Abstract 

A 13-year-old male with a previous one-month history of a ‘locking’ painful knee underwent an MR investigation of his knee. The MR findings showed a discoid meniscus with a meniscal tear, which at arthroscopy proved to be an unusual Wrisberg III variant. The morphology of discoid meniscus is defined including the Wrisberg III variant. The MR factors are discussed including optimum planes and sequences used by MRI to investigate meniscal pathologies including tears. The treatment regimes are investigated including surgical options.

Keywords: Discoid meniscus, Magnetic resonance knee, MR scanning parameters, Knee protocols, Congenital variants of the knee
