Functional outcomes of direct anterior approach hip arthroplasty: Oblique ‘bikini’ versus longitudinal skin incision

Abstract

Introduction: The direct anterior approach (DAA) for hip arthroplasty has gained popularity in recent years with numerous articles suggesting that short-term outcomes are advantageous over alternative approaches. The ‘bikini’ inguinal crease line incision is a novel variant of the DAA, which reduces the scar. Methods: We conducted a retrospective cohort study to assess functional and general health outcomes and complications of the two different surgical incisions used in DAA total hip arthroplasty (i.e. ‘bikini’ and longitudinal incisions). Results: We found no statistical difference between the novel bikini incision and the traditional DAA hip arthroplasty. Conclusion: This approach offers a cosmetically improved scar with no compromise in outcomes.
