MENISCUS TEARS
The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between the shinbone and the thighbone. It can be torn if you suddenly twist your knee while bearing weight on it. A torn meniscus is one of the most common knee injuries
If your child needs surgery or casting, our Fracture Care Clinic opens every day and you do not need an appointment. Surgery rooms get scheduled every morning, so your child receives the care and attention they need right away.
Meniscus Tears
A torn meniscus is a common injury to the knee that can cause pain, swelling, and difficulty with movement. The meniscus is a C-shaped piece of cartilage in the knee joint. It acts as a cushion between the thighbone and the shinbone. A tear in this cartilage can occur due to a sudden twist or turn of the knee. It can also result from wear and tear over time.
Types of Meniscus Tears
The meniscus is a C-shaped cartilage that provides a cushioning effect between the thigh bone and shin bone in the knee joint. It also stabilizes the knee joint and helps in shock absorption. However, due to various factors, the meniscus can tear, which can result in pain, swelling, and limited mobility. There are three types of meniscus tears, which include:
- Radial Tear: A radial tear runs perpendicular to the meniscus’s fibers. It can occur at any location along the meniscus and can vary in size and shape. Radial tears are often caused by trauma to the knee, such as sudden twisting or turning. This type of tear can also occur due to degeneration or wear and tear on the meniscus over time. Radial tears may cause locking or catching sensations in the knee joint, as well as pain and swelling.
- Horizontal Tear: A horizontal tear runs parallel to the joint surface. This type of tear can occur in the middle or outer edge of the meniscus, but it is less common than a radial tear. Horizontal tears can be caused by repetitive stress or wear and tear on the meniscus over time. They can also occur due to a sudden injury, such as a fall or direct blow to the knee. Horizontal tears can cause pain, swelling, and limited mobility in the knee joint.
- Flap Tear: A flap tear occurs when a portion of the meniscus becomes detached and flips over. This type of tear can be caused by trauma to the knee or degeneration of the meniscus over time. Flap tears can cause locking or catching sensations in the knee joint, as well as pain and swelling.
Identification of a Torn Meniscus
During a physical examination, the doctor will assess the knee joint’s range of motion. Then the doctor will check for any swelling, and apply pressure to different parts of the joint. That will identify areas of pain and tenderness. The doctor may also perform special tests, such as the McMurray test or Apley’s compression test. Those tests will further evaluate the knee joint’s stability and identify specific types of meniscus tears.
Imaging tests, such as an MRI (magnetic resonance imaging) or X-ray, can provide detailed images of the knee joint. These tests help the doctor identify the location and type of meniscus tear. An MRI is the most accurate imaging test for identifying meniscus tears. This is because it can provide high-resolution images of soft tissue structures, such as the meniscus.
In some cases, the doctor may perform an arthroscopy, which is a minimally invasive surgical procedure. This allows the doctor to visualize the inside of the knee joint and repair the meniscus tear directly. During an arthroscopy, the doctor can identify the type of meniscus tear and repair it using specialized surgical tools.
Overall, a combination of physical examination and imaging tests is typically used to diagnose and identify the type of meniscus tear accurately.
QUESTIONS AND ANSWERS
How did my child get a meniscus tear, and what are the common causes?
A meniscus tear in a child can result from a variety of causes, often related to sports or physical activities. Common causes include:
- Sports Injuries: Meniscus tears frequently occur during sports that involve sudden stops, twists, or changes in direction, such as soccer, basketball, or gymnastics.
- Trauma: Direct impact to the knee, such as a fall or collision, can lead to a meniscus tear.
- Degenerative Changes: In some cases, especially in older children or adolescents, wear and tear on the meniscus over time can contribute to tears.
How is a meniscus tear diagnosed, and what tests are needed?
Diagnosis of a meniscus tear typically involves a combination of a physical examination and imaging studies. The healthcare provider will assess the child’s symptoms, examine the knee for swelling, tenderness, and range of motion, and inquire about the circumstances of the injury.
Imaging tests, such as MRI (Magnetic Resonance Imaging), are commonly used to visualize the meniscus and confirm the diagnosis. While X-rays may be performed to rule out other potential injuries, they are not as effective at detecting soft tissue injuries like meniscus tears.
What is the treatment plan for my child's meniscus tear, and what is the expected recovery time?
The treatment approach for a meniscus tear in a child depends on factors such as the size and location of the tear, the child’s age, and activity level. Common treatment options include:
- Rest and Activity Modification: Initially, the child may need to avoid activities that could worsen the tear.
- Physical Therapy: Physical therapy exercises can help strengthen the muscles around the knee, improve flexibility, and enhance stability.
- Bracing and Supportive Measures: In some cases, a knee brace may be recommended to provide additional support.
- Surgical Intervention: For more significant tears or cases where conservative measures are not effective, arthroscopic surgery may be considered to repair or remove the torn portion of the meniscus.
Parents should maintain open communication with the healthcare team to address any concerns and monitor the child’s progress throughout the recovery process.

Symptoms
The symptoms of a torn meniscus can vary depending on the severity and location of the tear. However, common symptoms of a torn meniscus may include:
- Pain in the knee joint, particularly when bearing weight or moving the knee
- Swelling or stiffness in the knee joint
- Difficulty straightening or bending the knee
- A popping or clicking sensation when moving the knee
- Feeling like the knee is giving way or locking up
- Limited range of motion in the knee joint
- Instability or weakness in the knee joint
- Difficulty walking or standing for extended periods of time
- Pain or discomfort when touching the knee joint
- Development of osteoarthritis in the affected knee joint over time.
It is important to note that not all meniscus tears produce symptoms. Some people may experience only mild or intermittent symptoms. However, if your child experiences any of the above symptoms, it is important to consult with a healthcare professional for proper diagnosis and treatment of the knee injury.
Torn Meniscus Treatment
Treatment for a torn meniscus can vary depending on the severity of the tear and the patient’s overall health. In some cases, the tear may heal on its own with rest, ice, and physical therapy. Non-surgical treatments for a torn meniscus can include:
- Rest and ice: Resting the knee and applying ice can help reduce swelling and relieve pain.
- Physical therapy: Exercises can help improve strength, flexibility, and range of motion in the knee joint.
- Pain medication: Over-the-counter pain medications can help relieve pain and reduce inflammation.
In cases where the tear is more severe or does not heal on its own, surgery may be necessary. Surgical treatment for a torn meniscus can include:
- Meniscus repair: In this procedure, the torn portion of the meniscus is reattached to the surrounding tissue using sutures or anchors.
- Partial meniscectomy: This involves removing the torn portion of the meniscus while leaving the remaining tissue intact.
- Total meniscectomy: In rare cases, the entire meniscus may need to be removed, although this can lead to long-term complications such as arthritis.
Prevention Measures
While some meniscus tears occur due to sudden injury or trauma, others can be prevented by taking certain precautions. Here are some prevention measures that can help reduce the risk of meniscus tears:
- Strengthen the muscles around the knee: Strong muscles can help support the knee joint and reduce the risk of injury. Focus on exercises that target the quadriceps, hamstrings, and calf muscles.
- Maintain a healthy weight: Excess body weight can put added stress on the knee joint, increasing the risk of injury. Maintaining a healthy weight can help reduce this risk.
- Wear proper footwear: Wearing shoes that provide good support and cushioning can help reduce the impact on the knee joint during physical activity.
- Warming-up and stretching before physical activity: Warming-up and stretching can help prepare the muscles and joints for physical activity, reducing the risk of injury.
- Use proper technique during physical activity: Using proper technique during physical activity, such as running and jumping, can help reduce the risk of injury to the knee joint.
- Avoid activities that put excessive stress on the knee joint: High-impact activities, such as running and jumping, can put excessive stress on the knee joint, increasing the risk of injury. Consider low-impact activities, such as swimming or cycling, as an alternative.
- Take breaks and rest when necessary: Resting and taking breaks during physical activity can help reduce the risk of overuse injuries, including meniscus tears.
In summary, taking preventive measures such as strengthening muscles, maintaining a healthy weight, wearing proper footwear, warming up, using proper technique, avoiding high-impact activities, and taking breaks can help reduce the risk of meniscus tears.
Recovery Time
Recovery time for a torn meniscus can vary depending on the severity of the tear and the type of treatment used. Non-surgical treatments may require several weeks of rest and physical therapy, while surgical treatments may require several months of recovery and rehabilitation. It is important to follow the doctor’s recommendations for recovery and rehabilitation in order to achieve the best possible outcome and avoid future injury to the knee joint.
Summary
In summary, a torn meniscus is a common injury to the knee that can cause pain, swelling, and difficulty with movement. There are several types of meniscus tears, and diagnosis is typically made through a physical exam and imaging tests. Treatment can include non-surgical options such as rest, ice, and physical therapy, as well as surgical options such as meniscus repair or partial meniscectomy. Prevention measures can help reduce the risk of a torn meniscus, and recovery time can vary depending on the type and severity of the tear and the treatment used.
As previously mentioned, our doctors at the Medical City Children’s Orthopedics and Spine Specialists, with offices in Arlington, Dallas, Flower Mound, Frisco, and McKinney, TX, will recommend physical therapy as the torn meniscus starts to heal. That will support the muscles and ligaments in becoming stronger. After that, your child ought to be able to resume his or her favorite activities in roughly nine months. For athletes, it may take up to a year before they may resume their sport.
