Core Tip

Core Tip: Discoid medial meniscus is very rare, and the bilateral discoid medial meniscus is extremely rare. We present the case of a 30-year-old female with features of a meniscal tear in two symptomatic knees and radiographic findings of discoid menisci in both knees. A provisional diagnosis of bilateral discoid medial menisci was made. Magnetic resonance imaging confirmed the discoid nature of the medial menisci in both knees. Both knees underwent partial meniscectomy and menisci reformation by arthroscopy. After 6 mo of follow-up, the patient had good clinical and functional outcomes.
