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 with the histologic examination. Similar findings were seen in 11 joints (55%), with arthroscopic overdiagnosis in two (10%) and underdiagnosis in seven (35%). Eight of 16 (50%) disc perforations were found. It was concluded that underdiagnosis occurred because the whole joint space cannot be examined arthroscopically and fibrillated tissue masks bone exposure.
通过对20只绵羊的左颞下颌关节上关节间隙进行检查，评估了超薄关节镜的诊断准确性。在诱发骨关节炎时，发现所有关节均正常。六个月后重复进行关节镜检查，并将结果与组织学检查进行比较。在11个关节（55%）中发现了相似的结果，其中2个关节（10%）存在关节镜过度诊断，7个关节（35%）存在诊断不足。在16个（50%）盘状穿孔中发现了8个。得出的结论是，之所以会出现诊断不足，是因为无法通过关节镜检查整个关节间隙，且纤维化组织掩盖了骨质暴露。
