Arthroscopic Saucerization of Discoid Lateral Meniscus, With Meniscus Repair as Indicated, Results in Excellent Outcomes in Pediatric Patients Younger Than 12 Years of Age

PurposeThe purpose of our study was aimed to evaluate the experiences and outcomes of arthroscopic partial meniscectomy in symptomatic non-Wrisberg discoid lateral meniscus in children under 12 years old at a single center.MethodsWe retrospectively reviewed the medical records of all pediatric patients who were treated for non-Wrisberg discoid meniscus at our institute between 2013 and 2021. Patients were separated into two groups: Patients who underwent partial resection with saucerization (group A) or patients who underwent saucerization, tear repair and fixation (group B). Clinical outcomes were compared between the two groups.ResultsA total of 20 patients (22 knees) were treated for non-Wrisberg discoid meniscus and included in this study. Nine patients underwent partial resection with saucerization (group A) while 11 patients underwent saucerization, tear repair and fixation (group B). The average follow-up was 3 years (range 2-10 years). The results showed that 17 of the 20 patients had excellent outcomes while the other 3 had good outcomes after a minimum follow-up of 2 years. The average KOOS-Child score was 93.ConclusionArthroscopic saucerization of symptomatic non-Wrisberg discoid lateral meniscus, with additional repair as indicated, results in excellent or good outcomes in children less than 12 years of age.
