Intraarticular observation in the regions where joint spaces are narrow and curved is often difficult. In 1986, an observation method that employs an improved fiberscope inserted intraarticularly was devised for regions where observation with a conventional rigid arthroscope has been difficult. The clinical usefulness of this method was investigated. A total of 45 joints consisting of 11 hip joints, 13 knee joints, and 21 ankle joints were observed by both a rigid arthroscope and a fiberscope, and the findings obtained by the single method and the combined method were compared. The range of visualization was increased by the combined method in 82% of the hip joints, 77% of the knee joints and 62% of the ankle joints, as compared with the single method. Thus the combined method was found to be useful. While the combined method was slightly inferior to the single method of rigid arthroscopy in terms of image resolution, the range of visualization was increased. The combined method is easy to perform and less invasive to the intraarticular structures than the single method, suggesting that the combined method has an important role in intra-articular observation.
在关节间隙狭窄且呈弯曲状的区域进行关节内观察往往很困难。1986年，针对传统刚性关节镜难以观察的区域，设计了一种采用改进型纤维镜关节内插入的观察方法。对该方法的临床实用性进行了研究。使用刚性关节镜和纤维镜对总共45个关节进行了观察，其中包括11个髋关节、13个膝关节和21个踝关节，并比较了单一方法和联合方法所获得的结果。与单一方法相比，联合方法使82%的髋关节、77%的膝关节和62%的踝关节的可视化范围增加。因此发现联合方法是有用的。虽然联合方法在图像分辨率方面略逊于单一的刚性关节镜检查方法，但可视化范围增加了。联合方法操作简便，对关节内结构的侵入性比单一方法小，这表明联合方法在关节内观察中具有重要作用。
