Cartilage, or chondral, damage is known as a lesion and can range from a soft spot on the cartilage (Grade I lesion) or a small tear in the top layer to an extensive tear that extends all the way to the bone (Grade IV or full-thickness lesion).
The most common location for cartilage damage is in the knee joint. In some cases of knee joint damage, bleeding can occur inside the knee joint, which is known as haemarthrosis. There may also be swelling and dark red blotches on the skin that are similar to bruises.
