目的 通过关节镜下处理膝关节纤维性僵直的疗效分析,对该术式疗效进行探讨。方法 对36例术后膝关节僵直的病人进行膝关节镜下关节内粘连带、瘢痕、挛缩关节囊松解,粘连股四头肌与股骨剥离,术中观察及术后随访。结果 关节活动度从术前平均42.14°,术中即时屈膝平均提高到116.22°,术后6周随访平均提高到136.45°,术后3个月随访平均提高到142.36°,2例并发关节内血肿。结论 通过关节镜技术治疗关节僵直病人能达到较好疗效,创伤小,功能恢复快。
Objective To evaluate the effect of arthroscopy in treatment of knee fibrous stiffness. Methods 36 cases of postoperative knee stiffness underwent arthroscopic lysis of intraarticular adhesion, scar, joint capsule adhesion and the adhesion between quadriceps femoris and femur. Result The joint activity was increased to 116.22 degrees during the operation from preoperative 42.14 degrees, and was 136.45 degrees, 142.36 degrees at 6 weeks and 3 months, respectively. Intraarticular hematoma occurred in 2 cases. Conclusion Arthroscopy in treatment of ankylosis patients can achieve good curative effect, small trauma and fast recovery of function.
