Bilateral complete discoid medial meniscus: a case report.

Discoid medial meniscus is very rare, and bilateral discoid medial meniscus is extremely rare. We report a case of bilateral discoid medial meniscus. The patient had symptoms in the right knee but was asymptomatic in the left knee. We performed magnetic resonance imaging for both knees. The patient was treated by saucerization and by all inside repair of the anterior horn tear in the right knee. We performed second-look arthroscopy after 18 months.
