Abstract
Background:
As total ankle arthroplasty (TAA) rises in popularity nationwide, the incidence of revision TAA continues to increase. This study evaluates patient demographics, surgical techniques, complications, and implant survivorship following revision TAA.
Methods:
This was a single-center, retrospective review of revision TAAs performed between September 2007 and September 2022. Patients with a follow-up period of less than 1 year were excluded from the study. Demographic, surgical, and implant data were analyzed. Primary outcomes were prevalence of complications and implant failure.
Results:
Seventy-eight patients underwent a revision TAA. The mean age at revision was 64.2 years, with a follow-up of 4.5 years. Loosening (65.5%) was the primary indication, and both components were removed in 89.7% of cases. The most common implants for revision TAA were Inbone II (71.8%) and Inbone I (16.7%). Reoperation and rerevision rates were 37.2% and 21.8%, respectively, with infection being the leading cause. The 1- and 3-year implant survivorship rates were 94% and 88%, respectively.
Conclusion:
Revision TAA remains a viable salvage procedure but carries a moderate complication rate, highlighting the importance of careful patient selection, surgical planning, and long-term monitoring.
