Symptomatic bilateral medial discoid meniscus treated with arthroscopic meniscal remodeling: clinical case.

Medial discoid meniscus is a rare entity with a reported incidence of 0.12 to 0.3%, although the real incidence may be greater because not all the patients are symptomatic. Like lateral discoid menisci, medial discoid menisci are prone to degeneration that may prompt the presence of mechanical symptoms at early age. We present the case of a 14 year old male patient with bilateral knee symptoms of insidious onset without a traumatic event. Magnetic resonance revealed bilateral medial discoid menisci. Arthroscopic medial meniscus remodelling was performed in the right knee and, three months later, in the left knee, due to limitating mechanical symptoms. At the latest follow up -6 months for the right knee, 3 months for the left knee-, the patient resumed his sports activities.
