Ganglion cyst of the Hoffa′s fat pad of the knee joint

Abstract

We report a rare case of ganglion cyst of Hoffa's fat pad of knee joint. These lesions are asymptomatic in most cases and are often misdiagnosed as meniscal or ligamentous lesions of the knee joint. The final diagnosis was done with magnetic resonance imaging (MRI) of the knee joint, and the lesion was treated with surgery. It was not possible to resect the lesion through arthroscope, so open resection and complete excision of the cyst was done.
