The menisci are C-shaped pieces of tough cartilage that rest on either side of the knee, which help to distribute body weight across the knee. A meniscus tear is common after a traumatic injury, and most frequently occurs when the knee joint is bent and the knee is then twisted.
A torn meniscus causes pain and swelling, and may also be accompanied by a frequently locking joint and the inability to completely straighten the knee. Some people experience a popping or clicking sensation within the knee as well.
Treatment for a meniscus tear often begins with conservative methods such as rest, ice or over-the-counter medication. If these treatments are not effective and symptoms continue, you may benefit from meniscus repair surgery. Meniscus repair is an arthroscopic procedure in which the torn segment of the meniscus is removed and the torn edges are sutured together, which allows them to heal properly.
