The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.
