Abstract
BackgroundTotal ankle arthroplasty (TAA) offers an effective option for end-stage osteoarthritis. The incidence and preoperative risk factors for early adverse events (AEs) following primary and revision TAA may be useful information for providers. MethodsA large database was queried from 2010 to 2016 to identify 905 patients of whom 818 underwent primary TAA (90.4%) and 87 underwent revision TAA (9.6%). Data on patient demographics, comorbidities, and hospital length of stay were analyzed as risk factors for reported 30-day AEs. ResultsThe overall AE rate was 5.5% (50/905) for the entire cohort. AEs occurred more frequently for revision TAA (9/87) than primary TAA (41/818) cases (OR 2.43, p=0.022). Age (OR 1.03, p=0.045), BMI (OR 1.04, p=0.046), and revision TAA (OR 2.56, p=0.002) were independent risk factors for 30-day AEs in multivariate analysis. ConclusionsOlder age, higher BMI, and revision cases are associated with a higher risk of AEs.
