Meniscal contusion refers to a form of meniscal injury where there is no overt tear or gross disruption. They usually occur from flexion injuries with compression of the posterior horn of the medial meniscus between the femoral condyle and the tibia.
Radiographic features
MRI
In the setting of trauma, they may be seen as areas of high T2 signal with features of edema. Often there is diffuse intrameniscal hyperintensity, which may mimic a fissure. Concomitant subchondral bone contusion may distinguish meniscal contusions from true fissures 2.
