The sagittal images progress from lateral to medial and demonstrate the ligament of Wrisberg, passing posterior to the PCL and continuing into the superior margin of the peripheral meniscal tear segment created by the longitudinal tear of the posterior horn of the lateral meniscus. The torn ACL is seen on the sagittal views Note the contusion bone marrow edema at the posterior lateral tibial pla..

The meniscofemoral ligaments may mimic a peripheral vertical longitudinal tear Due to variability in the ligament attachment site, this cleft can extend variably far, and as a result the discrimination between a true tear and a 'pseudo-tear' may pose a challenge. Wrisberg rips, also known as zip tears or zipper tears, are longitudinal vertical meniscal tears. when the average attachment site lie..

The pseudotear caused by the high signal band located between the MFLs and the posterior horn of the lateral meniscus. Wrisberg rip is the longitudinal tear of the posterior horn of the lateral meniscus. Differentiation of this tear from the normal pseudo-tear is made by lateral extension of the cleft between the meniscus and meniscofemoral ligament by 1.4 cm or more lateral to the lateral margi..

Wrisberg rip, also known as zip tear or zipper tear is the longitudinal tear of the posterior horn of the lateral meniscus. Wrisberg rip occurs at the junction of the meniscofemoral ligament and the posterior horn of the lateral meniscus. Axial oblique reformatted image demonstrates the course of the ligament of Humphrey anterior to the PCL (blue arrows) as it joins to the meniscal fragment peri..

Posterior oblique drawing demonstrates PCL, LM, meniscofemoral ligaments (Humphry ligament and Wrisberg ligament) 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 Wrisber..

There is a close association between ACL tears and peripheral longitudinal tears in the posterior horns of both the medial and lateral menisci. Acute ACL injury is associated with more lateral meniscal tears, while chronic ACL deficiency is associated with more medial meniscal tears,many of which require meniscectomy. So early ACL reconstruction is recommended also for the prevention of secondar..

Anomalous insertion of the medial meniscus (AIMM) into the anterior cruciate ligament (ACL) is rare.The AIMM has the same anatomical description as the anteromedial meniscofemoral ligament It appears as a linear band isointense to the ACL and meniscus, which runs parallel to the ACL and demonstrates a hyperintense gap between it and the ACL On MRI, this anomaly may be misinterpreted as an ACL te..
