Bursitis: Sounds like accumulation of fluid in a bursa -- eg the semimembranous bursa - http://orthoanswer.org/knee-leg/knee-bursitis/definition.html - See your pediatrician for further evaluation.

Evaluation: Swelling behind the knee suggests a popliteal or Baker's cyst. This is uncommon in children but warrants evaluation.
