abstract: A 20-year-old man presented to our clinic with pain and swelling in the right knee of one year's duration. Biopsy of the patella revealed an aneurysmal bone cyst secondary to a giant cell tumor. He was treated by curettage and bone cement to fill the defect. The rarity of this lesion in the patella and its treatment modalities are discussed.
