关节镜微创技术对膝关节骨性关节炎患者的临床疗效

Clinical efficacy of arthroscopy of minimally invasive techniques in patients with knee joint osteoarthritis

目的探讨关节镜微创技术治疗膝关节骨J生关节炎的临床效果。方法选择120例膝关节骨性关节炎患者，按随机数字表法分为治疗组和对照组，每组60例，分别行关节镜微创技术治疗以及常规治疗。比较两组手术前后膝关节活动度和膝关节综合评价情况。结果平均随访18个月。治疗组膝关节活动度术前为（62．5±5．5）°，对照组术前为（64．5±6。5）°，两组比较差异无统计学意义（P〉0．05）；治疗组膝关节活动度术后为（92．5±4．2）°，对照组为（70．5±4．5）°，治疗组术后明显优于术前和对照组术后，差异有统计学意义（P〈0．05）。治疗组膝关节综合评价优良率96．7％（58／60），明显高于对照组的73．3％（44／60），差异有统计学意义（P〈0．05）。结论关节镜微创技术操作简便，术后患者恢复快，明显改善膝关节骨性关节炎患者临床症状。

Objective To investigate clinical efficacy of arthroscopy of minimally invasive techniques for treatment of knee joint osteoarthritis. Methods One hundred and twenty patients with knee joint osteoarthritis were selected. The patients were divided into treatment group and control group by random digits table method with 60 cases each. The treatment group was treated with arthroseopy of minimally invasive techniques,and the control group was treated with traditional methods. Results The average followed up time was 18 months. The preoperative knee joint range of motion in treatment group was （62.5 ± 5.5）°,in control group was （64.5 ± 6.5）° ,there was no statistical difference （P 〉 0.05）. The postoperative knee joint range of motion in treatment group was （92.5 ± 4.2）° , in control group was （70.5 ± 4.5 ）° , the postoperative in treatment group was significantly better than that preoperative in treatment group and postoperative in control group, there were statistical differences （P 〈 0.05）. The excellent and good rate in treatment group was 96.7%（58/60） ,in control group was 73.3%（44/60）,there was statistical difference （P 〈 0.05 ）. Conclusion Arthroscopy of minimally invasive techniques has small trauma,is an ideal method to treat knee joint osteoarthritis, and is worth to be applied in clinical.
