Abstract

Background

Total ankle arthroplasty (TAA) has been developed as treatment for disabling tibiotalar osteoarthritis. TAAs are divided into mobile- and fixed-bearings. The aim was to determine the incidence and trends of fixed- and mobile bearings over time and investigate the association of bearing type and risk of revision after primary TAA in the Netherlands.

Methods

Using data from the Dutch Arthroplasty Register (LROI) (2014–2023), we analyzed trends in use of bearing type, reasons for revision and implant survival (n = 1246).

Results

Fixed bearings were more often used than mobile bearings (67 % versus 33 %). Revision risk at 3, 5 and 7 years was respectively 2.8 %, 3.3 %, and 5.4 % for fixed bearings, versus 6.5 %, 10.4 %, and 11.3 % for mobile bearings. The adjusted hazard ratio was 2.5 (95 %CI 1.4–4.4) for mobile bearings.

Conclusion

Fixed bearings were associated with a lower revision risk than mobile bearings in total ankle arthroplasties based on Dutch registry data.

固定式全踝关节置换术与活动式全踝关节置换术相比，翻修风险更低：荷兰1246例患者的登记评估。

背景：全踝关节置换术（TAA）已发展成为治疗致残性胫跖骨关节炎。taa分为移动和固定轴承。目的是确定固定和移动轴承的发病率和趋势随着时间的推移，并调查轴承类型与荷兰原发性TAA后翻修风险的关系。方法：使用荷兰关节置换术登记（LROI）（2014-2023）的数据，我们分析了使用轴承类型、翻修原因和种植体存活的趋势（ = 1246）。结果：固定轴承比移动轴承更常使用（67 %对33 %）。固定轴承3年、5年和7年的修正风险分别为2.8 %、3.3 %和5.4 %，而移动轴承的修正风险分别为6.5 %、10.4 %和11.3 %。移动轴承调整后的风险比为2.5（95 %CI 1.4-4.4）。结论：根据荷兰注册数据，在全踝关节置换术中，固定轴承的翻修风险低于活动轴承。证据水平：II。

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.
