Two patients with giant-cell tumors of the patella are presented in this report. Both patients were young females who were noted to have had nonspecific anterior knee pain and mild swelling of 1 to 12 months' duration prior to admission to our hospital. Local tenderness over the peripatellar area and slight limitation of full flexion were noted during physical examination. The radiographic presentation of each patella appeared as an expansile and lytic lesion with a thin cortex, without evidence of intra-articular involvement. Chest radiography and routine laboratory examination results were normal. After biopsy, intralesional curettage with phenol cauterization and allograft reconstruction was the preferred treatment in these two patients, with both tumors considered to be stage 2 according to Enneking's staging system. Following surgery, range of motion exercise was started after 6 weeks of immobilization with a long leg splint. Both patients regained full range of motion and were pain free. Radiographically, bone remodeling without evidence of recurrence was noted in both patients 2 years postoperatively.
本报告介绍了两名患有髌骨巨细胞瘤的患者。两名患者均为年轻女性，在入院前1至12个月均出现非特异性前膝疼痛和轻度肿胀。体格检查时发现髌周区域有局部压痛，且完全屈曲略有受限。每个髌骨的影像学表现均为具有薄皮质的膨胀性溶骨性病变，无关节内受累迹象。胸部X线检查和常规实验室检查结果均正常。活检后，这两名患者首选病灶内刮除加苯酚烧灼及同种异体骨重建治疗，根据Enneking分期系统，这两个肿瘤均被认为是2期。手术后，用长腿夹板固定6周后开始进行活动度锻炼。两名患者均恢复了完全活动度且无疼痛。影像学检查显示，术后2年两名患者均有骨重塑，无复发迹象。
