Age, gender, obesity, and depression are associated with patient-related pain and function outcome after revision total hip arthroplasty.
To examine whether patient characteristics predict patient-reported pain and function 2- or 5-years after revision total hip arthroplasty (THA). In a prospective cohort of revision THA patients, we examined whether gender, age, body mass index (BMI), comorbidity (Deyo-Charlson index) and depression predicted moderate-severe hip pain, moderate-severe activity limitation (> or = 3 activities), dependence on walking aids and use of pain medications, using multivariable regression analysis. Significant predictors of moderate-severe pain at 2- and 5-years were [odds ratio (95% confidence interval)]: female gender, 1.3 (1.0, 1.6) and 1.5 (1.1, 1.9) and age 61-70, 0.7 (0.5, 1.0) and 0.7 (0.5, 1.0; reference (ref), < or = 60 years). ⋯ Similarly, female gender, older age (>70) and BMI of 30 or higher were each significantly associated with higher odds of moderate-severe activity limitation at both, 2- and 5-years. Depression was associated with higher risk at 2 years, 1.7 (1.1, 2.6) and higher Deyo-Charlson score with a higher risk of moderate-severe activity limitation at 5 years, 1.7 (1.1, 2.7). Obesity and depression, considered modifiable clinical factors, were important independent predictors of pain, functional limitation and use of pain medications, following revision THA.
