Aneurysmal bone cysts are uncommon lesions accounting for less than 1% of reported primary bone tumors. This case study reports the ninth primary aneurysmal bone cyst of the patella, and the second to be reported in a white male patient. The scarcity of reports in this vulnerable site may refute trauma as the cause. If the articular surface is spared, this lesion can be treated successfully by curettage and bone grafting, once a definitive diagnosis is made.
骨动脉瘤样囊肿是罕见病变，占所报道的原发性骨肿瘤不到1%。本病例报告了第九例髌骨原发性骨动脉瘤样囊肿，也是第二例报道的白人男性患者。该易患部位报告较少，可能反驳创伤是病因这一观点。一旦确诊，如果关节面未受累，该病变可通过刮除术和植骨术成功治疗。
