How Does Mortality Risk Change Over Time After Hip and Knee Arthroplasty?

摘要

Background Mortality after THA and TKA is lower than expected for several years after surgery when compared with age-and 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.
