Abstract: Meniscus injury is usually less common in children than in adults. However, with the increase of the number and intensity of physical exercise in children, the frequency of meniscus injury in this group is gradually increasing. At present, the diagnosis and treatment of adult meniscus tear have been well studied, while the repair of children's meniscus injury has also made some progress, but there is no consensus on the repair of meniscus injury in children. This study referred to domestic and foreign literature on meniscus injury treatment in children in recent years and reviewed the research progress in meniscus vascular distribution, classification, injury mechanism, and repair methods, hoping to provide a reference for the repair of meniscus injury in children.
