| 摘 要： | 目的研究前交叉韧带（ACL）在维持膝关节前后稳定和旋转稳定中的作用。方法标本取自新鲜尸体的5只膝关节，分别在ACL完整和切断的情况下对标本施加股四头肌力和腔股关节作用力，采用应变计测量技术和计算机图形处理技术对受载膝关节位移和转角进行测量和图像重建。结果在负载作用下，ACL切断与否对膝关节内、外旋角度的影响很小，但对腔骨前后位移的影响很大。结论ACL是维持膝关节前后稳定的重要结构。

| Abstract: | Aim To study the effect of anterior cruciate ligament (ACL) on the stability of knee joint. Methods Five knee joints, taken from fresh cadavers, were used. The contraction force of femoral que adriceps muscle and the action force of tibiofemoral joint were applied to the knee joint with intact ACL and then with amputated ACL, and the anteroposterior displacement and rotation angle of the knee joints were measured with strain measurement tech nique and reconstructed the image with computer image processing technique. Results On loading, whether or not the ACL was amputated, the changes of rotation angle were small but the changes of anteroposterial displacement were large. Conclusion ACL is an important structure for maintaining the anteroposterial stability of the knee joint. |
