本文报道了大鼠膝关节挛缩过程中关节成分的组织学变化。挛缩组关节囊轻度僵硬，可见成纤维细胞样梭形细胞增生，并向关节软骨表面膜样浸润。运动组上述改变轻微。说明ROM Ex不仅能预防肌肉缩短，而且能抑制组织的变化。

Histopathological changes of joint components during contracture in rat knee joint were disclosed. The joint capsule of contracture group were showed slightly stiffness, and hyperplasia of the fibroblast- like spindle- shaped cells wereobserved associated with its infiltration to articular cartilage surface like membrane.
