We present the case of a 37-year-old man with features of a meniscal tear in 1 symptomatic knee 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. The symptomatic knee was managed with good results by partial meniscectomy using a routine arthroscopic procedure.Conclusion:
Discoid medial meniscus is a relatively rare pathology of the knee joint, and bilateral cases are extremely rare. A high index of suspicion is necessary for diagnosis; only symptomatic knees should be treated surgically.
