Arthroscopic Saucerization of a Symptomatic Posterior Horn Tear in a Discoid Medial Meniscus

Abstract

Background: Discoid medial meniscus is an extremely rare congenital anatomic variant with an estimated incidence of 0.12%. Arthroscopic meniscal saucerization and repair are reserved for symptomatic tears only. We present a case of discoid medial meniscus tear, outline the surgical arthroscopic technique used for treatment, and compare several surgical approaches. Case Report: An 18-year-old male presented with left knee pain and mechanical symptoms present for 2 years. Physical examination showed stability to both varus and valgus stresses with absence of locking or catching on McMurray testing. Magnetic resonance imaging confirmed discoid medial meniscus with a horizontal oblique tear of the posterior horn. The patient underwent saucerization of the left discoid medial meniscus and medial meniscus repair. Conclusion: Discoid medial meniscus predisposes individuals to meniscal tears that often require operative management. Careful consideration of surgical approach can help to optimize patient outcomes while minimizing the risk of iatrogenic injury.

Arthroscopic Saucerization and Repair of a Torn Medial Discoid Meniscus

“…describe treatment of a medial discoid meniscus tear in an 18-year-old male with saucerization and meniscus repair, reporting the patient was asymptomatic at 6 months and 1 year follow-ups and returned to full physical activity. 9 Jin et al. describe saucerization of a symptomatic discoid medial meniscus coalesced with the anterior cruciate ligament in a 29-year-old male, resulting in no symptoms and full return to physical activities at 12 months.…”
