Aneurysmal bone cysts account for less than 1% of primary bone tumours and have a predilection for the metaphyses of the long bones of the leg. Only 1% of all aneurysmal bone cysts occur in the patella. We report on a 30-year-old man with a primary aneurysmal bone cyst in the right patella treated with curettage. The defect was filled with demineralised bone matrix and allogeneic cancellous bone graft. At the 1.5-year follow-up, the bone graft was well incorporated, the patient experienced no pain or tenderness and had a full range of knee movement.
骨动脉瘤样囊肿占原发性骨肿瘤的比例不到1%，好发于下肢长骨的干骺端。所有骨动脉瘤样囊肿中仅有1%发生于髌骨。我们报告1例30岁男性，其右髌骨原发性骨动脉瘤样囊肿接受了刮除术治疗。骨缺损处填充了脱矿骨基质和同种异体松质骨移植骨。在1.5年的随访中，移植骨融合良好，患者无疼痛或压痛，膝关节活动范围正常。
