Abstract

Background

This is a pilot study reviewing patients undergoing ankle replacement with the 3-D printed INFINITY™ with ADAPTIS™ total ankle arthroplasty (TAA) system.

Methods

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.

Results

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.

Conclusion

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.

3-D 打印多孔表面固定轴承全踝关节成形术的早期经验：至少两年的随访

这是一项试验性研究，对使用 3-D 打印 INFINITY™ with ADAPTIS™ 全踝关节置换术（TAA）系统进行踝关节置换的患者进行回顾性研究。该研究对使用 INFINITY™ with ADAPTIS™ 植入系统接受踝关节置换术的患者进行了至少两年的回顾性研究。结果指标包括植入物存活率、随后再次手术的并发症、患者报告的结果以及放射学沉降或放射透明。30 名患者的中位随访时间为 26 个月（24-36 个月）。植入物存活率为 90%（27/30）。有两名患者的线性放射影大于 2 毫米：其中一名患者因胫骨下陷而需要进行 TAA 翻修术；另一名患者无症状，连续拍片检查也无进展。没有发现直径大于 5 毫米的囊性放射性肿物。VAS、PROMIS PF和FADI评分明显改善。使用带有 ADAPTIS™ 植入物技术的 3-D 打印 INFINITY™ 进行 TAA 手术后，植入物的短期存活率达到 90%，患者报告的结果也有所改善，与其他 4 代关节成形系统作为治疗终末期踝关节炎的方法相比，效果相当。III级，回顾性队列研究，预后性

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
