From: Significance of the broad non-bony attachments of the anterior cruciate ligament on the tibial side
Three-dimensional relationships of the ACL with the AC and LM. (A) The superior aspect of the tibial side of the ACL and surrounding structures, reconstructed based on the serial histological sections (interval = 0.2 mm). The ACL is medially attached to the articular cartilage and laterally connected to the superficial layer of the outer fibers of the anterior horn of LM (black circle). (B) The posterolateral aspect of (A). (C) After removal of the ACL from (A). The deep layer of the outer (black dot) and inner fibers (white dot) extend into the intercondylar area. (D) The posterolateral aspect of (C). The articular cartilage in the area where the ACL is attached has an inclined surface facing laterally. AC, articular cartilage; ACL, anterior cruciate ligament; LM, lateral meniscus; MM, medial meniscus.
