Introduction:
Introduction: Discoid medial meniscus is rare; bilateral involvement in adults is exceptionally uncommon.
Case Report:
A 52-year-old male presented with symptomatic right knee and asymptomatic left knee; magnetic resonance imaging (MRI) revealed bilateral discoid medial menisci (BDMM), with a complex tear involving the posterior horn on the right side. The right knee underwent arthroscopic saucerization of the central discoid element and partial medial meniscectomy of the posterior horn, followed by all-inside repair, whereas the left knee was managed conservatively. At the 12-month follow-up, clinical outcomes were excellent.
Conclusion:
Early MRI and individualized treatment strategies are critical in adult BDMM to optimize outcomes and preserve joint function.
