摘　　要：针刀干预对髌韧带生物力学特性可以产生一定的影响,故针刀对膝骨关节炎具有一定的治疗作用.本研究采用左后肢伸直位固定制动法造成膝骨关节炎模型兔(Leporidae),并应用针刀进行治疗,治疗结束后,通过对膝关节髌韧带进行应力松弛、蠕变及拉伸等力学测试,研究针刀干预对髌韧带生物力学的影响.结果显示,针刀干预可以明显改善髌韧带的生物力学特性,激发髌韧带的拉伸、蠕变、应力松弛特性的恢复,维护膝关节的平衡与稳定.Acupotomy intervention can impact the biomechanical characteristics of patellar ligament, so it has some effect on knee osteoarthritis. We induced the KOA model by fixing the left legs of the model rabbits and treated them with the method of acupotomy intervention. After the treatment, we tested the tension, creep and stress relaxation data of patellar ligament to study the effect of acupotomy on the biomechanical characteristics of patellar ligament. The results showed that acupotomy intervention can significantly improve the biomechanical properties of patellar ligament, stimulate the recovery of tension, creep, and stress relaxation, and maintain balance and stability of the knee joint.
