Case of a 2-staged revision surgical technique for the treatment of an aseptic total ankle arthroplasty (TAA) loosening: first surgery: removal of the loosened and painful TAA Scandinavian Total Ankle Replacement, with exclusion of infection, and reconstruction of the large bone defect (bone-defect downsizing surgery); proof of successful ankle bone reconstruction by CT-scan imaging; second surgery: implantation of a primary VANTAGE TAA (ankle reconstruction with new primary TAA).
The present case shows the management of a failed TAA with bone defect by performing a 2-step surgical approach: removal of loosened TAA with simultaneous bone stock restoration and then implantation of a new primary TAA. This concept is a possible alternative to a post-TAA ankle arthrodesis or to the use of a TAA revision system.
采用两阶段翻修手术技术治疗无菌性全踝关节置换术（TAA）松动的病例：第一次手术：去除松动和疼痛的 TAA 斯堪的纳维亚全踝关节置换术，排除感染，并重建大骨缺损（骨缺损缩小手术）；通过 CT 扫描成像证明踝关节骨重建成功；第二次手术：植入原发性 VANTAGE TAA（新型原发性 TAA 踝关节重建）。
本病例通过两步骤手术方法成功治疗了 TAA 骨缺损伴失败的病例：去除松动的 TAA，同时恢复骨量，然后植入新型原发性 TAA。该概念是 TAA 踝关节融合术或 TAA 翻修系统的替代方案。
