* 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.
* The fascicles not only form the hiatus, which allows the popliteus tendon an avenue to course intra-articularly and maintain the integrity of the joint but stabilize and control the motion of the posterior horn
The superior (posterosuperior) and inferior (anteroinferior) popliteomeniscal fascicles can be identified in the coronal and sagittal planes.
A third or posteroinferior popliteomeniscal fascicle is a medial aponeurotic extension from the popliteus musculotendinous area to the inferomedial aspect of the posterior horn of the lateral meniscus.
Tearing of the posterosuperior fascicle is highly associated with tears of the posterior horn of the lateral meniscus, with a sensitivity, specificity, and positive predictive value of 89%, 96%, and 79% respectively.
