目的：评价经筋针刺法和常规针刺法治疗膝骨关节炎的临床疗效。方法：计算机检索中国知网、万方、维普、Cochrane临床对照试验中心注册库及PubMed数据库，收集建库至2019年4月25日发表的有关经筋针刺法治疗膝骨关节炎的随机对照试验（RCT），将收集到的文献进行筛选，并由两名评价者独立提取资料和评价文献质量后采用RevMan 5.3软件进行Meta分析。结果：共纳入31个随机对照试验，涉及2321例患者。Meta分析结果显示：经筋针刺法总有效率优于常规针刺法,其合并的有效率RR值及95%CI为RR=1.21，95%CI（1.16，1.25）。WOMAC疼痛、僵硬、日常生活难度评分均优于常规针刺法，其各项评分的SMD值及95%CI分别为：SMD=-2.03,95%CI[-2.37,-1.70]；SMD=-0.20,95%CI[-0.42,-0.02]；SMD=-0.70，95%CI[-0.96, -0.44]。结论：因为经筋针刺法减张效果强于常规针刺，能迅速缓解疼痛和运动功能障碍，所以经筋针刺法对KOA疗效优于常规针刺法。
Objective: To evaluate the clinical efficacy of muscular region’s acupuncture and conventional acupuncture in the treatment of knee osteoarthritis, and to explore the effects of different needles and needling methods on the efficacy of knee osteoarthritis. Methods: CNKI, Wanfang, Weipu, Cochrane Clinical Controlled Trial Center and PubMed database were searched by computer. Randomized controlled trials (RCTs) on muscular region’s acupuncture for knee osteoarthritis which published until April 25, 2019 were collected and selected. The collected literature was screened and independently evaluated by two evaluators. RevMan 5.3 software was used for meta-analysis after extracting data and evaluating the quality of literature. Results:A total of 31 randomized controlled trials were included ,with 2321 cases. Meta-analysis results showed that the effective rate of the muscular region’s acupuncture are superior to that of the conventional acupuncture method. RR and 95% CI values of effective rate were RR=1.21 and 95% CI [1.16，1.25].WOMAC scores of pain, stiffness and difficulty in daily life were better than those of conventional acupuncture. The SMD values and 95% CI of each score were SMD=-2.03 and 95% CI[-2.37,-1.70], SMD=-0.20 and 95%CI[-0.42,-0.02] , SMD=-0.70 and 95%CI[-0.96,-0.44]. Conclusion: Because the effect of reducing tension of muscular region’s acupuncture is better than that of conventional acupuncture, which can quickly relieve pain and motor dysfunction, the effect of muscular region’s acupuncture on KOA is better than that of conventional acupuncture.
