目的 探讨高频电刀和离子冷凝刀在膝关节镜手术中的作用,对比术后及近期疗效.方法 回顾性分析2005年1月至2009年1月我院关节镜治疗半月板损伤88例,所有病例行滑膜清理并半月板不同程度切除.其中前30例使用高频电刀,后58例为离子冷凝刀,后者包括韧带皱缩术19例.术后统计关节腔置管引流量及膝关节功能评分等.结果 离子冷凝刀治疗组对比高频电刀组术后1周Lysholm评分（65.50±14.71）与（51.34±6.76）及6个月（87.29±5.41）与（79.71±15.02）,P〈0.05,差异有统计学意义.离子冷凝刀治疗组组内Lysholm评分（87.29±5.41）与（65.50±14.71）,P〈0.05差异有统计学意义.结论 膝关节镜手术中,离子冷凝刀对比高频电刀优势明显.离子冷凝刀可以更有效止血,彻底清除增生的滑膜,减少术后膝关节肿胀程度,皱缩韧带增强膝关节的稳定性,为膝关节术后早期功能康复提供了最佳时机,近期随访效果明确.
Objective To study the clinical evaluation of using radiofrequency and high frequency electrotome in knee arthroscopy. Make comparison with the post - surgical recovery and recent treatment. Methods A retrospective analysis was performed on 88 patients operated by arthroscopy between Jan 2005 and Jan 2009. All patients underwent partial, subtotal or total meniscectomy removal and cleaning of synovium. The first 30 patients were performed with high frequency electrotome and the remaining with radiofrequency, including 19 underwent anterior cruciate ligament radiofrequency shrinkage. The grading on knee function was made before and after surgery and 6 months postoperatively. Results Compared with high frequency electrotome, radiofrequency in the knee arthroseopy had superior performance in one week and 6 months respctively（ P 〈 0.05 ） by Lysholm. An intraclass disparity existed in the group of radiofrequency as the Lysholm is better shown in 6 months than in one week（ P 〈 0.05 ）. Conclusion Radiofrequency in arthroscopy has the advantages of less bleeding, swelling and more stability of knee and quick recovery. The results of recent follow - ups are obvious.
