title: Advanced age and comorbidity increase the risk for adverse events after revision total hip arthroplasty.
abstract: With the institution of quality-assurance parameters in health care, physicians must accurately measure and report the true baseline rates of adverse events (AEs) after complex surgical interventions. To better quantify the risk of AEs for revision total hip arthroplasty (THA), we divided a cohort of 306 patients (322 procedures) into age groups: group I (<65 years, n = 138), group II (65-79 years, n = 119), and group III (≥80 years, n = 65). Ninety-day rates of major AE were 9%, 19%, and 34% in the groups, respectively. Group III had an increased chance of experiencing major AE compared with groups I and II. Age and Charlson Comorbidity Index independently predicted major complications, whereas body mass index, sex, and type of revision did not.
