双极关节腔内脉冲射频联合臭氧注射治疗膝骨性关节炎的临床疗效

Clinical efficacy of bipolar intra-articular pulsed radiofrequency combined with ozone injection in treating knee osteoarthritis

目的观察双极关节腔内脉冲射频(IAPRF)联合臭氧注射治疗膝骨性关节炎(KOA)的临床疗效。方法140例KOA患者随机分为两组,每组70例。联合组予以双极IAPRF联合臭氧注射治疗,对照组仅予以双极IAPRF治疗。分别于治疗前及治疗后1周、6个月和12个月比较两组患者VAS疼痛评分和骨关节炎指数(WOMAC)评分的差异。结果两组治疗前VAS疼痛评分和WOMAC评分差异均无统计学意义(P>0.05)。两组治疗后1周、6个月和12个月VAS疼痛评分和WOMAC评分均低于治疗前,且联合组优于对照组(P<0.05)。结论与双极IAPRF治疗比较,双极IAPRF联合臭氧注射治疗更能减轻KOA患者疼痛,改善膝关节功能。

Objective To observe the clinical efficacy of bipolar intra-articular pulsed radiofrequency(IAPRF)combined with ozone injection in the treatment of knee osteoarthritis(KOA).Methods A total of 140 KOA patients were divided into two groups with 70 cases each,who were treated with bipolar IAPRF combined with ozone injection(group A)or bipolar IAPRF alone(group B).The VAS pain score and osteoarthritis index(WOMAC)score were compared between the two groups before and 1 week and 6 and 12 months after treatment.Results There were no significant differences in VAS pain score and WOMAC score between the two groups before treatment(P>0.05).The VAS pain score and WOMAC score were lower one week and 6 and 12 months after treatment than those before,which were lower in group A than those in group B(P<0.05).Conclusion Compared to bipolar IAPRF alone,bipolar IAPRF combined with ozone injection is more effective in relieving pain and improving knee joint function in the patients with KOA.
