What is a meniscus tear?
The knee is the largest joint in the human body, allowing flexion, extension and twisting movements. Since the knee has many components, such as tendons, ligaments, cartilage, and bones, it is susceptible to a wide number of injuries. One of the more commonly injured structures of the knee is the meniscus. The menisci are fibrocartilage structures, different from the cartilage on the end of your bones, that act as shock absorbers for the knee joint and distribute the weight load of your body throughout your knee. Occasionally with a twisting or deep bending motion, you can injure or tear a meniscus, especially during sports. The meniscus can tear in isolation or along with other structures such as the central or side ligaments of the knee. The menisci look roughly like the letter “C” within the knee joint. There are two menisci in each knee, one on the medial side and the other on the lateral side. When the meniscus tears, the shape of the tear will determine how the tear should be treated. Dr. Alexander Brown, orthopedic knee specialist, can diagnose and treat patients in Nashville, Tennessee and the surrounding areas who have a meniscus tear injury.
