等离子刀与机械刨削在治疗膝关节类风湿性关节炎中的作用分析

Comparison radiofrequency with mechanical gouging in the treatment of knee rheumatoid arthritis

目的:比较等离子刀与刨削系统在治疗膝关节类风湿性关节炎中的作用。方法:采用随机对照前瞻性研究,等离子刀治疗组21例,机械刨削对照组17例,全部病例获得6￣39个月(平均19.5个月)的随访。随访结果采用Lysholm膝关节功能评分。结果:对美国风湿病学会RA分期处于Ⅰ期和Ⅱ期的病例,等离子刀治疗组的膝关节功能评分优于对照组(P<0.05);而对于Ⅲ期的病例,等离子刀治疗组与对照组差异无统计学意义(P>0.05)。结论:等离子刀技术对RA分期处于Ⅰ期和Ⅱ期的病例是首选治疗方法。

Objective：To analyse the differences between radiofrequency and mechanical gouging in treatment of knee rheumatoid arthritis. Methods：Randomized control and prospective case study was designed, with 21 cases in the radiofrequency treatment group and 17 cases in the mechanical gouging group （control group）. All the cases were followed up for an average of 19.5 months（ranging 6 to 39 months） according to Lysholm knee function evaluation score. Results ：The Lysholm scores in the treatment group were superior to those in the control group in cases at stage Ⅰ and Ⅱ according to ARA staging system （P 〈 0.05）, while there were no statistically significant differences between the two groups in cases at stage Ⅲ （P 〉 0.05）.Conclusion： Radiofrequency is the first choice in treatment of knee rheumatoid arthritis at stage Ⅰ and Ⅱ.
