射频辅助关节镜有限清理术治疗膝骨性关节炎的效果观察

目的: 探讨射频技术辅助关节镜有限清理术对膝骨性关节炎的治疗效果.方法: 将48例膝骨性关节炎患者随机分为射频组24例经关节镜采用射频技术治疗;常规组24例经关节镜采用常规的手术器械和电动刨削器治疗.比较2组患者术前、术后1年Lysholm评分和术后2周内关节积液量.结果: 2组术前Lysholm评分差异无统计学意义(P >0.05).2组患者术后Lysholm评分均较术前明显提高(P< 0.01),而且2组患者术后1年Lysholm评分差异有统计学意义(P< 0.01);射频组术后2周内膝关节积液量明显少于常规组(P< 0.01).结论: 射频技术辅助膝关节镜有限清理术治疗膝骨性关节炎有助于提高疗效,值得推荐.

Effect of arthroscopic debridement combined with radio frequency energy in the treatment of knee osteoarthritis

Objective: To explore the effects of arthroscopic debridement combined with radio frequency energy in the treatment of knee osteoarthritis.Methods: Forty-eight patients with knee osteoarthritis were randomly divided into the radio frequency group and traditional apparatus group(24 cases each group),which were treated with arthroscope combined with radio frequency and arthroscopic traditional apparatus,respectively.The preoperative and postoperative 1-year Lysholm score and joint effusion quantity at 2 weeks after operation between two groups were compared.Results: The difference of preoperative Lysholm score in two groups was not statistically significant(P >0.05).The postoperative Lysholm scores in two groups were significantly higher than that in preoperation(P< 0.01).The difference of postperative 1-year Lysholm score in two groups was statistically significant(P< 0.01).The joint effusion quantity at 2 weeks after operation in radio frequency group was less than in that in traditional apparatus group(P< 0.01).Conclusions: The radio frequency energy can effectively improve the outcome of the arthroscopic debridement in the treatment of knee osteoarthritis,which is worth to recommend.
