Symptomatic Posterior Cruciate Ligament Ganglion Cyst in a Child with Hemophilia

A Case Report

Abstract

Case: 

We report the case of an active 8-year-old boy with a history of hemophilia and with a 1-year history of knee pain and limited range of motion. Magnetic resonance imaging of the knee demonstrated a ganglion cyst arising from the posterior cruciate ligament (PCL). Arthroscopic decompression of the cyst was performed, and he was asymptomatic at the 1-year follow-up.

Conclusion: 

This case demonstrates a rare finding of a pediatric PCL ganglion cyst. We suggest that clinicians should be aware of this as a cause of knee pain in the pediatric population and that arthroscopic management can be successful.
