摘　　要：目的总结股骨外侧髁切迹征(lateral femoral notch sign,LFNS)与前交叉韧带(anterior cruciate ligament,ACL)断裂的关系。方法回顾近年国内外LFNS相关研究文献,对其发生机制、诊断ACL断裂的标准和影响因素等方面进行总结分析。结果LFNS的出现与膝关节旋转稳定性相关,作为ACL断裂的间接征象具备较高的临床诊断价值,特别是在诊断ACL断裂伴外侧半月板损伤方面。结论LFNS用于诊断ACL断裂的标准和影响因素等方面尚存在争议,有待进一步深入研究。Objective To summarize the relationship between lateral femoral notch sign(LFNS)and anterior cruciate ligament(ACL)rupture.Methods The relevant literature of LFNS at home and abroad in recent years was retrospectively reviewed,and its mechanism,diagnostic criteria and influencing factors in diagnosis of ACL rupture were summarized and analyzed.Results The LFNS is associated with rotational stability of the knee.As an indirect sign of ACL rupture,the LFNS has high clinical diagnostic value,especially the diagnosis of ACL rupture with lateral meniscus injury.Conclusion The diagnostic criteria and influencing factors of LFNS in diagnosis of ACL rupture are still unclear and controversial,which needs further study.
