| Research Abstract |
The diagnostic accuracy of the ultrathin arthroscope was evaluated by examination of the superior joint space of the left temporomandibular joint in 20 sheep. At the time of induction of osteoarthrosis all joints were found to be normal. Six months later the arthroscopic examination was repeated and the results compared to the histologic examination. Similar findings were seen in 11 (55%) joints, with arthroscopic overdiagnosis in 2 (10%) and underdiagnosis in 7 (35%). Eight of 16 (50%) discperforations were found. It was concluded that underdiagnosis occurred because the whole joint space cannot be examined arthroscopically and fibrillated tissue masks bone exposure.
