Abstract
The discoid meniscus is an infrequent anatomical variant, which usually affects the lateral compartment of the knee. Its estimated prevalence is low and the higher rates have been observed in the Asian population. However, its actual frequency may be superior as has been described in various cadaveric studies. The most frequent clinical presentation is pain in the lateral knee compartment, and in only some cases is the classical snapping knee syndrome exhibited. The augmented thickness of the discoid menisci as well as its altered ultrastructure makes it more prone to tearing. Saucerization has been the classical surgical treatment. However, meniscal repair is preferred in children, particularly in the hypermobile Wrisberg type, when feasible. The long-term clinical results are good but signs of degenerative joint disease are frequently seen. Therefore, relative to meniscal removal, a conservative policy seems to be the most adequate option.
