Review the meniscus anatomy, pathology and common findings during MRI study.

The meniscus function to absorb shock, distribute axial load, assist in joint lubrication, and facilitate nutrient distribution. The medial meniscus (MM) and lateral meniscus LM are wedge-shaped, semilunar, brocartilaginous structures.

MR imaging in lateral and medial meniscus (LM/MM) studies still has many limitations, namely - Detection of small posterior horn tears - Tears that involve less than one-third of the LM. It also has an high false-positive rate has been reported for longitudinal tears of the MM posterior horn, possibly secondary to incomplete visualization of the far periphery of the MM at arthroscopy or to spontaneous healing (1,2).

The meniscus appearance in MRI (pathologic or not) is a mandatory knowledge even for the general radiologist.
