N2 - 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.
