The objective of this case report was to evaluate meniscal suturing for a young patient with a chronic radial tear of the incomplete discoid lateral meniscus. The patient underwent saucerization in conjunction with repair of the displaced radial tear of the discoid meniscus. Six-months after surgery, arthroscopic examination showed the repaired meniscus to be healed well with good continuity. Repair of radial tears, even chronic tears, should be considered for young patients with torn discoid lateral menisci.
