To observe the effects of acupotomy intervention on the behavior, morphology and tensile mechanics of knee osteoarthritis (KOA) rabbits, and to explore the biomechanical effects of acupotomy on KOA.
Twenty-four New Zealand male rabbits were randomly divided into four groups: normal group, model group, electroacupuncture group and needle-knife group, with 6 rabbits in each group. In each model group, rabbit KOA model was established by fixing Videman's left hind limb in straight position for 6 weeks. In the electroacupuncture group, rats were treated left on Liang Qiu, Xue Hai, Nei Xi Yan and Wai Xi Yan 3 times a week for 3 weeks. In the acupotomology group, the left quadriceps femoris tendon was released with acupotomology, and the treatment was once a week for 3 weeks. Behavioral tests were performed using Lequesne MG knee joint evaluation method one week after the end of modeling and one week after the end of treatment, and HE staining and mechanical tests were performed one week after the end of treatment.
Behavioral observation before treatment showed that there were significant differences in local pain, gait response, joint activity and joint swelling between the normal group and the model group(
Acupotomy intervention can significantly change the behavior and morphology, significantly improve the mechanical properties of quadriceps femoris tendon stretch, and exert its biomechanical effects to achieve the purpose of treating KOA.
