*Reference category: Loosening/Wear or Osteolysis.
^aMain ADL limitation model was adjusted for 15 covariates/confounders: Age, gender, BMI, ASA class, distance from the medical center, anxiety, depression, Deyo-Charlson index, preoperative limitation in 7 activities.
^bAdjusted for 9 additional covariates/confounders: Age, gender, BMI, Deyo-Charlson comorbidity score, ASA class, distance from the medical center, anxiety, depression and preoperative pain.
