摘　　要：目的应用MRI对股骨Blumensaat线的测量,为重建前交叉韧带(anterior cruciate ligament,ACL)提供参考。方法通过选择100例正常的膝关节伸直位磁共振检查结果,在适当的切面上绘制Blumensaat线延长线与胫骨平台的交点,测量其在胫骨矢状径位置及其与后交叉韧带(posterior cruciate ligament,PCL)的距离,并与ACL胫骨侧生理止点中心和PCL的距离比较。结果 Blumensaat线延长线与胫骨平台的交点在胫骨矢状径上距前缘(51.9±7.3)%,与PCL距离(14.2±2.5)mm,较ACL生理止点中心靠后。结论为避免髁间窝前方撞击,重建ACL胫骨侧止点定位于胫骨平台生理性止点中心后方或PCL前方8～10mm,个别人需更后方。Objective to measure Blumensaat′s line of femur on MRI to provide reference to locate the tibial insertion in ACL（Anterior Cruciate Ligament,ACL）reconstruction.Methods 100 patients who had no obvious abnormality on MRI was chosen.The Blumensaat′s line was lengthened to cross the tibial plateau.The distances between the crossing point and the midpoint of the ACL tibial insertion and the posterior plateau border were measured.The distances between the anterior and the posterior plateau border were measured.Results The crossing point was located at anterior（51.9±7.3）% of the tibial plateau sagittal line or（14.2±2.5） mm forwards the anterior border of the PCL,where is behind the medpoint of the ACL tibial insertion.Conclusion To avoid intercondylar fossa impingement,the tibial insertion of the reconstructed ACL should be located behind the middle point of tibial insertion or 8~10 mm before the PCL.The tibial insertion of the reconstructed ACL should be located more backward in some patients.
