From: Significance of the broad non-bony attachments of the anterior cruciate ligament on the tibial side
The relationship between the ACL attachment and the anterior and posterior horns of LM. (A) The superior aspect of the tibial side of ACL and LM. The superficial layer of the outer fibers of the anterior horn of LM (black circle) is connected to the ACL fibers. (B) After removing the ACL, while marking the margin of its attachment with a black pen. The deep layer of the outer (black dot) and inner fibers (white dot) of the anterior horn of LM extend into the intercondylar area and fit into the concave lateral border of the ACL attachment. The posteromedial crus (white star) is wrapped around the posteromedial side of ACL, and its attachment edge coincides with the medial border of the ACL attachment. (C) After removing the attachment of the posteromedial crus of the posterior horn of LM and flipping it posteriorly. The attachment edge of the anterolateral crus (black star) of the posterior horn of LM coincides with the posterior border of the ACL attachment. AC, articular cartilage; ACL, anterior cruciate ligament; LM, lateral meniscus; MM, medial meniscus; PCL, posterior cruciate ligament.
