Abstract

Falls are now the leading cause of injury-related deaths in the US among older adults. While foot/ankle pain, osteoarthritis and limited ankle joint range of motion serve as independent risk factors for falls in older adults, it is uncertain whether surgical correction of ankle osteoarthritis via total ankle arthroplasty (TAA) can mitigate this risk. In this retrospective cohort study, we examined US adults aged 50 and over who underwent TAA from January 2010 to April 2022 using commercial, state, and federal claims data obtained via PearlDiver, Inc. The surgery group was compared to a similar sample of older adults who were treated nonoperatively for foot and ankle osteoarthritis over the same time frame. Cox proportional hazards regression models were utilized to examine the association of surgery and an injurious fall while controlling for important covariates. In the first year of follow-up, a greater proportion of people fell in the non-surgery group (31%, 41,049/130,318) than in the surgery group (27%, 177/664) (chi-square p
