Discoid lateral meniscus of the knee-joint (questions of classification and diagnostics)

Abstract

In this article is analysed MRI of knee-joints of 409 patients and results of 15 knee joint arthroscopic revisions of patients with a discoid lateral meniscus. Considered a few classifications of discoid lateral meniscus types. Based on the possibilities of MRI and arthroscopy in detecting of discoid lateral meniscus abnormalities, taking into account the correlation these researches’ results there was highlighted Watanabe classification as the main for discoid lateral meniscus description as at MRI so at during arthroscopy. The third type of discoid lateral meniscus in Watanabe classification is selected as most clinically significant, while it is most hardness differentiated on MRI, that requires further scientific research.
