Anomalies associated with a discoid medial meniscus have been described. However, the clinical relevance of these anomalies has not been previously reported. Therefore, we report the clinical relevance of some of these anomalies based on our experience with a 21-year-old soldier with a 3-month history of medial right knee pain. Magnetic resonance imaging (MRI) revealed bilateral discoid medial menisci, cupping of the medial tibial plateau, and an abnormal anteroinferior transposition of the anterior horn of the meniscus. Partial meniscectomy was performed in the usual manner and the meniscus reshaped, including its anteromedial corner.
