Simultaneous bilateral ganglion cysts of the anterior cruciate ligaments

ABSTRACT

Intra-articular ganglion cysts of the anterior cruciate ligament (ACL) are rare, and bilateral ganglion cysts are even rarer. These cysts may cause intermittent or chronic nonspecific knee discomfort. Although three cases of bilateral ganglion cysts have been reported in the literature, the knees were not simultaneously affected in those cases. Herein, we report the case of a 56-year-old woman who presented with simultaneous bilateral ganglion cysts of the ACL that were symptomatic. She was successfully treated with arthroscopic resection and debridement. We also present a brief review of the literature, highlighting the aetiology, diagnosis and management of ganglion cysts of the ACL. To the best of our knowledge, this is the first report of simultaneous bilateral intra-articular ganglion cysts of the ACL.
