The best approach to use when performing THA is controversial. We did a prospective, nonrandomized multicenter study of 1089
THAs to evaluate patient-centered hip scores and dislocation and revision rates when comparing anterolateral and posterior
hip approaches at 5 years’ followup. Patients were divided into two groups depending on which surgical approach was used:
anterolateral or posterior. The primary outcome measure was change in Oxford hip score. At 5 years, there were no differences
in change in Oxford hip score and in dislocation or revision rates between the groups.
