The major attachments of the posterior horn of the lateral meniscus are the popliteomeniscal fascicles and the meniscofemoral ligaments.

This posteroblique illustration shows the relationship of meniscofemoral ligaments, lateral meniscus, and PCL.

The meniscofemoral ligaments originate from the posterior horn of the lateral meniscus and insert onto the lateral aspect of the posterior medial femoral condyle, with the Humphry ligament anterior to the posterior cruciate ligament (PCL) and the Wrisberg ligament posteriorly

Occasionally the meniscofemoral Humphry ligament can appear as a large low-signal-intensity structure within the notch that may resemble a displaced meniscal fragment

 

The meniscofemoral ligaments may mimic a peripheral vertical longitudinal tear, but can be differentiated by following these structures on serial images
