Cartilage
anatomyCartilage is the smooth, rubbery tissue that covers the ends of bones where they meet in a joint, letting them glide over each other with little friction. It has no direct blood supply, so it repairs slowly once worn. Gradual thinning of cartilage is the main change in osteoarthritis, which is why affected joints become painful, stiff and sometimes noisy on movement.
