title: Surgical treatment of symptomatic discoid medial meniscus in childhood:  a case report.
abstract: If the meniscus has a spherical shape and not a semilunary structure, it is called as discoid meniscus. This anomaly is generally seen in the lateral meniscus; however, it is rare in the medial meniscus. Although the discoid meniscus is usually asymptomatic in children and adolescents, it could present as a meniscal tear. An 11-year-old boy was admitted to our hospital with right knee pain and lack of extension of the knee joint. He was diagnosed as discoid medial meniscus. On physical examination, we observed tenderness at the knee joint line with an effusion of the knee and a restriction during the extension movement of the knee joint. McMurray test was positive. Conventional radiograms revealed widening of the medial joint line and cupping of the medial tibial plateau. Magnetic resonance imaging indicated a discoid meniscus image at sagittal slices. In this case, after the arthroscopic partial menisectomy, we obtained an excellent result at 2 years follow-up.
