We retrospectively reviewed the results for seven patients who were less than twelve years old with eight discoid lateral menisci. The average age at the time of operation was 8.1 years, and the average duration of follow-up was 9.3 months. The state of meniscus and cartilage was evaluated with Watanabe's classification and Fujisawa's classification. The clinical results were rated according to the Japanese Orthopedic Association (JOA) Score for Meniscus Injuries. The mechanism of injury was not clear in all cases. The diagnosis of complete lateral discoid meniscus was confirmed in seven cases (88%) and the degeneration of cartilage was slight. Subtotal meniscectomy was required in the complete type (seven cases) due to prevalence of horizontal tear and hypermobility. The average JOA score at initial presentation was 50 points, and it remarkably improved to an average of 96 points at postoperative recent follow-up examination.
