Description
Summary:Introduction Contemporary studies evaluating utilization and trends of total ankle arthroplasty (TAA) and ankle fusion (AF) for tibiotalar osteoarthritis are sparse. Therefore, the purpose of this study was to utilize a nationwide administrative claims database from 2010 to 2019 to compare: (1) baseline demographics; (2) utilization, (3) in-hospital length of stay (LOS), and (4) costs of care. Methods Using the PearlDiver database, a retrospective query from January 1st, 2010 to December 31st, 2019 was performed for all patients who underwent TAA and AF for tibiotalar osteoarthritis. Baseline demographics, comorbidities, and geographic utilization were compared using Pearson Chi-square analyses. Linear regression was used to compare differences in procedure utilization and in-hospital LOS during the study interval. Reimbursements between the two cohorts during the study interval were compared. A p value less than 0.05 was statistically significant. Results In total, 14,248 patients underwent primary TAA ( n  = 5544) or AF ( n  = 8704). Patients undergoing AF were generally younger (
