Torn Meniscus: Causes, Symptoms & Treatment in Canada

A torn meniscus is one of the most common knee injuries affecting Canadians of all ages, from young hockey players to older adults dealing with everyday wear and tear. Whether the tear happens during a sudden twist on the ice or while simply crouching to pick something up, the pain and limited mobility can significantly impact your daily life.

How Is a Torn Meniscus Diagnosed in Canada?

Understanding meniscus tear symptoms early is key to getting the right care through Canada’s healthcare system. This article explains what causes a torn meniscus, how doctors diagnose it, and what treatment options are available — from conservative approaches like rest and physiotherapy to surgical repair. If you are experiencing knee pain, swelling, or locking, speak with your family doctor or visit a walk-in clinic for a proper assessment.

Treatment Options for a Torn Meniscus: Benefits and Considerations

Treatment Option	Best Suited For	Benefits	Considerations
Conservative (RICE + Physiotherapy)	Minor or partial tears; stable knees; older adults	No surgery required; low risk; covered under provincial health plans	Recovery may take 4–8 weeks; may not fully heal larger tears
Arthroscopic Meniscus Repair	Young, active patients with tears in the outer (vascular) zone	Preserves meniscus tissue; reduces long-term arthritis risk	Longer recovery (3–6 months); not suitable for all tear types
Partial Meniscectomy	Tears in the inner (avascular) zone; complex or bucket-handle tears	Faster recovery (4–6 weeks); high success rate for pain relief	Removes tissue permanently; may increase arthritis risk over time
Corticosteroid Injections	Patients with significant swelling and inflammation	Quick pain and swelling relief; minimally invasive	Temporary relief only; does not repair the torn meniscus
Platelet-Rich Plasma (PRP) Therapy	Mild to moderate tears; patients seeking non-surgical options	Uses the body’s own healing factors; emerging supportive evidence	Not widely covered by provincial insurance; evidence still developing

Your knee has two C-shaped pieces of rubbery cartilage called menisci (singular: meniscus). One sits on the outer side of the knee (lateral meniscus) and one sits on the inner side (medial meniscus). Together, they act like shock absorbers between the bones of your upper and lower leg.

The meniscus also helps stabilise the knee joint. It spreads your body weight evenly across the joint so no single area takes too much pressure. When the meniscus tears, it can interfere with how your knee moves and feels.

Common Causes of a Torn Meniscus

A torn meniscus usually happens during a twisting movement. This often occurs when your foot is flat on the ground and your knee is slightly bent. For example, pivoting in hockey, squatting to lift something heavy, or making a sudden turn while playing tennis can all cause this injury.

Other knee injuries, such as a torn ligament, can happen at the same time as a meniscus tear. Therefore, it is important to get a full assessment after any significant knee injury.

Age and Wear Over Time

As we age, the meniscus gradually wears down and becomes more fragile. Older adults may tear their meniscus from a minor movement, like getting up from a squat. In contrast, a torn meniscus is quite rare in young children.

Symptoms of a Torn Meniscus

Symptoms can vary widely depending on how severe the tear is. The meniscus itself has no nerve endings. However, pain can come from swelling in the joint and damage to the surrounding tissue.

Mild Tear

A mild torn meniscus may cause only minor pain and light swelling at first. Over the next few days, the knee joint may become more swollen. Walking is usually possible, but pain increases when you squat, lift something heavy, or twist your knee. These symptoms often clear up within two to three weeks.

Moderate Tear

With a moderate tear, you may feel pain along the inner or outer side of the knee, depending on which meniscus is affected. Swelling builds up over two to three days. Bending the knee fully becomes difficult. In addition, twisting movements or squatting can cause sharp pain. Symptoms may ease over time but tend to return with minor twisting or heavy activity.

Severe Tear

A severe tear can cause fragments of the meniscus to shift into the joint space. This leads to what is called a locked knee — the joint cannot straighten fully. Bleeding inside the joint may occur, and swelling appears very quickly after the injury.

Symptoms in Older Adults

Older adults with a worn meniscus may not recall a specific injury. They might notice swelling and mild pain after a simple movement, like rising from a chair. Because the cartilage has weakened over time, even everyday activity can cause a tear.

Pain on the inner side of the knee may point to a medial meniscus tear. Pain on the outer side may suggest a lateral meniscus tear.

How Is a Torn Meniscus Diagnosed?

If your knee pain is severe right after an injury, go to your nearest emergency department or urgent care centre. If the pain is mild, you may wait a few days to see if swelling goes down. However, if symptoms return when you use the knee, see your family doctor or visit a walk-in clinic.

Physical Examination

Your doctor will ask how the injury happened and about any past knee problems. They will examine both knees, checking for swelling, range of motion, and joint stability. X-rays are usually taken to rule out bone damage. Your doctor may then refer you to an orthopaedic specialist for further testing.

According to Mayo Clinic’s overview of torn meniscus, a physical exam combined with imaging is the most reliable way to confirm this injury.

MRI and Arthroscopy

If the diagnosis is unclear, the orthopaedic specialist may order an MRI (magnetic resonance imaging). An MRI gives a detailed picture of the tear’s location and size. It also shows the ligaments, cartilage, and tendons around the knee.

In some cases, the specialist may recommend an arthroscopy. This is a minimally invasive procedure where a thin tube with a camera is inserted through a small cut near the knee. The surgeon can see the tear directly and may repair it during the same procedure. Healthline’s guide to torn meniscus treatment provides a helpful overview of how arthroscopy works.

Treatment Options for a Torn Meniscus

Treatment depends on the type and size of the tear, where it is located, your age, and how active you are. The time since the injury also matters. There are both non-surgical and surgical options available.

Non-Surgical Treatment

Many mild tears heal well without surgery. The standard approach is called the RICE method: Rest, Ice, Compression, and Elevation. Your doctor may also recommend physiotherapy to strengthen the muscles around the knee and restore normal movement.

• Rest: Avoid activities that put stress on the knee.
• Ice: Apply ice wrapped in a cloth for 15 to 20 minutes several times a day.
• Compression: A bandage can help reduce swelling.
• Elevation: Keep the leg raised when sitting or lying down.

Anti-inflammatory medications, such as ibuprofen, can help manage pain and swelling. Always follow the dosage instructions and check with your pharmacist or doctor if you take other medications.

Surgical Treatment

If non-surgical treatment does not work, or if the tear is severe, surgery may be needed. Most surgical repairs are done through arthroscopy. The surgeon may repair the torn tissue directly or remove the damaged portion. There are two main types of surgical procedures:

• Partial meniscectomy: The surgeon removes only the torn piece of the meniscus.
• Total meniscectomy: The entire meniscus is removed. This is less common and generally avoided when possible.

Recovery after surgery varies. Physiotherapy is an important part of getting back to full movement. Most provincial health plans cover medically necessary knee surgery, but wait times can vary. Talk to your orthopaedic specialist about what to expect in your province.

Long-Term Outlook

Without treatment, a torn meniscus can increase the risk of developing osteoarthritis in the knee over time. This is especially true if a large portion of the meniscus is removed. However, with proper treatment and rehabilitation, most people return to their normal activities.

When to See a Doctor

You should see a doctor if your knee is very swollen, you cannot straighten or bend it fully, or you feel like your knee is locking or giving way. These are signs that the injury may be more serious than a minor strain.

Start with your family doctor for a referral to an orthopaedic specialist. If you do not have a family doctor, a walk-in clinic can assess your knee and order imaging if needed. Go to your nearest emergency department if the pain is sudden and severe, or if you heard a popping sound at the time of injury.

Do not ignore ongoing knee pain. Early diagnosis leads to better outcomes and may prevent long-term joint damage.
