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 lies approximately 14 mm laterally from the lateral edge of the PCL and that any cleft extending farther is suspicious for a tear.

Apparent far lateral meniscal extension of a meniscofemoral ligament should be considered as a possible PHLM tear, especially in the setting of an ACL tear
