Meniscus Tear


A meniscus tear is a common knee injury that can happen to anyone, but it’s more common in athletes and older adults. The meniscus is a rubbery, C-shaped disc that cushions your knee and helps distribute weight and absorb shock. A meniscus tear occurs when the meniscus is torn or damaged, causing pain, swelling, and limited mobility.

There are several causes of meniscus tears, including direct impact, twisting or rotating your knee while bearing weight, and degenerative changes due to aging. The severity of a meniscus tear can range from minor to severe, and the treatment options vary based on the extent of the injury.

Understanding Meniscus Tears

The meniscus is a C-shaped piece of cartilage located in the knee joint. It acts as a shock absorber and helps to distribute weight evenly across the joint. A meniscus tear occurs when this cartilage is damaged or torn due to sudden twisting or turning of the knee, or from impact during physical activities such as sports.

There are two types of meniscus tears: traumatic and degenerative. Traumatic tears often occur due to sudden movements or impact, while degenerative tears develop over time due to wear and tear on the knee joint. The severity of a meniscus tear is classified as either minor, moderate, or severe, depending on the size and location of the tear.

Minor tears may heal on their own with rest and conservative treatments, while moderate to severe tears may require medical intervention. Understanding the type and severity of a meniscus tear is important for determining the most appropriate course of treatment.

Signs and Symptoms of a Meniscus Tear

A meniscus tear can cause various signs and symptoms, depending on the extent and location of the injury. Some of the common indications of a meniscus tear include:

  • Pain in the knee joint, particularly along the joint line
  • Swelling in the affected knee
  • Stiffness and difficulty moving the knee
  • Clicking or popping sounds in the knee
  • Weakness or buckling of the knee
  • Difficulty fully extending or bending the knee

It’s essential to note that not all meniscus tears present with significant symptoms. Sometimes, a small tear may not cause noticeable discomfort or require medical intervention. However, more extensive tears can lead to persistent pain and joint dysfunction that can interfere with daily activities.

Diagnosing a Meniscus Tear

Diagnosing a meniscus tear typically involves a combination of physical examination and imaging tests. Your healthcare provider will first ask about your symptoms and medical history, then physically examine the affected knee. This may include tests to evaluate the joint’s range of motion, stability, and tenderness.

If a tear is suspected, imaging tests such as x-rays or magnetic resonance imaging (MRI) may be performed to confirm the diagnosis. An MRI is usually the preferred imaging test as it can provide detailed images of the soft tissue structures in the knee, including the meniscus.


Sometimes, your healthcare provider may recommend an arthroscopy to diagnose a meniscus tear. This minimally invasive surgical procedure involves inserting a small camera (arthroscope) into the knee joint to visualise the area. This allows the healthcare provider to confirm the diagnosis and evaluate the extent of the injury more accurately.

It is essential to seek medical attention if you suspect a meniscus issue, as early diagnosis and treatment can improve outcomes and prevent further damage to the knee joint.

Non-Surgical Treatment Options for Meniscus Tears

When it comes to treating meniscus tears, surgery is not always necessary. Non-surgical treatment options are available to help manage symptoms and promote healing.


Rest is crucial in the early stages of a meniscus tear. It is recommended to limit activities that aggravate the injury and to avoid putting weight on the affected knee as much as possible. Crutches may be necessary to assist with mobility.

Cold Therapy

Cold therapy is an effective way to reduce pain and swelling. Applying an ice pack to the affected knee for 15 to 20 minutes at a time, several times a day, can help alleviate symptoms.

Compression and Elevation

Compression and elevation can also help reduce swelling and promote healing. Wearing a compression bandage or sleeve on the affected knee and keeping it elevated above heart level can aid in recovery.

Physical Therapy

Physical therapy exercises can help improve strength and flexibility in the affected knee. Specific exercises may include quad sets, straight-leg raises, and hamstring curls.


Rehabilitation is an important part of non-surgical treatment for meniscus tears. It may involve a combination of rest, cold therapy, compression and elevation, physical therapy exercises, and supportive devices such as knee braces.

By following these non-surgical treatment options, meniscus tears can often heal on their own. However, it is important to consult with a healthcare professional to determine the best course of action based on the severity of the injury.

If non-surgical treatments are unsuccessful, surgical intervention may be necessary. Surgery is typically recommended for larger or complex tears that cause significant knee instability or for those experiencing persistent knee pain and limited mobility.

Arthroscopic Meniscus Repair

Arthroscopy is a minimally invasive surgical method that is commonly used to repair a torn meniscus. During this procedure, a small camera is inserted into the knee joint, allowing the surgeon to see and assess the tear.

They will then use specialised instruments to repair the tear by sewing the torn edges together. This type of surgery is typically recommended for younger patients with acute tears in the outer portion of the meniscus.

Partial Meniscectomy

Partial meniscectomy involves the removal of the torn portion of the meniscus. This type of surgery is more commonly recommended for older patients or those with complex tears that cannot be repaired.

This surgery aims to remove the damaged portion of the meniscus while preserving as much healthy tissue as possible, to maintain joint stability and reduce the risk of future complications.

Risks and Recovery

As with any surgery, there are risks associated with a meniscus tear repair. These can include infection, blood clots, and nerve damage.

Recovery time will vary depending on the type of surgery and the patient’s overall health but typically involves rest, physical therapy, and rehabilitation exercises to restore strength and mobility to the knee joint.

Recovery and Rehabilitation after Meniscus Tear Surgery

Recovering from meniscus tear surgery can be lengthy, but the right rehabilitation plan can help you get back to normal activities sooner. Here’s what you need to know:

Post-Operative Care

After surgery, you will likely need to use crutches for some time to keep weight off the affected knee. Your doctor will also prescribe pain medication to help manage discomfort during the initial recovery period. Following all post-operative instructions carefully is essential to ensure the best possible outcome.

Physical Therapy Exercises

Physical therapy is a crucial component of meniscus tear surgery recovery. Your physiotherapist will create a tailored rehabilitation plan to help you regain strength, increase your range of motion, and reduce pain. This may include exercises such as straight leg raises, hamstring curls and calf raises. Gradually increasing the intensity and frequency of these exercises will help you recover more quickly.

Expected Timelines

Recovery times can vary, but most people can resume light activities within a few weeks of surgery. It may take several months to regain full strength and mobility, and some activities may need to be avoided for an extended period. Your physiotherapist will discuss your expected timeline for recovery and help you set realistic goals.

Managing Expectations

It’s important to remember that everyone’s recovery experience is different. Some people may have a faster or slower recovery time, depending on factors such as age, overall health, and the severity of the injury.

It’s essential to communicate openly with your doctor and physiotherapist and to ask questions about any concerns or expectations you may have.

  • Follow all post-operative instructions carefully, including medication, crutch use, and rest.
  • Attend physical therapy sessions regularly and complete prescribed exercises on your own.
  • Be patient with the recovery process, and don’t push yourself too hard too soon.
  • Communicate openly with your healthcare team about any concerns or questions.

Preventing Meniscus Tears and Conclusion
