[An experimental study on arthroscopic chondrocytes transplantation for repair of osteochondral defects in TMJ].
OBJECTIVE
To certify the feasibility of arthroscopic chondrocytes transplantation in temporomandibular joint (TMJ) and the nature of repaired tissue with autologous chondrocytes transplantation in osteochondral defects.


METHODS
The animal models of osteochondral defects in TMJ were established in 12 rhesus monkeys. Autologous auricular chondrocytes were transplanted to the defects by arthroscope. Healing of the defects was assessed by gross examination, light microscope, immunohistochemical staining.


RESULTS
The repaired tissues with chondrocytes transplantation were fibrocartilages.


CONCLUSIONS
The technique of arthroscopic chondrocytes transplantation is feasible and the nature of repaired tissue is closest to the normal cartilage, compared with those of subchondral drilling and cartilage transplantation.
