Classification is based on the degree of peripheral attachments to the tibia plateau, and the shape of the meniscus itself: complete vs incomplete. stable vs unstable stable: normal peripheral attachments with an intact posterior meniscofemoral ligament. watanabe classification of discoid lateral meniscus ( A C ) Watanabe classification of discoid lateral meniscus. ( From Kramer DE, Micheli LJ. Meniscal tears and discoid meniscus in children: diagnosis and treatment.

Every knee has a medial and lateral meniscus which are Cshaped pieces of fibrocartilage that absorb stress and act as cushions between the bones at the knee. At birth, the meniscus is not Cshaped, but discoid (round like a discus). With growth and walking, the discoid meniscus evolves into its watanabe classification of discoid lateral meniscus

Discussion. Discoid lateral meniscus is traditionally classified as one of 3 types based on those described by Watanabe et al. 11 The complete type refers to complete meniscal coverage of the tibial plateau, while the incomplete type covers 80 of the tibial plateau. The Wrisberg ligament type refers to a more normal morphology, Watanabe et al. classified various types of lateral discoid meniscus based on its arthroscopic appearance. Discoid menisci with normal peripheral attachments were labeled as either type I (complete) or type II (incomplete) according to the degree of coverage of the lateral tibial plateau.
