Abstract：
BACKGROUND: Launched in 2018 for revision total ankle arthroplasty (rTAA), the INVISION talar component addresses subsidence when poor talar bone stock is present. Due to the recency of the market-availability of the INVISION, studies evaluating its efficacy are lacking. This study presents the first analysis of early-term outcomes of patients undergoing rTAA with the INVISION talar component.
METHODS: This was a single-center, retrospective review of 28 patients undergoing rTAA with the INVISION talar component and INBONE II tibial component performed between 2018 and 2022. Data on preoperative characteristics, postoperative complications, secondary procedures, and survivorship were collected. The primary outcome measures were rates of major complications, re-operation, and implant failure. Secondary outcomes included post-operative changes in varus and valgus alignment of the tibia and talus.
RESULTS: The most common secondary procedures performed with rTAA were medial malleolus fixation (n = 22, 78.6%) and gastrocnemius recession (n = 14, 50%). Overall, 10.7% (n = 3) of patients underwent reoperation and 14.3% (n = 4) suffered major complications. Incidence of implant failure was 10.7% (n = 3). All reoperations were caused by infection. Mean varus alignment of the tibia and talus improved from 4.07 degrees and 4.83 degrees to 1.67 degrees and 1.23 degrees, respectively. Mean valgus alignment of the tibia and talus improved from 3.67 degrees and 4.22 degrees to 2.00 degrees and 2.32 degrees, respectively.
CONCLUSIONS: In a series of 28 patients undergoing rTAA with the INVISION talar component, we discovered comparatively low rates of reoperation, major complication, and implant failure (10.7%, 14.3%, and 10.7%). The INVISION system appears to have a reasonable safety profile, but further studies evaluating long-term outcomes are required to assess the efficacy of the INVISION system.

摘要：
背景：2018年推出的翻修全踝关节置换术（rTAA），INVISION距骨组件可解决距骨储备不足时的沉降。由于最近的市场可用性的INVISION，缺乏评估其疗效的研究。这项研究首次分析了接受具有INVISION距骨成分的rTAA患者的早期结局。
方法：这是一个单中心，对2018年至2022年期间接受INVISION距骨组件和INBONEII胫骨组件rTAA的28例患者进行回顾性分析.术前特征数据，术后并发症,次要程序,并收集了幸存者。主要结果指标是主要并发症的发生率，重新操作,和植入物失败。次要结果包括胫骨和距骨的内翻和外翻对齐的术后变化。
结果：使用rTAA进行的最常见的二次手术是内踝固定（n=22，78.6％）和腓肠肌后退（n=14，50％）。总的来说,10.7％（n=3）的患者接受了再次手术，14.3％（n=4）的患者出现了重大并发症。植入失败的发生率为10.7%(n=3)。所有再次手术均由感染引起。胫骨和距骨的平均内翻对准从4.07度和4.83度改善到1.67度和1.23度，分别。胫骨和距骨的平均外翻对齐从3.67度和4.22度改善到2.00度和2.32度，分别。
结论：在一系列28例接受具有INVISION距骨成分的rTAA的患者中，我们发现再手术率相对较低，主要并发症,和植入物失败(10.7%，14.3%,和10.7%）。INVISION系统似乎具有合理的安全性，但评估长期结局的进一步研究需要评估INVISION系统的疗效.
