Discoid medial meniscus is a rare finding. We report a case of bilateral discoid medial menisci. A 24-year-old student had a 7-year history of both knees complaints with no specific acute injury. There were 10° extension lags in both knees and the radiographs showed widening of the medial joint space. Magnetic resonance imaging revealed bilateral complete type discoid medial menisci with horizontal tears. His right knee was treated successfully by the excision of the torn central anomalous discoid portion of the meniscus using the arthroscopic technique.
