Chondroblastoma, a rare benign bone tumour arising from the epiphysis, accounts for approximately 1% of all primary bone tumours and is known to be locally aggressive with potential for metastases and local recurrence. Open surgical curettage is associated with high risk of recurrence and potential for damage to the physis resulting in growth disturbances. We report a 14-year-old girl with chondroblastoma involving the distal femoral epiphysis in whom an arthroscopic approach was employed for thorough curettage of the lesion under direct vision followed by cavity management using bone graft substitute. At seven years follow-up she is asymptomatic, has normal knee function and her radiographs have shown good osteointegration of the synthetic graft with no evidence of recurrence. By combining the principles of intra-articular and endosteal arthroscopy in select patients, both tumour excision and cavity management can be done arthroscopically.
软骨母细胞瘤是一种起源于骨骺的罕见良性骨肿瘤，约占所有原发性骨肿瘤的1%，已知具有局部侵袭性，有转移和局部复发的可能。开放手术刮除术复发风险高，且有可能损伤骨骺导致生长障碍。我们报告一名14岁患有累及股骨远端骨骺软骨母细胞瘤的女孩，采用关节镜方法在直视下对病变进行彻底刮除，随后使用骨移植替代物处理骨腔。随访七年，她无症状，膝关节功能正常，X线片显示合成移植物骨整合良好，无复发迹象。通过在特定患者中结合关节内和骨内膜关节镜检查的原则，肿瘤切除和骨腔处理均可通过关节镜完成。
