Torn Meniscus

What is a torn meniscus?

There are 3 bones in the knee. These are the femur, tibia, and patella. The ends of those bones are covered with cartilage. This is a smooth material that cushions the bone and allows the joint to move easily without pain. The cartilage acts as a shock absorber. Between the bones of the knees are 2 crescent-shaped disks of connective tissue, called menisci. These also act as shock absorbers to cushion the lower part of the leg from the weight of the rest of the body.

What causes a torn meniscus?

Meniscus tears can happen during a rotating movement while bearing weight, such as when twisting the upper leg while the foot stays in one place during sports and other activities. Tears can be minor, with the meniscus staying connected to the knee. Or they can be major, with the meniscus barely attached to the knee by a cartilage thread.

What are the symptoms of a torn meniscus?

Each person may have different symptoms. But the most common symptoms are:

Pain, especially when holding the knee straight
Swelling and stiffness
Knee may catch, click, or lock
Knee may feel weak or unstable

These symptoms may look like other health conditions or problems. Always talk with your healthcare provider for a diagnosis.
