1、关节镜下运用LARS人工韧带重建膝前交叉韧带作者:徐乂佳,董启榕,周海滨,陈海南,王向利,汪益,谢宗刚,茅泳涛,郑祖根【摘要】[目的]探讨在关节镜下运用“LARS人工韧带”重建膝前交叉韧带的手术方法和临床疗效。[方法]2006年6月起运用法国LARS膝关节前交叉韧带治疗急性前交叉韧带断裂15例,男11例,女4例,年龄22~51岁(平均26.8岁)o所有患者术前Artoscan均提示前交叉韧带连续信号中断,膝关节Lysholm评分平均50分。治疗在关节镜下完成,股骨隧道口定位在外髒内侧面140°弓形弧的中心点,胫骨隧道口定位在平台内外侧髒间皤之间、髒间窝顶线后2〜4mmo骨隧道直径
2、为7.5mm、LARS韧带直径为8mm.空心挤压螺钉直径为8min。[结果]经平均18个月随访,术后Lysholm评分平均90分,优8例,良5例,可2例,近期优良率为86.6%o本组无术后感染、无韧带自发断裂、无韧带松动并发症。[结论]运用“LARS人工韧带”重建膝前交叉韧带可达到解剖重建,可有效恢复膝关节稳定性;关节镜下手术拥有创伤小、康复快、疗效好等微创特点。【关键词】关节镜;LARS人工韧带;前交叉韧带;重建术Abstract:[Objective]Toexploretheoperatingmethodsandrudimentalclinicaleffectsofrecon
