Meniscal injury is uncommon in young people.
In adolescents, they are often subsequent to trauma and associated with other ligamentous injuries. In children, they are frequently isolated and due to a congenitally abnormal meniscus, such as a discoid meniscus. I fibres arranged circumferentially, with a few radial, oblique and vertical fibres. Menisci translate 2-10mm with flexion and extension of the knee to optimize contact between the femur and tibia. The meniscus also assists with knee stability, and contributes to the nutrition of articular cartilage by enhancing synovial fluid distribution.
