Cartilage damage may include softening of the shiny white gristle covering the ends of a joint or it may progress to total destruction and leave the end of the bone bare.
Early softening of the joint cartilage of the femur - see the dimpling by the probe - is called chondromalacia.
Fibrillar wear of the articular cartilage. The yellowish bone is showing through on the top of the tibia.
Nomenclature
This is not the same as meniscus damage - people sometimes get confused because sportspeople talk of their 'cartilages' when actually they mean 'meniscus'.
