| 目的：探讨前交叉韧带(anterior cruciate ligament, ACL)在膝关节不同屈曲角度时的方位角变化，为ACL损伤诊断和重建研
究提供解剖学支持。方法：成人膝关节标本10 具，解剖观察ACL形态，用Photoshop软件测量膝关节不同屈曲角度下ACL 方位
角变化。结果：0° 、30° 位膝关节中ACL胫骨角大于ACL股骨角，有显著性差异(P<0.01)；60° 、90° 位膝关节中的ACL胫骨角
小于股骨角，有显著性差异(P<0.01)。膝关节0° 、30° 、60° 、90° ACL胫骨角由大渐小，各角度间均有显著性差异(均P<0.01)。膝
关节0° 和30° 的ACL股骨角比60° 和90° 时小，有显著性差异(均P<0.01)，0° 与30° 间无显著性差异(P>0.05)，60° 小于
90° ，有显著性差异(P<0.01)。结论：ACL于膝关节0° 和30° 位时，后外侧束（posterolateral bundle, PLB）发挥主要作用，ACL诊
断或重建主要参考胫骨角；60° 、90° 时ACL 前内侧束（anteromedial bundle, AMB）发挥主要作用，ACL 诊断或重建主要参考股
骨角。ACL方位角可作为ACL损伤诊断和手术重建的重要参考。 |

| Objective:To investigate the azimuth angle change of anterior cruciate ligament (ACL) in different knee flexion Angle
and to provide anatomical support for diagnosis and reconstruction of ACL injury research.Methods:The specimens in this experiment
are 10 normal knee joints of adult. Measuring the ACL azimuth angle when the knee joint located at 0° , 30° , 60° , and 90°
respectively.Results:When the knee locates at 0° and 30° , the included angle of ACL and medial meniscus is bigger than the included
angle of ACL and femur (P<0.01). When the knee locates at 60° and 90° , the included angle of ACL and medial meniscus is smaller
than the included angle of ACL and femur (P<0.01). The included angle of ACL and medial meniscus are ordered frombig to small with
the sequence as 0° , 30° , 60° , and 90° (P<0.01). The included angle of ACL and femur are ordered as 90° , 60° , 30° and 0° . The
angle at 0° and 30° has no significant difference (P>0.05).Conclusion:The PLB plays a major role when the knee is at 0° and 30° .
In ACL diagnosis or reconstruction, the included angle of ACL and medial meniscus should be a main reference factors. The AMB play a
major role when the knee at 60° and 90° . In ACL diagnosis or reconstruction, the included angle of ACL and femur should be a main
reference factor. |
