If you are experiencing unusual knee clicking or your knee locking, it can mean that your meniscus is torn. Your meniscus is a piece of cartilage that cushions and stabilizes the knee joint. While it’s quite a hardy piece of cartilage, a firm twist to the knee can lead to a meniscus tear. Through keyhole surgery, an Arthroscopic Meniscal Debridement will remove any unhealthy or injured tissue from within your knee. This is one of the most common procedures performed in Orthopaedics. If the meniscus is repairable, instead of removing the torn cartilage it may be repaired using special sutures.
