[Establishment of an animal model of osteochondral defect by arthroscope in TMJ].

OBJECTIVE
To create an animal model of osteochondral defect in temporomandibular joint (TMJ) by arthroscope to minimize the surgical injury.


METHODS
Subchondral drilling on the anterior slope of condyle and posterior slope of eminence were performed on 12 rhesus monkeys (24 joints) by arthroscope.


RESULTS
The osteochondral defect models of TMJ were successfully made on 12 monkeys (24 joints).


CONCLUSION
There are fewer injuries and bias in the animal models of TMJ osteochondral defect by arthroscope than by open surgery.
