Articular cartilage is the white gristle covering the ends of joint bones ('articulating' bones). It is also called joint cartilage or hyaline cartilage.
It is damage to the articular cartilage which is called 'arthritis' and in the knee all efforts are geared towards preventing any damage or breakdown of this all-essential joint surface, as it has a poor blood supply and does not heal well if damaged.
|The white articular cartilage has a very special internal structure, with the cartilage cells suspended in pockets within a background matrix.||Fibrillar wear of the articular cartilage. The yellowish bone is showing through on the top of the tibia.|
