opinion on whether the tear pattern, your symptoms and your goals point towards a surgical pathway.
For acute meniscus tears that may be repairable, timing can matter. A 2025 systematic review found that earlier meniscal repair was associated with higher success rates than delayed repair, but the authors also noted that there is currently no high-quality evidence on the best timing for repair. This does not mean every acute meniscus tear needs surgery straight away, but it does mean a suspected repairable tear should be assessed early.
How long should you try physiotherapy before considering surgery?
There is no perfect number of weeks that applies to every meniscus tear.
For many non-locking or degenerative meniscus tears, it is reasonable to give physiotherapy a proper trial before considering surgery. In many cases, that means reassessing after around 6 to 12 weeks of consistent rehabilitation.
But this does not apply to every situation. If your knee is truly locked, you cannot straighten it, you have major swelling after an injury, your knee keeps giving way or there is concern about another injury such as an ACL tear, you should be assessed sooner.
The word ‘consistent’ also matters.
Doing two exercises once a week and hoping the knee changes is very different from following a clear plan, adjusting the activities that keep stirring it up and gradually rebuilding what the knee can tolerate.
Your progress should be judged by more than pain alone. Your physiotherapist may look at whether swelling is settling, movement is improving, walking or stairs feel easier, flare-ups are less frequent and you are getting closer to the activities you care about.
If those things are improving, staying with physiotherapy may make sense.
If your knee is not improving despite a good rehabilitation plan, it may be time to review the diagnosis and consider whether a surgical opinion is needed.
When should you get your knee assessed quickly?
Most meniscus-related knee pain is not an emergency. But some symptoms should be checked quickly because they may point to a more serious injury or a problem that needs medical care.
For non-emergency knee pain, a physiotherapist or GP can assess your knee and refer you on if needed.
But if you have red flags such as severe pain, major swelling after an injury, a hot red knee with fever, a visibly deformed knee, calf swelling or you cannot weight-bear, seek urgent medical care through a hospital emergency department.
A locked knee is also important in the context of a possible meniscus tear. This is not just a stiff or painful knee. It means something is physically stopping the knee from straightening, which can happen with certain displaced meniscus tears.
So, surgery or physiotherapy first?
For many meniscus tears, physiotherapy is a sensible first step.
This is especially true if your knee is not truly locked, your symptoms are manageable and the tear appears degenerative or related to age-related change in the knee.
But surgery still has a place.
If your knee is physically blocked from straightening, the tear may be repairable, there was a clear traumatic injury, your knee is unstable or your symptoms are not improving with appropriate rehabilitation, it may be worth getting a surgical opinion sooner.
The key is not choosing surgery or physiotherapy based on fear, guesswork or one line in an MRI report. The key is getting your knee assessed properly so the plan matches the type of tear, your symptoms, your goals and the person behind the injury.
