How does mortality risk change over time after hip and knee arthroplasty?

Abstract

BackgroundMortality after THA and TKA is lower than expected for several years after surgery when compared with age- A nd sex-adjusted population data. With long-term followup (beyond approximately 10 years), some evidence has suggested that this trend reverses, such that postsurgical mortality is higher than expected as more time passes. However, the degree to which this may be the case has not been clearly established.Questions/purposesIn this large-registry study, we asked: What is the long-term mortality after THA and TKA compared with the expected mortality, adjusted for age, sex, and calendar year.MethodsUsing data on 243,057 THAs and 363,355 TKAs performed for osteoarthritis from the ..
