Case. This case report describes the operative management of 16-year-old male with a symptomatic chondroblastoma of the distal femur with breach of the chondral surface. Following appropriate imaging and core needle biopsy, the diagnosis was confirmed histologically. The patient then underwent intralesional curettage and osteochondral allograft reconstruction of the defect. At one-year follow-up the patient was pain-free and has obtained excellent range of motion. There is radiographic evidence of allograft incorporation and no evidence of local recurrence. Conclusion. Osteochondral allograft reconstruction is an effective option following marginal resection and curettage of chondroblastoma involving the chondral surface of the distal femur.
病例。本病例报告描述了一名16岁男性股骨远端有症状的软骨母细胞瘤且软骨表面破裂的手术治疗情况。经过适当的影像学检查和粗针活检后，组织学确诊。患者随后接受了病损内刮除术和骨软骨异体移植重建缺损。在一年的随访中，患者无痛，活动范围极佳。有影像学证据表明异体移植已融合，且无局部复发迹象。结论。对于累及股骨远端软骨表面的软骨母细胞瘤，在进行边缘切除和刮除术后，骨软骨异体移植重建是一种有效的选择。
