This is a pilot study reviewing patients undergoing ankle replacement with the 3-D printed INFINITY™ with ADAPTIS™ total ankle arthroplasty (TAA) system.
A retrospective review was conducted of patients with a minimum two-year follow-up who underwent TAA with the INFINITY™ with ADAPTIS™ implant system. Outcome measures include implant survivorship, complications with subsequent reoperations, patient reported outcomes, and radiologic subsidence or radiolucency.
Thirty patients were included with median follow-up of 26 months (range, 24-36). Implant survival rate was 90% (27/30). Two patients experienced linear radiolucency > 2 mm: one required a revision TAA secondary to tibial subsidence; the other patient was asymptomatic and nonprogressive on serial radiographs. No cystic radiolucencies > 5 mm were identified. VAS, PROMIS PF, and FADI scores improved significantly.
TAA performed with the 3-D printed INFINITY™ with ADAPTIS™ implant technology led to ninety percent short term implant survivorship and improvement in patient reported outcomes with comparable results to other 4th generation arthroplasty systems as a treatment modality for end-stage ankle arthritis.

这是一项对接受 3D 打印 INFINITY™与 ADAPTIS™全踝关节置换术（TAA）系统的踝关节置换患者进行的初步研究。
对接受 INFINITY™与 ADAPTIS™植入系统的 TAA 治疗且随访时间至少 2 年的患者进行回顾性研究。评估指标包括植入物存活率、后续翻修手术的并发症、患者报告的结果以及影像学下沉或透亮线。
共纳入 30 例患者，中位随访时间为 26 个月（范围 24-36 个月）。植入物存活率为 90%（27/30）。2 例患者出现线性透亮线>2mm：1 例因胫骨下沉需要进行翻修 TAA；另 1 例患者无症状且连续影像学检查未见进展。未发现>5mm 的囊性透亮线。VAS、PROMIS PF 和 FADI 评分显著改善。
使用 3D 打印 INFINITY™与 ADAPTIS™植入技术进行 TAA 治疗，短期植入物存活率为 90%，患者报告的结果得到改善，与其他第四代关节置换系统的结果相当，是治疗终末期踝关节关节炎的一种有效方法。
