To examine the effects of direct electric current on ligament healing in rabbits, a full-thickness defect of the patellar ligament was electrically stimulated for time periods of up to seven weeks. The rabbits were randomly assigned to biomechanical and biochemical studies, and healing was evaluated by these parameters. Electrical stimulation was shown to restore tensile stiffness in a short period of time and to decrease the relative proportion of Type III collagen more rapidly than in the control group. However, electrical stimulation did not change the collagen content of newly formed tissue. Electricity enhances the repair process of the ligament by changing the ratio of collagen types.
为研究直流电对兔韧带愈合的影响，对髌韧带全层缺损进行长达7周的电刺激。将兔随机分组进行生物力学和生化研究，并通过这些参数评估愈合情况。结果显示，电刺激可在短时间内恢复拉伸刚度，并比对照组更快地降低III型胶原蛋白的相对比例。然而，电刺激并未改变新形成组织的胶原蛋白含量。电通过改变胶原蛋白类型的比例来促进韧带的修复过程。
