Fascicle Location and Appearance
Anteroinferior
Popliteomeniscal Fascicle
Visible on sagittal slices near the fibular head; extends posteroinferiorly from the lateral side of the lateral meniscus (LM) and merges with the popliteus tendon; conjoined attachment with the popliteofibular ligament at the fibula’s styloid process; variable appearance.
Posterosuperior
Popliteomeniscal Fascicle
Extends from the superior margin of the LM's peripheral posterior horn to the posterior joint capsule, above the popliteus tendon; visualized medial to the anteroinferior fascicle, especially as the popliteus tendon penetrates the meniscocapsular junction.
Posteroinferior
Popliteomeniscal Fascicle
Least consistently visualized; near the posterior horn's root; extends from the inferior margin of the LM posteroinferiorly to a capsular extension of the popliteus tendon; in cross-section, resembles a torn inferior flap of the meniscus.
