Chondroblastoma is a rare benign tumor that affects the epiphysis of long bones in adolescents. Chondroblastoma located in the femoral head is associated with a higher recurrence rate and carries the additional risks of head collapse and degenerative hip disease. Aggressive curettage followed by bone grafting is the current mainstay of treatment. To our knowledge, the long-term postoperative outcome of this technique remains unknown due to the short follow-up of previous case reports. We present the case of a 17-year-old male who underwent fresh osteochondral allograft following curettage of a femoral head chondroblastoma, using a Ganz surgical hip dislocation. He made an uneventful recovery without tumor recurrence. The patient was followed up to 8 years postoperatively. However, there were clinical and radiographic degenerative changes at 6 years of follow-up.
软骨母细胞瘤是一种罕见的良性肿瘤，好发于青少年长骨的骨骺。位于股骨头的软骨母细胞瘤复发率较高，还存在股骨头塌陷和髋关节退行性疾病等额外风险。积极刮除后植骨是目前的主要治疗方法。据我们所知，由于既往病例报告的随访时间较短，该技术的长期术后结果尚不清楚。我们报告一例17岁男性患者，在采用Ganz手术髋关节脱位刮除股骨头软骨母细胞瘤后，接受了新鲜同种异体骨软骨移植。他恢复顺利，无肿瘤复发。对该患者进行了术后8年的随访。然而，在随访6年时出现了临床和影像学上的退行性改变。
