Primary aneurysmal bone cyst of the patella: A case report

SummaryAn aneurysmal bone cyst is rare in the patella. We report the case of a 28-year-old woman who presented with chronic pain and no previous trauma history. Treatment included curettage of the cyst and filling with a corticocancellous graft. Thirty-one months after surgery, the knee was mobile and painless and graft incorporation was good.
