Chondroblastoma is a rare bone tumor that originates from the epiphysis, constitutes around 1% of all primary bone tumors and is recognized for its tendency to exhibit local invasiveness, as well as the possibility of metastasis and recurrence in nearby areas. Currently, the main surgical treatment for chondroblastoma is open surgery, involving excision of the lesion. There are relatively few reports on arthroscopic surgery for the treatment of chondroblastoma. However, open surgical curettage is associated with operation-related trauma and potential for damage to the osteoepiphysis resulting in growth disturbances.
This case study presents the application of an arthroscopic technique in a 14-year-old male patient with chondroblastoma affecting the proximal tibia and tibial eminence. The procedure involved thorough removal of the lesion using direct visualization with the management of the cavity utilizing a substitute for autologous bone graft. After 1 year of follow-up, the patient remains free from symptoms, exhibits normal knee functionality, and radiographic analysis reveals a good autologous bone graft fusion without any signs of recurrence.
Based on the existing cases of arthroscopic treatment for chondroblastoma and the report of this case, arthroscopic treatment for chondroblastoma can be considered as a specific treatment option for certain patients. In some cases, this technique could be an effective alternative to open surgery.
软骨母细胞瘤是一种罕见的骨肿瘤，起源于骨骺，约占所有原发性骨肿瘤的1%，以其局部侵袭倾向以及在附近区域转移和复发的可能性而闻名。目前，软骨母细胞瘤的主要手术治疗方法是开放手术，包括切除病变。关于关节镜手术治疗软骨母细胞瘤的报道相对较少。然而，开放手术刮除术与手术相关创伤以及损伤骨骺导致生长障碍的可能性有关。
本病例研究展示了关节镜技术在一名14岁男性软骨母细胞瘤患者中的应用，该患者的近端胫骨和胫骨结节受到影响。手术过程包括通过直接可视化彻底清除病变，并使用自体骨移植替代物处理骨腔。经过1年的随访，患者无症状，膝关节功能正常，影像学分析显示自体骨移植融合良好，无任何复发迹象。
基于现有的软骨母细胞瘤关节镜治疗病例以及本病例报告，关节镜治疗软骨母细胞瘤可被视为某些患者的一种特定治疗选择。在某些情况下，该技术可能是开放手术的有效替代方法。
