Cartilage is the tough, flexible tissue that covers the surface of the joints, including the hip. It cushions the joints, acting as a shock absorber, and helps the bones to slide smoothly over one another for ease of movement. Injuries to the cartilage are common and can be the result of gradual wear and tear, as in the case of osteoarthritis, or sudden trauma, such as with a sporting injury.
Hip cartilage injuries sometimes get better by themselves, however more severe damage may require surgery. Because cartilage has no blood supply of its own, cartilage injuries can take much longer to heal than other types of tissue injury.
