Intraarticular Ganglion Between the Cruciate Ligaments of the Knee

Abstract

Intraarticular ganglion cysts arising from the cruciate ligaments are rare. Only 9 cases have been described in the literature (2, 4–6, 8–10, 13, 14). Only in one case was the diagnosis suggested before operation by the appearance on MR imaging (4). We report a case of a patient presenting with a bone erosion in the proximal tibial epiphysis caused by an intraarticular ganglion cyst arising from the anterior cruciate ligament.
