Symptomatic Posterior Cruciate Ganglion Cyst Causing Impingement between Posterior Root of the Medial Meniscus and Anterior to the Posterior Cruciate Ligament

摘要

There are several reports of symptomatic ganglion cysts near the posterior cruciate ligament (PCL), but no reports of a symptomatic ganglion originating from the anterior aspect of the PCL in the deep recess between the posterior root of the medial meniscus and the PCL, bulging into the posteromedial joint space. In this report, we present the clinical features of a patient with a symptomatic ganglion cyst treated successfully by arthroscopic excision.
