     【摘要】 目的 观察关节负荷和运动对关节软骨缺损修复的影响。方法 用成年犬10只,分别在双侧股骨髁部造成面积相同的全层软骨缺损,实验侧安装关节撑开运动器。术后20~24周显露关节,大体观察软骨修复情况,并取材做组织学和电镜观察。结果 实验侧软骨修复明显优于对照侧,实验侧以透明和纤维软骨为主,对照侧以纤维组织为主。结论 关节撑开和运动能促进关节软骨的修复。

    【Abstract】 Objective To observe the effect of repairing on the articular cartilage defects under the joint load and motion.Methods Full-thickness cartilage defects with the same area were created on both of the articular surface of the femoral condylus in10adult dogs.The test side were installed articular distraction/motion device.The articular surˉface were exposed at20~24weeks postoperation and observed the results by histology and ECM.Results The results of carticular repairing in test group were significant than that of control group.Conclusion The method of the joint distracˉtion/motion can promote the repairing of the articular cartilage. ......
