关节镜技术应用于中老年膝关节骨关节炎治疗中疗效分析

Therapeutic Effect of Arthroscopy in the Treatment of Knee Osteoarthritis in Middle-aged and Elderly Patients

目的研究中老年膝关节骨关节炎中关节镜技术的应用价值。方法以2015年9月—2017年12月该院接诊的中老年膝关节骨关节炎病患70例为研究对象,将之采用电脑随机双盲法分成实验和对照两组(n=35)。当中,实验组应用关节镜技术进行治疗,对照组接受常规药物治疗。分析两组疼痛程度的缓解情况,并对各组的临床总有效率做出比较。结果实验组治疗后6个月的生活质量评分为(90.24±3.85)分,优于对照组的(81.69±4.27)分,组间比较差异有统计学意义(t=8.7979,P<0.05)。实验组的临床总有效率为97.14%,比对照组的74.29%高,组间比较差异有统计学意义(χ^2=7.4667,P<0.05)。实验组术后1个月的VAS评分为(3.49±1.32)分、术后3个月的VAS评分为(2.09±0.87)分、术后6个月的评分为(0.98±0.36)分,比对照组的(5.04±1.36)分、(4.86±1.72)分以及(2.52±0.93)分低,组间比较差异有统计学意义(t=2.4482,8.5019,9.1359,P<0.05)。实验组对治疗效果的满意度为97.14%,比对照组的77.14%高,组间比较差异有统计学意义(χ^2=6.2477,P<0.05)。结论通过采取关节镜技术对中老年膝关节骨关节炎病患进行治疗,可显著提升其临床疗效,间其疼痛程度,改善生活质量,建议临床推广。

Objective To study the application value of arthroscopy in middle and old aged knee osteoarthritis.Methods Seventy patients with middle-aged and elderly knee osteoarthritis who were admitted to our hospital from September 2015 to December 2017 were enrolled in the study.They were divided into experimental group and control group by computerized double-blind method(n=35).Among them,the experimental group was treated with arthroscopic techniques and the control group was treated with conventional drugs.The relief of pain levels in the two groups was analyzed and the total clinical effectiveness of each group was compared.Results The quality of life score of the experimental group at 6 months after treatment was(90.24±3.85)points,which was better than that of the control group(81.69±4.27)points.The difference between the two groups was statistically significant(t=8.797 9,P<0.05).The total clinical effective rate of the experimental group was 97.14%,which was higher than that of the control group(74.29%).The difference between the two groups was statistically significant(χ^2=7.466 7,P<0.05).The VAS score of the experimental group was(3.49±1.32)points at 1 month postoperatively,(2.09±0.87)points at 3 months postoperatively,and(0.98±0.36)points at 6 months postoperatively.In the control group,(5.04±1.36)points,(4.86±1.72)points and(2.52±0.93)points were lower,and the difference between the groups was statistically significant(t=2.448 2,8.501 9,9.135 9,P<0.05).The satisfaction rate of the experimental group was 97.14%,which was higher than that of the control group(77.14%).The difference between the two groups was statistically significant(χ^2=6.247 7,P<0.05).Conclusion The treatment of middle-aged and elderly knee osteoarthritis patients by arthroscopic techniques can significantly improve their clinical efficacy,the degree of pain and improve the quality of life,and recommend clinical promotion.
