摘要
目的比较关节镜下射频汽化仪与机械松解髌周支持带治疗膝关节伸直位僵直的作用。方法在关节镜下采用射频汽化仪行膝关节粘连的髌周支持带松解术,治疗伸直位膝关节僵直24例,与同期的钩刀行膝关节粘连髌周支持带松解术治疗的36例进行比较,全部病例获得6～24个月(平均12.4个月)随访。结果所有病例术前检查均存在内外侧支持带的挛缩,关节镜下行髌周支持带松解,射频汽化仪组膝关节活动度优于钩刀组(P<0.01),髌骨活动度2组无显著差异(P>0.05)。结论关节镜下射频汽化仪行髌周支持带松解对膝关节粘连存在内外侧支持带挛缩是首选治疗方法。
Objective To analyze the difference between the arthroscopic radiofrequency and the arthroscopic mechanical lysis of the peripatellar retinaculum contracture in the treatment of knee extension stiffness. Methods Randomized control and prospective case study were designed, with 24 patients in the arthroscopic radiofrequency treatment group and 36 in the arthroscopic mechanical lysis group （the control）. All the patients were followed up for an average of 12.4 months （ranging from 6 to 24 months）. Results All the patients had both lateral and medial retinacula contracture under perioperative examination. In the operation of arthroscopic lysis of the peripatellar retinaculum contracture, the radiofrequency treatment group was better than the mechanical lysis group in the improvement of the knee motion, and the difference of patellar motion improvement was not significant. Conclusion Arthroscopic radiofrequency lysis of the perlpatellar retinaculum contracture is the first choice in the treatment of knee extension stiffness caused by both medial and lateral retinaeulum contracture.
