【摘要】 目的关节镜下以半腱肌肌腱重建膝前交叉韧带(ACL),分析影响治疗效果的因素。方法关节镜下4股半腱肌肌腱修复膝ACL损伤25例。膝前小切口取半腱肌肌腱对折后成4股,分别建立胫骨隧道及股骨隧道,重建膝ACL的解剖结构和生理功能,术后早期行功能锻练。结果 25例均获随访,时间12~36个月。术前Lachman征(+),术后Lachman征(-)。Lysholm评分从术前27~71(53±13.22)分提高到术后78~94(87±3.42)分。结论半腱肌肌腱具有良好的抗拉强度和刚度,在关节镜下用4股半腱肌肌腱重建膝ACL是一种疗效可靠的治疗方式。更多还原

【Abstract】 Objective To analyze the influential factors on effect of arthroscopic anterior cruciate ligament(ACL)reconstruction with semitendinosus.Methods A retrospective analysis was performed in 25 patients of arthroscopic ACL reconstruction with semitendinosus autograft.Through anterior knee small incision,semitendinosus was folded into four strands.After respectively established the tibia tunnel and femur tunnel,the anatomical structure and ACL physiological function reconstruction was performed,and followed by early postoperative function exercise.Results All of the 25 patients were followed up for 12 ~36 months.Preoperative Lachman test was(+),and postoperative Lachman test was(-).Preoperative Lysholm score was 27～71(53±13.22)points,which raised to postoperative 78～94(87±3.42)points.Conclusions Semitendinosus autograft has good tensile strength and rigidity.Under the arthroscope,using four strands of semitendinosus for reconstruction of knee anterior cruciate ligament is a reliable treatment.更多还原
