Abstract

Case: A 4-year-old girl with no relevant medical history presented with left knee swelling. Knee laxity, magnetic resonance imaging findings of anterior cruciate ligament (ACL) deficiency and discoid meniscus, and the chronicity of symptoms prompted arthroscopic ACL reconstruction and meniscal saucerization. Pain and swelling continued, and repeat arthroscopy revealed regeneration of the discoid meniscus at 18-month follow-up. Conclusion: In this unusual case, a discoid lateral meniscus regenerated after saucerization. Regeneration could be attributed to the robust vascularity of the meniscus in pediatric patients. Surgeons should counsel about the risk of recurrence after treatment of discoid meniscus.
