关节镜下射频汽化仪治疗半月板损伤的应用

Clinical application on the radiofrequency coblation technology in treatment of meniscal injury under arthroscopy

目的 探讨关节镜下射频汽化仪与常规器械治疗半月板损伤术后近期疗效。 方法 将 3 8例膝关节半月板损伤患者按纳入和剔除标准分为常规器械 (CI)和射频汽化仪 (RF)组 ,比较和分析两组手术时间、术后关节积液、膝关节屈伸度改善程度、术后临床症状改善程度和膝关节功能恢复程度。 结果 射频汽化仪组的手术时间为 ( 2 8 5 0± 2 97)min ,明显少于常规器械手术组的 ( 4 1 0 0±7 49)min ,且RF组术后关节积液发生较少 ,为 ( 6 0± 1 41)ml,RF组术后膝关节活动度改善程度为( 2 5 61± 12 62 )° ,膝关节功能恢复程度为 ( 4 0 0± 10 5 5 )分 ,均优于CI组的 ( 15 5 5± 10 0 1)°和 ( 3 2 3 5± 5 71)分 结论 使用射频汽化仪在关节镜下行半月板成形具有手术操作更加简单易行、创伤小和术后膝关节功能恢复良好的优点。

Objective To observe and compare the short-time outcome in meniscal lesions with radiofrquency coblation technology or normally mechanical technology under the arthroscopy. Methods Thirty-eight patients with mentisci injury was selected, and divided into radiorfequency and normal group according to the standards. The patients in former group were treated with menisci reformation by radiofrequency, while in later group by menisci parthial excision. Some criteria were analysised and evaluated by comparison of operation-time, post-operation effusion of joint and improvement on the degrees of flexion and extension, clinical symptoms, functional restoration of knee joint of both groups. Results The average operation-time in radiofrequency group was less than that of normal group apparently. It was less possible for effusion of joint happened in the radiofrequency group after operation. The improvement on the degrees of flexion and extension and functional restoration of joint in the radiofrequency group exceeded in another group. Conclusion The radiofrequency under the arthroscopy is simper and less leading the surrounded tissue injury with more excellent functional restoration fo knee joint, also it has more advantage than the normal menisci partial excision mechanically.
