超声引导下射频针刀治疗早中期膝关节骨关节炎的临床研究

Clinical efficacy of ultrasound-guided radiofrequency acupotomy therapy in treatment of early and middle-stage knee osteoarthritis

目的:研究超声引导下射频针刀干预早中期膝关节骨关节炎(KOA)的临床效应作用。方法:本研究纳入有效病例共62例,随机分为射频针刀治疗组和常规针刀对照组,两组均在超声引导下进行操作,每周1次,共治疗2次,分别在治疗前、治疗后、治疗结束后2周和治疗结束后1个月进行西安大略和麦克马斯特大学骨关节炎指数(WOMAC)评分进行临床疗效的评价。结果:治疗前两组的性别、年龄、BMI指数、WOMAC疼痛评分、WOMAC僵硬评分、WOMAC功能评分、WOMAC总评分间的差异均无统计学意义(均P>0.05)。治疗后、治疗结束后2周和治疗结束后1个月,两组患者的WOMAC疼痛评分、WOMAC僵硬评分、WOMAC功能评分、WOMAC总评分均显著低于本组治疗前,其差异有统计学意义(P<0.01)。治疗组在治疗后、治疗结束后2周和治疗结束后1个月的WOMAC疼痛评分、WOMAC僵硬评分、WOMAC功能评分、WOMAC总评分均小于同期对照组,其差异均有统计学意义(均P<0.05)。结论:超声引导下射频针刀治疗早中期KOA临床疗效确切,能有效减轻患者的疼痛,从而改善膝关节功能。

Objective To study the clinical efficacy of ultrasound-guided radiofrequency acupotomy in early and middle-stage knee osteoarthritis(KOA).Methods A total of 62 patients with KOA were enrolled and then randomly divided into the radiofrequency acupuncture group and the control group.The two groups were treated with radiofrequency acupotomy and conventional acupotomy under ultrasound guidance,respectively.The treatments were conducted once a week,twice in total.The Western Ontario and McMaster Universities Arthritis Index(WOMAC)of all the patients was evaluated before the treatment as well as the day,2 weeks,and 1 month after the treatment.Results Before the treatment,the differences between the two groups in gender,age,body mass index(BMI),WOMAC pain score,WOMAC stiffness score,WOMAC function score,and WOMAC total score were not statistically significant(all P>0.05),indicating the two groups were comparable.On the day,2 weeks,and 1 month after the treatment,the above WOMAC scores of the two groups were lower than those before the treatment,and the differences were statistically significant(all P<0.01).The WOMAC scores of the radiofrequency acupotomy group were lower than those of the control group at the same period,and the differences were statistically significant(all P<0.05).Conclusions For patients with early and middle-stage KOA,ultrasound-guided radiofrequency acupotomy therapy has proven clinical efficacy in relieving pain and improving knee joint function.
