Abstract:
The anatomical and functional details of the anterior cruciate ligament (ACL) of the knee joint were studied on 55 normal cadaver knees of adults.ACL is made up of multiple fascicles, the basic unit of which is collagen. It is attached to the medial surface of the lateral femoral condyle and front of the anterior tibial spine. ACL is narrow in the middle and fans out at the attachments. The fascicles of ACL have been summarily divided into two groups: the anterior medial portion (AMP) and the posterior lateral portion(PLP). The tension of AMP is different from that of PLP during movement of the knee. ACL restricts the anterior drawer sign, and the internal and external rotation of the knee. AMP acts with the knee in flexion and PLP in extension. ACL restricts hyperextension, too. The function of ACL is related to its morpholcgical structure and the anatomy of the attachments. Rupture of ACL may result in instability of the knee, and injuries to the different components of ACL may produce different signs.
