Abstract

|
|
|
Although the lateral discoid meniscus has been observed frequently, the medial discoid meniscus is an extremely rare anomaly. The incidence of lateral discoid menisci ranges from 1.4% to 15.5% and the incidence of medial discoid menisci ranges from 0.06% to 0.3%. We present 1 patient of bilateral medial discoid menisci with tear on left side and 1 patient of unilateral medial discoid meniscus with tear, that were diagnosed by magnetic resonance imaging (MRI) and arthroscopy. We performed partial meniscectomy on 2 cases of symptomatic medial discoid menisci under arthroscopy and meniscus-related symptoms were relieved. We report 3 cases of 2 patients with medial discoid meniscus.
