Arthroscopic meniscectomy

The menisci are two small cartilage cushions between the thigh bone (femur) and the shin bone (tibia). They absorb shocks and help stabilise the knee. A twisting injury, a sporting effort or simple wear with age can tear them. The torn fragment then causes pain, swelling and sometimes locking of the knee. A meniscectomy removes only the torn part of the meniscus, preserving as much healthy tissue as possible. It is performed by arthroscopy: a small camera and fine instruments are inserted into the knee through two incisions a few millimetres long. When the tear is suitable, particularly in younger patients, the surgeon may choose to repair (suture) the meniscus rather than remove part of it. Surgery is offered when pain persists despite rest, medication and physiotherapy, or straight away if the knee is locked. In older people whose meniscus is worn by arthritis, surgery is not automatic: medical treatment is usually tried first. At Clinique Pasteur Tunis, meniscectomy is performed in the operating theatre with an arthroscopy unit, most often as a day case. Your orthopaedic surgeon explains beforehand what will be done and plans your rehabilitation with you.
