Abstract
This study included 143 patients who had revision total hip arthroplasty (THA) and 144 patients who had primary THA. The primary outcome variable in this study was the Western Ontario and McMaster Universities Osteoarthritis Index scores. Univariate and multivariate regression models were used to assess the relationship between surgical procedure and postoperative health related quality of life outcomes. The mean follow-up period was 1.7 years (range, 1-3 years). The mean preoperative function of patients with primary THA was significantly worse than that in the revision group ( δ = −6.2; P = .013). Postoperative functional outcome was significantly better in patients with primary THA ( δ = 6.5, P = .016) than in patients who had revision THA. The magnitude of improvement in quality of life is greater for the patient with primary THA in comparison to the patient with revision THA.
