The transverse ligament is a fibrous band that connects the anterior horns of the medial and lateral menisci. Axial and sagittal images demonstrate the course of the transverse ligament as a low-signal-intensity band traversing Hoffa’s infrapatellar fat pad. The transverse ligament can simulate an oblique tear adjacent to the anterior horn of the lateral meniscus © 2021 MSK MRI Jee Eun Lee All R..

Peripheral attachments of the lateral meniscus are less extensive and generally more lax than on the medial side , allowing greater mobility of the lateral meniscus, and likely contributing to the relatively increased frequency of medial meniscal tears. The coronary ligaments (meniscotibial ligaments) provide an attachment from the posterior horn of the lateral meniscus to the tibia. This fat-su..

The meniscofemoral ligaments originate from the posterior horn of the lateral meniscus and insert onto the lateral aspect of the posterior medial femoral condyle, anterior to the PCL. notice, This cleft between the meniscus and meniscofemoral ligament may be mistaken for a meniscal tear. © 2021 MSK MRI Jee Eun Lee All Rights Reserved. #MSKMRI, #virtualMRI, #radiologist, #Knee_MRI, #MSKMRI_Knee, ..

•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 Subset of..

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 femo..

The popliteomeniscal fascicles consist of the anteroinferior(strongest), posterosuperior, and posteroinferior. posteroinferior The posteroinferior popliteomeniscal fascicle (arrow) is the least consistently visualized of the fascicles The posteroinferior fascicle is more medially located, and extends from a medial aponeurotic extension of the popliteus tendon to attach to the lateral meniscus ne..

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 popliteal hiatus shows relatively symmetric posterosuperior and anteroinferior fascicles. More medial section of the hiatus shows the normal deficiency of the anteroinferior popliteomeniscal fascicle. le..

The anteroinferior and posterosuperior fascicles were seen on MRI in 97% of patients who had a normal lateral meniscus at arthroscopy Although 45 degree oblique coronal images have been recommended for visualization of the popliteomeniscal fascicles , these structures are often well visualized during the review of routine sagittal acquisitions of the knee The anteroinferior popliteomeniscal fasc..
