Meniscus tears are caused by an injury or trauma to the knee, or from degenerative conditions such as osteoarthritis. Since most of the meniscus has no blood supply, these tears are difficult to heal and may worsen over time.
The most common symptom of a meniscus tear is the pain in the knee. Other symptoms may include swelling, tenderness when pressing on the sides of the knee joint, a popping or clicking sound or sensation when moving the knee, or limited mobility.
Treatment options for meniscus tears include rest, cold compress, physical therapy, anti-inflammatory medications and immobilization of the knee in a brace or cast. Severe cases may require torn meniscus surgery.
