PURPOSE: To estimate the adequate residual midbody meniscal width immediately after surgery saucerization with repair for discoid lateral meniscus (DLM) and at subsequent follow-up, and to evaluate the complication rate. METHODS: A retrospective analysis was conducted on complete DLM cases that underwent saucerization with repair from August 2017 to January 2023, with a minimum follow-up of 2 years. Knees were classified into 3 groups based on midbody meniscal width immediately after surgery: large (>13 mm), normal (9 to ≤13 mm), and small (50% reduction in residual midbody width, with a cutoff value of 11.5 mm. CONCLUSIONS: Although clinical outcomes showed favorable minimum clinically important difference achievement regardless of meniscus size, a residual midbody meniscal width >13 mm immediately after surgery decreased faster than smaller widths and had greater complication rate in DLM treated with saucerization and repair. LEVEL OF EVIDENCE: Level IV, retrospective case series.
