Item Discoid meniscus: current concepts(2020-07) Tuca, María; Saavedra, Manuel; Sepúlveda, Matías; Birrer, ÉstefaníaDiscoid meniscus is the most frequent congenital malformation of the menisci, and primarily affects the lateral meniscus; it is highly prevalent in the Asian population. The anatomic, vascular, and ultrastructural features of the discoid meniscus make it susceptible to complex tears. Discoid meniscus anomalies are described according to their shape; however, there is consensus that peripheral stability of the meniscus should also be defined. Initial workup includes plain X-rays and magnetic resonance imaging, while arthroscopic evaluation confirms shape and stability of the meniscus. Clinical presentation is highly variable, depending on shape, associated hypermobility, and concomitant meniscal tears. Treatment seeks to re-establish typical anatomy using saucerization, tear reparation, and stable fixation of the meniscus.
