A Case of Complete Discoid Medial Menisci in the Bilateral Knees

Abstract

We report a case of complete discoid medial menisci in the bilateral knees. A 13-year-old boy complained of pain in his right knee without any history of injury for a year. Physical examination revealed medial joint-line tenderness and click of the McMurray maneuver. Radiograph views showed no specific abnormalities. T2-weighted magnetic resonance imaging (MRI) of both knees revealed bilateral medial discoid menisci with high intensity area in the form of horizontal tears. Arthroscopic surgery was performed in his right knee and the same tears as MRI were seen. He achieved complete recovery after three months and returned to previous sports activity after seven months.
