A painful, swollen or catching knee after a twist can be a sign of a meniscus tear. Meniscal injuries are common, but the symptoms can overlap with a sprain, osteoarthritis or damage to another knee structure. The good news is that many meniscus tears improve without an operation, although recovery often takes longer than people expect.
Start with a free initial consultation
Your free initial consultation lets you meet the physiotherapist, describe your symptoms and understand how the service works before choosing any paid treatment. We can discuss how the injury happened, what your knee can currently do and whether physiotherapy is an appropriate next step.

Paid physiotherapy sessions are optional and secondary. There is no obligation to book treatment after the free consultation.
What is a meniscus tear?
Each knee has two menisci: strong, crescent-shaped pads of fibrocartilage between the thigh bone and shin bone. They help spread load and absorb shock as you walk, turn, squat and run.
A tear can happen suddenly when the knee twists during sport, but it can also follow a smaller movement such as turning while standing up. With age, the meniscus can become less resilient, so symptoms may appear after an ordinary movement or build gradually without a dramatic injury.
Common symptoms of a torn meniscus
According to the NHS, possible symptoms include:
- Pain or tenderness around the knee joint line
- Stiffness or swelling, which may not appear until hours or days later
- Difficulty bending or fully straightening the knee
- The knee giving way when you stand or walk
- Clicking, crunching or catching during movement
A click by itself does not confirm a tear, and a scan result does not always explain pain. Assessment should consider how the injury happened, where the pain is, swelling, movement, strength, stability and the activities you need to return to.
Does “locking” matter?
A brief catch or hesitation is different from a knee that is physically stuck and cannot fully bend or straighten. The NHS advises urgent GP or NHS 111 help if you cannot bend or straighten your leg.
What should you do in the first few days?
Stop the activity that caused the injury and reduce movements that sharply increase pain. NHS self-care advice includes resting the knee when possible, elevating it, and applying an ice pack wrapped in a towel for up to 20 minutes every two to three hours. A bandage or knee support may help some people, but it should be removed for sleep.
Do not place ice directly on the skin. During the early stage, the NHS advises avoiding heat packs, hot baths, massage, alcohol and heavy carrying. Complete immobility is not usually the aim: after a few days of relative rest, begin gentle knee movement within a comfortable range if you can.
Ask a pharmacist or GP which pain relief is suitable for you. Anti-inflammatory medicines such as ibuprofen are not appropriate for everyone, particularly with certain stomach, kidney, heart or asthma conditions, during pregnancy, or alongside some medicines.
Can a meniscus tear heal without surgery?
Yes, many tears improve without surgery. The NHS states that a meniscus tear can get better on its own, although it may take time. Whether the tissue itself heals depends partly on the tear’s location, pattern, blood supply and any other knee injury. Importantly, people can often regain good function even when a tear remains visible on imaging.
For degenerative meniscal tears, an NHS musculoskeletal service advises that many people notice significant improvement within three to six months of starting rehabilitation, while some take up to a year. An acute sports injury may follow a different timeline. Recovery should therefore be based on symptoms and function rather than a promised date.
What does physiotherapy involve?
Physiotherapy may be recommended to reduce pain and improve knee movement and strength. A tailored programme commonly progresses through:
- Settling irritation: adjusting activity and restoring comfortable bending and straightening.
- Rebuilding strength: gradually loading the thigh, hamstring, calf and hip muscles.
- Improving control: balance, step, squat and single-leg tasks appropriate to your goals.
- Returning to activity: progressive walking, stairs, work duties, gym training, running or sport.
Progress is rarely perfectly linear. A small, short-lived symptom increase after a new exercise does not automatically mean further damage, but sharp pain, increasing swelling, repeated giving way or loss of movement means the plan should be reviewed.
If your main symptom is gradual knee pain rather than a clear twisting injury, our guide to knee osteoarthritis and exercise may also be relevant. Runners can also read what to do when knee pain appears after running.
Do all meniscus tears need an MRI?
No. A clinician may be able to form an initial management plan from the history and examination. Imaging can be useful when the diagnosis is uncertain, symptoms are severe or mechanical, another injury is suspected, or surgical review is being considered. A scan should be interpreted alongside your symptoms because meniscal changes can also be found in people who do not have knee pain.
When might surgery be considered?
Surgery is not automatic. The NHS says arthroscopy may be needed when damage is severe, either to repair the meniscus or remove a damaged portion. The decision depends on factors such as the tear pattern, true locking, associated ligament injury, age, activity needs and response to rehabilitation.
NICE notes that minor meniscal damage can be managed conservatively with rest and physical therapies, while repair is only possible for some tears depending on their location, pattern and other joint damage. If surgery is recommended, rehabilitation is still important afterwards.
When should you seek medical help?
- Contact a GP if pain disrupts normal activities or sleep, is worsening or recurring, or has not improved with self-care.
- Use urgent GP care or NHS 111 for very severe pain after an injury, inability to walk or bear weight, a hot swollen knee, fever or shivering, or inability to bend or straighten the leg.
- Go to A&E if the knee has changed shape or moved out of place, or if you have tingling or loss of feeling in the knee, leg or toes.
Ready to plan your recovery?
A clear plan should reflect your symptoms, daily demands and goals — whether that means comfortable walking, returning to work, training in the gym or getting back to sport.
