A physiotherapist checks the knee joint line during a meniscus tear assessment.

A meniscus tear is a knee cartilage injury that can cause joint-line pain, swelling, stiffness, catching, or locking. It may happen with a sudden twist, or it may build over time as the knee handles repeated load.

Meniscus symptoms can overlap with other causes of knee pain and sports knee injuries. A clear assessment helps decide whether you need load control, rehabilitation, medical review, or surgical opinion.

What Is a Meniscus Tear?

A meniscus tear is damage to one of the two crescent-shaped cartilage pads inside the knee. Each knee has a medial meniscus and a lateral meniscus. These structures help absorb shock, spread load, guide movement, and support knee stability.

A tear can occur when the knee twists under load. This is common in sports that involve pivoting, tackling, jumping, or quick changes of direction. Some tears develop more slowly with age-related tissue change, repeated squatting, or long-term knee overload.

What Are the Symptoms of a Meniscus Tear?

Meniscus tear symptoms vary with the tear type, size, and location. Many people notice joint-line pain, swelling after activity, stiffness, and a feeling that the knee does not move smoothly.

Symptoms often worsen with twisting, squatting, kneeling, getting out of a chair, or going up and down stairs. Catching, locking, or a blocked feeling can suggest that the torn tissue is interfering with knee movement.

How Do You Know if You Have a Meniscus Tear?

You may have a meniscus tear if knee pain sits along the joint line and worsens with twisting, squatting, or pivoting. Swelling, catching, locking, or trouble straightening the knee can also fit this injury.

Other knee problems can feel similar. These include an ACL injury, MCL tear, runner’s knee, and patellofemoral pain syndrome. A physiotherapist or doctor can check your history, swelling pattern, joint-line tenderness, range of motion, and movement response.

Imaging such as MRI may help when the diagnosis is unclear, symptoms persist, the knee locks, or surgery is being considered. Imaging results need clinical context because some meniscus findings can appear even when they are not the main pain driver.

Can a Meniscus Tear Heal on Its Own?

Some meniscus tears settle well without surgery. Healing depends on the tear location, tear stability, your age, your activity goals, and whether the knee is locking or repeatedly flaring.

Tears in the outer blood-supply region, often called the red zone, have better healing potential. Tears in the inner white zone heal less reliably. Even so, not every white-zone tear needs surgery. Many people improve with load control, strength work, and a staged return to activity.

How Is a Meniscus Tear Treated?

Treatment depends on your symptoms, tear type, function, and goals. Physiotherapy is often the first step for stable or degenerative tears because it can reduce pain, restore motion, improve strength, and build confidence with walking, stairs, work, and sport.

Rehabilitation often includes knee exercises, quadriceps and hamstring strengthening, hip control, calf strength, balance work, swelling management, and movement retraining. A staged plan helps you load the knee without repeatedly stirring it up.

If pain is mostly at the front of the knee, your assessment may also consider kneecap-related problems such as chondromalacia patella or patellofemoral pain. If symptoms feel more general and stiff, knee arthritis may also be part of the picture.

When Is Surgery Needed for a Meniscus Tear?

Surgery may be considered when the knee repeatedly locks, symptoms continue despite good rehabilitation, or the tear pattern is unlikely to improve without surgical input. Traumatic tears, flap tears, and unstable bucket-handle tears may need orthopaedic review sooner.

Knee arthroscopy may be used to assess, repair, or trim the torn meniscus when appropriate. Structured rehabilitation still matters whether surgery is used or not. Good strength, motion, and load control help protect your recovery pathway.

What Happens After Meniscus Surgery?

Post-operative physiotherapy helps restore knee extension, flexion, strength, balance, and confidence. Your plan will depend on whether the meniscus was repaired or partly removed, plus your work and sport demands.

Early rehabilitation usually focuses on swelling control, walking quality, range of motion, and muscle activation. Later stages build strength, hopping, running, direction change, and sport-specific or job-specific capacity as healing allows. A repair usually needs a more cautious timeline than a partial meniscectomy.

Can You Keep Exercising with a Meniscus Tear?

You can often keep exercising if the knee is not locking, swelling strongly, or getting worse after each session. The safest choice is usually low-irritation exercise that keeps pain mild and settles within 24 hours.

Good options may include bike work, pool exercise, controlled strength training, and carefully chosen knee treatment exercises. Avoid repeated twisting, deep loaded squats, or hard pivoting until your knee has been assessed and your symptoms are controlled.

Meniscus Tear FAQs

Can you walk on a torn meniscus?

Yes, many people can still walk on a torn meniscus, especially if the tear is small or stable. Walking does not rule out a meniscus injury. Pain, swelling, catching, or locking after activity still deserves assessment.

Does a meniscus tear always need surgery?

No. Many meniscus tears improve with rehabilitation, especially when the knee is not locking and symptoms are settling with better strength, movement, and load control. Surgery is more likely when symptoms persist or the tear is mechanically unstable.

What does a meniscus tear feel like?

A meniscus tear often feels like pain along the inner or outer joint line. It may also cause swelling, stiffness, discomfort with twisting or squatting, clicking, catching, or a blocked feeling in the knee.

How long does a meniscus tear take to recover?

Recovery time varies with the tear type, your baseline strength, and whether surgery is needed. Some people improve over several weeks with physiotherapy. Others need a longer rehabilitation timeline, especially after repair surgery.

When should you worry about a meniscus tear?

Seek prompt review if the knee locks, gives way repeatedly, becomes very swollen, cannot fully straighten, or keeps worsening. These features may suggest a more significant tear or another internal knee injury.

Can physiotherapy help a meniscus tear?

Physiotherapy can help many people with a meniscus tear by improving swelling control, knee movement, strength, balance, and load tolerance. It can also help identify when symptoms need medical or orthopaedic review.

What Should You Do Next for a Meniscus Tear?

If knee pain, swelling, catching, or locking is limiting your activity, an early assessment can help clarify the likely cause. A physiotherapist can check whether your symptoms fit a meniscus tear, a ligament injury, kneecap pain, or another source of knee pain.

If your knee repeatedly locks, you cannot fully straighten it, or symptoms keep worsening, seek medical review sooner rather than later. For less severe symptoms, a guided rehabilitation plan can help you rebuild knee strength and return to activity with more confidence.
