Official title: A Clinical Comparison in Wound Healing of Bikini Versus Longitudinal Incision in Direct Anterior Approach Total Hip Arthroplasty in the Obese Patient Population: A Randomized Control Trial
Run by University of Miami · NCT06831045 · Data updated 2026-11-12
This study is testing whether a bikini-style incision or a longer incision during hip replacement surgery helps people heal better and feel more satisfied with their results.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients with a body mass index of 30 or greater who are scheduled for primary unilateral total hip arthroplasty.
✕Probably not a fit
Patients with a body mass index less than 30 or those with prior hip surgeries will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to evaluate the differences in wound healing and participant satisfaction between two types of incisions—bikini and longitudinal—used during total hip arthroplasty performed via the direct anterior approach. Patients with a body mass index of 30 or greater who are undergoing primary unilateral hip replacement will be included. The study will assess outcomes related to recovery and satisfaction to determine if one incision type offers advantages over the other.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical techniques that enhance recovery and satisfaction for patients undergoing hip replacement.
How similar studies have gone: While there may be studies comparing incision types in other surgical contexts, this specific comparison in the direct anterior approach for total hip arthroplasty is relatively novel.
