Arthroscopic Saucerization and Repair of a Torn Medial Discoid Meniscus.

A discoid meniscus is a congenital abnormality that usually affects the lateral meniscus, leading to instability and increased risk of tearing. A discoid medial meniscus is an extremely rare pathology that is seldom described in literature. In this report, we present the technique of operative treatment of a symptomatic, torn discoid medial meniscus. The meniscus is saucerized to 6-8 mm of stable rim, and the inside-out technique is used as the modality of meniscal fixation. Although a discoid medial meniscus is an uncommon finding, all treating surgeons should be aware of the possibility during surgical intervention.
