A torn cartilage is a common knee injury in sport. As the knee joint bends the thigh bone moves on the top surface of the shin bone. Under certain circumstances, the meniscus (often referred to as cartilage) that provides a 'cushion' between the two bones can get nipped and torn.
In some cases, after the initial knee pain and swelling, the swollen knee joint settles down and normal activities can be resumed without knee surgery. However, in the case of a sporting individual, if the flap of torn cartilage causes knee locking or giving way, surgery is required. Knee surgery is usually done using arthroscopy, with as little meniscus tissue as possible removed, to minimise the risk of arthritis of the knee.
