Discoid meniscus.
The discoid meniscus is probably a congenital deviation that usually occurs laterally. The Watanabe classification consists of complete, incomplete, or Wrisburg ligament types. Complete and incomplete discoid menisci normally require treatment only when a tear occurs. The Wrisburg ligament type lacks a posterior capsular attachment. The preferred treatment is repair of the posterior capsular disruption with saucerization of the remaining meniscus.
