摘要(Abstract):
目的 观察针刀对中晚期膝骨关节炎兔行为学及膝关节软骨下骨重塑的影响。方法 将30只新西兰兔随机分为空白组、模型组、针刀组、电针组及骨代谢调节剂组,每组6只。采用改良Videman法左后肢伸直位固定制动9周制备模型。空白组与模型组不予干预,其余干预3周。采用改良Lequesne MG评估量表对各组进行行为学评价,应用Micro-CT检测软骨下骨显微结构Tb.Th、Tb.N、Tb.Sp、BVF及BMD。结果 改良Lequesne MG评分模型组较空白组升高(P <0.01),针刀组、电针组较模型组降低(P <0.01),骨代谢调节剂组较模型组无明显改变(P> 0.05)。Micro-CT软骨下骨组织参数定量分析显示,与空白组相比,模型组Tb.Th、Tb.N、BVF及BMD明显升高,Tb.Sp显著下降(P <0.01);与模型组相比,针刀组及电针组Tb.Th、Tb.N、BVF及BMD明显降低,Tb.Sp明显升高(P <0.05或P <0.01)。骨代谢调节剂组无明显改变(P> 0.05)。结论 针刀可通过调整软骨下骨骨组织参数,有效改善异常骨重塑,达到治疗膝骨关节炎的目的。
