Ramp lesion (meniscus)
Updates to Article Attributes
Ramp lesion lesions areis defined defined as a longitudinal tear of the peripheral attachment of the posterior horn of the medial meniscus at the meniscocapsular junction 1. It is a type of meniscal injuriesinjury affecting the posterior horn medial meniscus, most frequently in the setting of pivot shift mechanism of injury (e.g. anterior cruciate ligament (ACL) injuries) 2.
As it is a minor injury and has a hidden location using standard anterolateral and anteromedial arthroscopic portals, its identification guides the orthopedicianorthopedic surgeon to identify it on arthroscopy by probing of the posterior horn of the medial meniscus.
Pathology
It is suggested to be due to disruption of the meniscotibial ligaments, or as a result of a tear of the peripheral attachment of the posterior horn of the medial meniscus 2.
Radiographic features
On MRI, it appears as an abnormal signal at the peripheral most portion of the posterior horn medial meniscus.
