Beginning at the lateral aspect of the lateral compartment, the anteroinferior popliteomeniscal fascicle is seen to course from the inferior aspect of the lateral meniscus posteroinferiorly to blend with fibers of the popliteofibular ligament.

 

​​The posterosuperior popliteomeniscal fascicle is visualized medially to the anteroinferior popliteomeniscal fascicle as the popliteus tendon penetrates the meniscocapsular junction.

 

The popliteomeniscal fascicles arise from the periphery of the posterior horn of the lateral meniscus and form a posterolateral meniscocapsular extension, which creates the popliteus hiatus. 

 

As the popliteus tendon passes laterally, it passes beneath the posterosuperior fascicle and above the anteroinferior fascicle

The normal deficiency of the inferior popliteomeniscal fascicle (to accommodate the passage of the popliteus tendon) occurs at the location medial to the body of the lateral meniscus.
