【摘要】 目的 报告膝关节后室游离体关节镜检查的结果,探讨对游离体行直径4mm、30°关节镜取出术的方法。方法 对膝关节正侧位 X线片示后室有异常高密度影的骨关节炎患者,使用4mm、30°关节镜经后外及后内入口检查,并分别在其前方1～1.5cm添加辅助入口,对发现的游离体行镜视下取出术。术后观察小腿和足部痛觉,踝及足趾的跖背屈运动,足背动脉搏动并行膝侧方应力试验。结果1999年1月～2000年12月,在364例膝关节镜手术中,对17例在X线片上可见膝关节后室游离体的骨关节炎患者,行后外和后内入口的关节镜检查。9例在后外室发现游离体,行关节镜视下取出术。后内室均未发现游离体。术后1例X线检查发现后外侧皮下残留1枚游离体,1例出现后外侧切口血肿,无一例出现神经、血管和韧带并发症。结论 用4mm、30°关节镜行膝关节后室检查及添加辅助口行镜下游离体取出术安全可行。更多还原

【Abstract】 Objective To report the method and outcomes ot arthroscopic examination and removal of the.loose bodies from the posterior compartments of the knee. Methods Four mm 30° arthroscope was used to examine the patients with osteoarthritic loose body in the politeal fossa on the preoperative roentgenograms via posterolateral and posteromedial portals. An assistant portal at 1 - 1.5 cm in front of the standard portals was made, and loose bodies were removed arthroscopically. Postoperative algesia on the leg and foot, active flexion and extension of the malleolus, toe and phalanxes, and the lateral stress test of the knee were observed. Results Of the three hundred and sixty-four cases undergone knee arthroscopy during January 1999 to December 2000, 17 case had osteoarthritis and loose bodies in the posterior compartment on the roentgenograms. Loose bodies were found in the posterolateral portal in 9 cases, which were removed arthroscopically. Howerver, no loose body was found via the posteromedial portal. The mean duration of follow-up was 14. 88 months. Except one case with subcutaneous loose body was overlooked and one patient developed hematoma, there was no neurovascular or ligamentous complications. Conclusion It is safe and possible to use 4 mm 30° arthroscope to examine the posterior compartments of the knee and to remove loose bodies.更多还原
