A meniscus tear is a common knee injury that can occur during sport, after a twisting movement or gradually as the meniscus changes with age. Symptoms range from mild pain and swelling to catching, locking or difficulty fully moving the knee.
At YOS Health London Bridge, physiotherapy can help assess knee symptoms, restore strength and movement, and develop a progressive rehabilitation programme based on your goals and the type of meniscal problem.
What is the Meniscus?
Each knee contains two menisci: a medial meniscus on the inner side of the knee and a lateral meniscus on the outer side. These crescent-shaped structures sit between the thigh bone and shin bone.
The menisci help distribute load through the knee, contribute to joint stability and assist with movement and shock absorption. Because different parts of the meniscus have different blood supplies, healing potential can vary depending on where a tear occurs.
What is a Meniscus Tear?
A meniscus tear occurs when the tissue is damaged. In younger or highly active people, tears can occur following a forceful twisting or pivoting movement, particularly when the foot is planted. In older adults, the meniscus can become more vulnerable to tearing as part of age-related changes in the knee.
Meniscal tears have different shapes and patterns. The clinical significance of a tear is therefore not determined by the scan report alone. Symptoms, physical examination and how the knee functions are important when deciding on appropriate treatment.
Common Causes of Meniscus Tears
Meniscus injuries can occur suddenly or develop gradually.
Acute sports injuries
- Twisting or pivoting with the foot planted
- Sudden changes of direction
- Deep squatting under load
- Contact or collision during sport
- Landing awkwardly from a jump
Degenerative changes
With increasing age, the meniscus may undergo structural changes that make it more susceptible to tearing. In these situations, symptoms can sometimes develop without one clearly identifiable injury.
Meniscus Tear Symptoms
Symptoms depend on the type and location of the tear and how the knee responds to loading. Common symptoms include:
- Knee pain, particularly around the joint line
- Swelling or stiffness
- Pain with twisting or turning
- Pain during squatting or stairs
- Difficulty fully bending or straightening the knee
- Catching or clicking sensations
- A feeling that the knee is unstable or gives way
- Reduced confidence during running or sport
Not every click or painful sensation means that a meniscus is torn. Knee symptoms can have several possible causes, so an appropriate assessment is important.
Can a Meniscus Tear Cause Knee Locking?
Some meniscal injuries can cause catching or a sensation of locking. However, it is important to distinguish between pain-related restriction, where movement is limited because the knee is painful or swollen, and a true mechanical block where the knee cannot move through part of its normal range.
How is a Meniscus Tear Diagnosed?
Diagnosis begins with a detailed history and physical examination. A clinician may assess the location of pain, swelling, range of movement, strength, walking pattern and specific knee movements that reproduce symptoms.
MRI can provide detailed information about the menisci and other structures inside the knee. However, imaging findings need to be interpreted alongside symptoms and clinical examination because meniscal changes can also be present in people without significant symptoms.
Meniscus Tear Treatment
Treatment is individualised. Many people can initially be managed without surgery, particularly when symptoms are improving and there is no persistent mechanical obstruction.
1. Activity modification
Activities that significantly aggravate the knee may need to be temporarily modified. This does not necessarily mean complete rest. Maintaining appropriate movement and general fitness can be helpful while the knee settles.
2. Physiotherapy
Physiotherapy focuses on restoring knee function and improving the capacity of the muscles around the knee and hip. Rehabilitation can address strength, balance, movement control and the specific demands of work or sport.
3. Pain and swelling management
Early rehabilitation may include strategies to manage pain and swelling while maintaining comfortable movement. Your clinician can advise on appropriate activity levels and progression.
4. Progressive strengthening
Strengthening the quadriceps, hamstrings, gluteal muscles and calf can help restore lower-limb capacity. Exercises are progressed according to symptoms and functional goals.
5. Return-to-sport rehabilitation
For athletes, rehabilitation eventually needs to address running, deceleration, changes of direction, jumping and other sport-specific demands. These should be introduced progressively rather than immediately returning to full training.
Exercises for a Meniscus Tear
The right exercises depend on the stage of recovery, symptoms and type of injury. Common rehabilitation exercises may include:
Quadriceps contractions
Gentle quadriceps activation can help maintain muscle engagement when the knee is painful or swollen.
Straight-leg raises
Once appropriate, straight-leg raises can help develop quadriceps control without requiring repeated knee bending under load.
Bridges
Bridges strengthen the posterior chain and can be progressed as knee tolerance improves.
Mini squats
Controlled partial squats can gradually reintroduce weight-bearing knee flexion. Depth and resistance should be progressed according to symptoms.
Step-ups
Step-ups provide a functional strengthening exercise and can be progressed by increasing step height, repetitions or resistance.
Single-leg balance
Balance exercises can help restore lower-limb control and confidence before progressing towards more demanding activities.
Do not use a generic exercise programme as a substitute for assessment. A painful or swollen knee may require modification of exercise selection, range or loading.
Does Every Meniscus Tear Need Surgery?
No. Treatment decisions depend on several factors, including symptoms, tear characteristics, age, activity requirements, previous treatment and whether there is persistent mechanical locking.
Physiotherapy may be appropriate as part of conservative management. If symptoms do not improve adequately or there is a specific indication for surgery, an orthopaedic assessment may be recommended.
Meniscus Surgery and Physiotherapy
When surgery is recommended, physiotherapy is commonly an important part of recovery. The rehabilitation programme depends on the procedure performed and any restrictions provided by the surgical team.
After an arthroscopic procedure, rehabilitation may focus on restoring knee movement, reducing swelling, rebuilding strength and progressively returning to normal activities. Following a meniscal repair, progression may be more cautious because the repaired tissue needs appropriate protection while healing.
How Long Does a Meniscus Tear Take to Recover?
Recovery time varies significantly. A person with a relatively mild, stable injury managed conservatively may progress differently from someone who has undergone meniscal repair.
Useful markers of progress include:
- Reduced pain and swelling
- Improved knee movement
- Restored quadriceps and lower-limb strength
- Improved ability to walk, squat and use stairs
- Increasing tolerance to running or other impact
- Successful completion of sport-specific movements
Rather than focusing only on a fixed number of weeks, rehabilitation should progress according to symptoms, strength, movement and functional capacity.
Returning to Running After a Meniscus Tear
Running should generally be reintroduced once the knee has sufficient movement, strength and load tolerance. A graded programme may progress from walking to jogging and then gradually increase running volume.
- Restore comfortable daily walking.
- Regain knee movement and basic strength.
- Build single-leg strength and control.
- Introduce low-level impact activities.
- Begin controlled running.
- Gradually increase running distance and intensity.
- Reintroduce changes of direction, hills and sport-specific drills.
Increasing several training variables at once can make it difficult to judge how the knee is responding. Progressing one variable at a time can make load management easier.
When Should You See a Physiotherapist?
Consider an assessment if you have persistent knee pain, swelling, reduced movement, difficulty returning to exercise, or symptoms that repeatedly recur when activity increases.
A physiotherapist can assess your knee and help determine whether rehabilitation is appropriate, whether further medical assessment is warranted, and how to progress your activity safely.

Frequently Asked Questions
Can a meniscus tear heal without surgery?
Some meniscal injuries can be managed without surgery, depending on the type and location of the tear, symptoms and functional limitations. A clinical assessment helps determine the most appropriate approach.
Can I walk with a meniscus tear?
Many people can walk with a meniscus injury, although pain, swelling or reduced movement may make walking difficult initially. Activity should be adjusted according to symptoms and clinical advice.
Should I exercise with a meniscus tear?
Appropriate exercise is often an important part of rehabilitation, but exercises should be selected and progressed according to the individual's symptoms and stage of recovery.
How do I know if my knee is really locked?
A true locked knee involves an inability to fully move the knee through its normal range, rather than simply stopping because movement is uncomfortable. Persistent mechanical locking should receive prompt medical assessment.
Is MRI always needed for a meniscus tear?
No. The need for MRI depends on the clinical presentation and whether imaging would change management. A clinician can determine whether further investigation is appropriate.
When can I return to sport after a meniscus tear?
Return to sport depends on the injury, treatment and recovery. Strength, movement, impact tolerance and sport-specific ability should be considered rather than relying on a fixed date.
