Ganglion cysts of the cruciate ligaments: a series of 31 cases and review of the literature.

ABSTRACT

BACKGROUND: A case series for ganglion cyst of the cruciate ligament with MRI findings, clinical presentation, and management options along with review of literature is presented. METHODS: Of 8663 consecutive patients referred for knee MR imaging, 31 were diagnosed with ganglion cysts of the cruciate ligaments, including 21 men and 10 women of ages 12 to 73 years (mean 37). A review of charts revealed that knee pain was the chief complaint in all cases. Arthroscopic debridement of ganglion cyst was performed in 11 patients. RESULTS: MRI proved to be a valuable tool in diagnosing and deciding management of these cases. All 11 patients who underwent arthroscopic treatment were symptom-free on a minimum follow-of one year. CONCLUSION: Cyst formation associated with cruciate ligament of the knee is an infrequent cause of knee pain. MR imaging was important in confirming the cyst lesions and provided useful information prior to arthroscopy. Arthroscopic debridement of ganglion cyst produced excellent outcome without recurrence. This study describes the pertinent MRI and intraoperative findings of ganglion cyst.
