Figure 2.

The anterior lateral (AL) meniscal root is shown to run deeply beneath and overlap with the anterior cruciate ligament (ACL), as observed in all knees. The anterior medial (AM) meniscal root is depicted with supplemental fibers (SFs) that were observed to be anterior and distal to the central root. Anterior meniscal root structure is also described in relation to pertinent bony and soft tissue landmarks. AC, articular cartilage; LTE, lateral tibial eminence; MTE, medial tibial eminence; PL root, posterior lateral meniscal root; PM root, posterior medial meniscal root; TT, tibial tuberosity.
