A 27-year-old man presented with intermittent right knee pain for 1 year with no previous trauma. Physical examination revealed only tenderness over the patella. Typical fluid-fluid levels were visible on magnetic resonance imaging (MRI), which highly suggested aneurysmal bone cyst (ABC) of the patella. After removal of a large window of thin cortical bone, curettage and bone grafting followed by cerclage wiring was performed. Histology confirmed the initial diagnosis of primary ABC of the patella. At the final follow-up visit at 71 months after surgery, the patient had normal joint activity with no pain or evidence of recurrence. Previous publications indicated patellectomy in the initial series, but curettage and bone grafting have more recently provided excellent results and good graft incorporation in most cases, even for aggressive lesions. In our patient, thorough curettage and bone grafting through a wide cortical window followed by cerclage wiring fixation and figure-eight sutures was a successful treatment option for primary ABC of the patella without articular disruption.
一名27岁男性，无既往外伤史，右膝关节间歇性疼痛1年。体格检查仅发现髌骨压痛。磁共振成像（MRI）可见典型的液-液平面，高度提示髌骨骨囊肿（ABC）。切除一大块薄皮质骨窗口后，进行刮除、植骨，随后行环扎钢丝固定。组织学检查证实最初诊断为原发性髌骨ABC。术后71个月的最后一次随访时，患者关节活动正常，无疼痛或复发迹象。既往文献表明，最初的治疗方法是髌骨切除术，但最近刮除和植骨在大多数情况下都取得了良好的效果，植骨融合良好，即使是侵袭性病变。在我们的患者中，通过宽大的皮质骨窗口进行彻底刮除和植骨，随后行环扎钢丝固定和8字缝合，是治疗无关节破坏的原发性髌骨ABC的成功选择。
