Meniscus Tears: Recovery, Physiotherapy & When Surgery May Help

Does every meniscus tear need an operation?

No. Many people improve with appropriate non-surgical care. Others need an early specialist opinion, particularly after an acute injury with a displaced tear or a knee that is physically locked.

The decision depends on how the injury happened, the tear pattern, knee function, associated damage and your goals. A scan finding on its own does not decide treatment.

What is the meniscus?

Each knee has two menisci: the medial meniscus on the inside and the lateral meniscus on the outside. These crescent-shaped fibrocartilage structures help distribute load and support joint function.

What symptoms might you notice?

• Pain with walking, turning, squatting or other loaded movements.
• Swelling or stiffness.
• Tenderness near the joint line.
• Catching, giving way or difficulty fully bending or straightening.

These symptoms have several possible causes. Painless clicking is common and does not, by itself, mean surgery is necessary.

How is a meniscus injury diagnosed?

Your clinician considers the onset, symptoms and examination findings, including movement, tenderness and stability. They also assess for other sources of knee pain or associated injury.

Will you need a scan?

Not every suspected tear needs immediate imaging. MRI is generally preferred when imaging is needed for an acute meniscal injury. X-rays may answer questions about bone injury or arthritis rather than showing the meniscus itself.

Ultrasound has uses around the knee but should not be presented as a routine replacement for MRI when assessing deeper meniscal damage.

Can a meniscus tear improve without surgery?

Symptoms and function may improve with rehabilitation even when the tear has not structurally healed. Recovery and tissue healing are related but different outcomes.

Blood supply is generally better towards the outer meniscus than the inner part. Location matters, but it is only one factor: the size, shape, displacement and associated injuries also influence decisions.

A bucket-handle tear is a displaced longitudinal tear, not simply a large horizontal tear. Different tear names do not automatically translate into “must operate” or “never operate”.

What does non-surgical treatment involve?

1. Adjust painful activities: reduce twisting, deep loaded bending or impact if these provoke symptoms.
2. Manage discomfort: discuss suitable pain relief and symptom-management measures.
3. Restore movement: work towards comfortable knee mobility.
4. Build strength: progress relevant knee and hip exercises.
5. Review function: assess walking, stairs and your intended activities.

Walking may be reasonable if comfortable and allowed by your clinician. Inability to bear weight or a blocked knee needs assessment rather than forcing activity.

What does the evidence say about physiotherapy and surgery?

The 2013 METEOR trial compared surgery plus rehabilitation with a physiotherapy programme in adults aged 45 or older who had a meniscal tear and mild-to-moderate knee osteoarthritis.

On the primary analysis, functional improvement was not significantly different between the groups at six months. Some patients initially allocated to physiotherapy later had surgery.

This supports discussing rehabilitation in that patient group. It does not mean physiotherapy and surgery are interchangeable for every acute tear, particularly a displaced tear causing restricted movement.

When might surgery be considered?

Urgent assessment is appropriate for a locked knee. A specialist may also consider early surgery for selected acute tears with repair potential, or further investigation when symptoms persist despite appropriate care.

Current acute-tear guidance emphasises preserving as much functioning meniscus as possible. Surgery involves risks and rehabilitation, and should follow an individual discussion.

Can an injection heal a torn meniscus?

An injection should not be described as stitching a tear together or guaranteeing cartilage repair. In selected patients, an injection may be discussed for associated pain or inflammation, with its purpose and limitations explained.

Steroid, hyaluronic acid and platelet-rich plasma are different treatments with different evidence. They should not be grouped together as proven remedies for every meniscal tear.

Ask what problem the proposed injection targets, what benefit is realistic, what risks apply and whether the evidence relates to your specific condition. An injection should not delay assessment of a locked knee.

How long does recovery take?

There is no fixed six-month recovery rule. Progress depends on the injury, symptoms, treatment and activity demands. A repaired meniscus may require specific restrictions that differ from non-operative care or trimming.

Return to sport should be based on the treating team’s guidance and functional progress. Persistent swelling, locking, giving way or worsening pain warrants review.

When to seek urgent help

Contact NHS 111 for severe pain after injury, inability to walk or bear weight, a knee you cannot bend or straighten, or a hot swollen knee with fever or shivering. Go to A&E for deformity or new loss of feeling after injury.
