射频汽化仪在关节镜下治疗膝关节疾病中的应用

目的探讨射频汽化仪在关节镜下治疗膝关节疾病的疗效。方法采用Arthrocare 2000射频汽化仪对126例膝关节疾病进行关节镜手术，其中半月板损伤72例，滑膜炎20例，骨性关节炎15例，髌骨半脱位8例，滑膜皱襞综合征6例，前交叉韧带部分损伤5例。结果126例术后3个月均获随访，无一例切口或关节感染。术后3个月膝关节功能按Neer评分标准：优82例，良35例，可9例，差0例。优良率92．9％。结论使用射频汽化仪在关节镜下治疗膝关节疾病能使手术简便且精确，有效地止血，创伤小，同时能减少对邻近组织的损伤，术后膝关节功能恢复良好。

Application of radiofrequency vaporization in arthroscopic treatment of knee disorders

Objective To investigate effects of radiofrequency vaporization in arthroscopic treatment of knee disorders. Methods Arthroscopic surgery was conducted in 126 consecutive cases of various knee disorders by using the Arthrocare 2000 System, includng 72 cases of meniscus injury, 20 cases of synovitis, 15 cases of osteoarthritis, 8 cases of patella subluxation, 6 cases of synovial syndrome, and 5 cases of anterior cruciate ligament rupture. Results All the patients were followed postoperatively. Knee function evaluation with the Neer Scores showed excellent outcomes in 82 cases, good in 35 cases, and fair in 9 cases, the rate of excellent-or-good outcomes being 92.9%. Conclusions Application of radiofrequency vaporization under arthroscopy for knee joint disorders has advantages of simple and accurate performance, effective hemostasis, minimal invasion, and quick recovery of joint functions.
