To study the effects of immobilization upon the ultrastructure and surface contour of articular cartilage, the knee joints of adult dogs were immobilized with the Ilizarov apparatus for different lengths of time. Following immobilization, half of the dogs were permitted unrestrained joint motion, also for different lengths of time. Using light transmission and scanning electron microscopy it was observed that the degree of degenerative and destructive cartilage changes increased with greater immobilization. With the re-mobilization group, it was learned that the longer the period of mobilization following immobilization, the greater the reparative processes.
为研究固定对关节软骨超微结构和表面轮廓的影响，用伊里扎洛夫器械对成年犬膝关节进行不同时长的固定。固定后，让半数犬进行不同时长的无限制关节活动。通过光镜透射和扫描电子显微镜观察发现，固定时间越长，软骨退变和破坏程度越高。对于再活动组，发现固定后活动时间越长，修复过程越显著。
