The suggestion that the blood supply to subchondral bone plays an active role in the nutrition of adult articular cartilage is a source of controversy. Morphological confirmation of the presence of subchondral defects extending through the basal cartilage layer of the adult human talus is presented. Perfusion of a fluorescent dye through these breaks offers the possibility that they may serve as active pathways for the transport of nutrients to the cartilage. The distribution patterns of the… CONTINUE READING
