Knee cartilage injuries
There are two types of cartilage within the knee, the surface or chondral cartilage and the meniscus. Either can be damaged due to injury or degenerative change. Once damaged, they often don’t heal due to relatively poor blood supply. Symptoms may include catching or lock from the knee which can be painful. There may also be swelling and kneecap instability and sometimes clicking. In a small proportion of cases, symptoms can settle following rest, but may return once activity is resumed. If symptoms don’t settle then a knee arthroscopy should be considered. In some cases, the cartilage tear can be repaired but mostly it is removed to alleviate symptoms.
