The lateral meniscus is one of two C-shaped pieces of cartilage that act as cushions between the thighbone (femur) and shinbone (tibia) in the knee joint. It helps to distribute weight evenly across the joint and prevent the bones from rubbing against each other. A lateral meniscus tear is a tear in the cartilage of the lateral meniscus.

Symptoms of a Lateral Meniscus Tear

The symptoms of a lateral meniscus tear can vary depending on the severity of the tear. Some common symptoms include:

• Pain in the knee, especially when bending or twisting the knee

• Swelling in the knee

• Locking or catching of the knee

• Giving way of the knee

• Difficulty walking or running

Causes of a Lateral Meniscus Tear

Lateral meniscus tears can be caused by a sudden twisting or pivoting motion of the knee, such as might occur during sports or other activities. They can also be caused by a direct blow to the knee.

Treatment for a Lateral Meniscus Tear

The treatment for a lateral meniscus tear depends on the severity of the tear. In some cases, conservative treatment, such as rest, ice, compression, and elevation (RICE), may be enough to relieve symptoms. However, if conservative treatment does not work, surgery may be necessary.

Surgery for Lateral Meniscus Tear

There are two main types of surgery for lateral meniscus tear:

• Meniscus repair: This is the preferred treatment for tears that can be repaired. The surgeon stitches the torn edges of the meniscus back together.

• Meniscus removal: This is a less common treatment option for tears that cannot be repaired. The surgeon removes the torn piece of meniscus.

Recovery from Lateral Meniscus Repair

Recovery from lateral meniscus repair takes a few months. During the first few weeks after surgery, you will need to use crutches to avoid putting weight on your knee. You will also need to attend physical therapy to help you regain range of motion and strength in your knee.

Outlook for Lateral Meniscus Repair

The outlook for lateral meniscus repair is generally good. Most people are able to return to their normal activities within 3-4 months after surgery. However, it is important to follow our instructions carefully during your recovery to minimize the risk of complications.
