Lesions of the posterior horn of medial meniscus (PHMM) are very often associated with an ACL rupture (16,32,49). Certain specific lesions of the Medial Meniscus (MM) such as meniscosynovial or meniscocapsular tears and meniscotibial ligament lesions are associated with 9 to 17% of ACL Tears (8,21) and are seldom recognized on preoperative magnetic resonance imaging (MRI) scans (8,38). They also often remain undiagnosed when viewing from the standard anterior compartment arthroscopic portals including a probing. They were named in the 1980s by Strobel et al (42) as ‘‘Ramp’’ lesions of the meniscus and have drawn a lot of attention over the past few years (3,8,21,38,42). The aim of this article will be to write a narrative review of this Ramp meniscal lesion.
