摘　　要：目的研究前交叉韧带(ACL)胫骨附着处的解剖形态学特点,并探讨ACL胫骨附着处测量值对选择ACL重建方式的意义。方法对10例福尔马林处理的成人膝关节标本进行解剖。在屈伸膝关节时根据ACL纤维张力区分前内束和后外束,然后从胫骨附着处切断韧带,用Photoshop软件测量附着处的相关数据。结果 ACL存在着两个不同的功能束,即前内束和后外束;胫骨附着处的形状不规则,可分为倒三角形、椭圆形及四边形三种;ACL胫骨附着处的前后径与横径分别为(17.89±2.44)mm、(13.85±1.79)mm;前内束和后外束胫骨附着处的面积分别为(101.18±32.28)mm2、(77.61±19.86)mm2;两束中心点连线的距离为(8.03±1.51)mm。结论本研究改进的数字图像测量方法是一种既实用又廉价的测量方法;ACL胫骨附着处测量值可作为选择ACL重建方式的参考。Objective To study the morphological features of the tibial attachment of anterior cruciate ligament（ACL） and discuss the significance of parameters of ACL attachment on suitable styles of ACL reconstruction.Methods Ten formalin fixed adult knee joint specimens were dissected.The anteromedial bundle（AMB） and the posterolateral bundle（PLB） of ACL were identified according to the extension-flexion tensions of ACL.And then,ACL was resected from the tibial attachment site.The anatomical parameters of tibial attachment were measured and analyzed by Photoshop software.Results ACL can be divided into the anteromedial and posterolateral bundles functionally.The irregular shape of the ACL tibial insertion involved in the reversed triangle,oval and quadrilateral shapes.The anteroposterior and transverse diameters of ACL tibial insertion were（17.89±2.44）mm and（13.85±1.79）mm respectively.The area of the tibial attachment of the AMB and the PLB were（101.18±32.28） mm2 and（77.61±19.86）mm2 respectively,and the distance between the gravity points of AMB and PLB was（8.03±1.51）mm.Conclusions This study shows an useful measurement through the improved digital photographs.Parameters of tibial insertion of ACL obtained by this way is a valuable reference for selecting adequate ACL reconstruction skill.
