Comparison of direct anterior approach and posterior approach total hip arthroplasty: More than 5-year follow-up

In this study we compare the surgical outcome of DAA and PA more than 5-year follow-up evaluation. This is a retrospective cohort single-surgeon study of consecutive primary THAs using the DAA or PA. There was no significant difference in HHS and JHEQ score. Posterior dislocation occurred in 4 cases in PA group (9.5%, p = 0.038) while there was no dislocation in DAA group. Both DAA and PA yield good results at the final follow-up in terms of function, quality of life, and survivorship. However dislocation was significantly higher in PA group.
