【目的】观察温针灸联合交叉取穴法治疗膝关节骨性关节炎的临床疗效。 【方法】将50例膝关节骨性关节炎患者随机分为观察组和对照组，每组各25例，对照组给予膝关节局部温针灸治疗，观察组在对照组治疗的基础上，联合肘部交叉取穴治疗。治疗5 d为1个疗程，疗程间隔1 d，共治疗2个疗程。治疗2个疗程后，观察2组患者治疗前后视觉模拟量表 （VAS） 评分、西安大略和麦克马斯特大学骨关节炎指数 （WOMAC） 评分的变化情况。比较2组患者治疗前后步频、步速、步长、步幅、步态周期的变化情况。 【结果】（1） 研究过程中，观察组失访1例，对照组失访4例。最终观察组24例、对照组21例纳入疗效统计。 （2） 治疗后，2组患者的VAS、WOMAC评分均明显下降 （P＜0.01） ，且观察组在改善VAS、WOMAC评分方面明显优于对照组，差异均有统计学意义 （P＜0.05） 。 （3） 治疗后，2组患者的步频与步速均较治疗前明显改善，且差异有统计学意义（P＜0.05） ，步长与步幅参数较治疗前稍有改善，但差异无统计学意义 （P＞0.05） 。治疗后，观察组在改善患者步频、步长、步速、步幅方面稍优于对照组，但差异无统计学意义 （P＞0.05） 。 （4） 治疗后，2组患者的步态周期均明显改善 （P＜0.05） ，观察组在改善步态周期方面稍优于对照组，但差异无统计学意义 （P＞0.05） 。 【结论】温针灸联合交叉取穴法治疗膝关节骨性关节炎的疗效确切，具有良好的镇痛效果，可明显改善患者日常关节的功能情况，并提高膝关节骨性关节炎患者的步频、步速，缩短步态周期，从而提高患者生活质量，疗效显著。

Objective To observe the clinical efficacy of warming-needle moxibustion combined with cross acupoint selection method in the treatment of knee osteoarthritis （KOA） . Methods Fifty patients with KOA were randomly divided into observation group and control group，25 patients in each group. The control group was treated with warming-needle moxibustion on local of the knee joint，and the observation group was treated with elbow cross acupoint selection on the basis of the treatment of the control group. The course of treatment covered five days，with an interval of one day between courses of treatment，and a total of two courses of treatment. After two courses of treatment，the changes in Visual Analogue Scale （VAS） scores and Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） scores in the two groups before and after treatment were observed. Changes in step frequency，step speed，step length，stride，and gait period between the two groups of patients before and after treatment were compared. Results （1） During the research，there was one case in the observation group and four cases in the control group lost to follow-up . Finally，24 cases in the observation group and 21 cases in the control group were included in the efficacy statistics. （2） After treatment，the scores of VAS and WOMAC of patients in the two groups decreased significantly（P＜0.01），and the improvement in the observation group was significantly superior to that in the control group，and the differences were statistically significant（P＜0.05） . （3） After treatment，the step frequency and step speed of patients in the two groups were significantly improved compared with those before treatment， and the difference was statistically significant（P＜0.05）， and the parameters of step length and stride were slightly improved compared with those before treatment， but the difference was not statistically significant （P＞0.05） . After treatment，the observation group was slightly superior to that in the control group in improving the patients’ step frequency，step length，step speed and stride，but the difference was not statistically significant （P＞0.05） . （4） After treatment，the gait period of patients in both groups were improved significantly（P＜0.05），and the improvement in the observation group was significantly superior to that in the control group，but the difference was not statistically significant （P＞0.05） . Conclusion The efficacy of warming-needle moxibustion combined with cross acupoint selection method in the treatment of KOA is precise，with good analgesic effect，moreover，it can significantly improve the daily joint function of the patients，and improve the step frequency and step speed of patients with KOA and shorten the gait period，so as to improve the quality of life of patients，with remarkable therapeutic effect.
