Trial Summary

What is the purpose of this trial?

The study team is conducting this study to see if there is a difference between the wound healing and participant satisfaction rates between two incision types used during a THA done via the DAA technique.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Bikini Incision and Longitudinal Incision for Total Hip Arthroplasty?

Research suggests that the bikini incision may lead to better-looking scars and higher patient satisfaction compared to the traditional longitudinal incision, while also potentially reducing wound complications. ^{1 2 3 4 5}

Is the bikini incision safe for total hip arthroplasty?

Research shows that both bikini and traditional longitudinal incisions for hip replacement are generally safe, with the bikini incision potentially reducing wound complications and improving scar appearance. ^{1 2 3 4 5}

How does the bikini incision treatment differ from the longitudinal incision in hip replacement surgery?

The bikini incision for hip replacement surgery is unique because it follows the natural skin crease, potentially leading to a more aesthetically pleasing scar and improved patient satisfaction compared to the traditional longitudinal incision. It may also reduce wound complications, although there is a concern about increased muscle damage. ^{1 2 4 5 6}

Eligibility Criteria

This trial is for individuals undergoing Total Hip Arthroplasty (THA) using the Direct Anterior Approach (DAA). Specific eligibility criteria are not provided, but typically participants would be adults in need of hip replacement who meet surgical requirements.

Inclusion Criteria

I am scheduled for a first-time hip replacement surgery.

I am having a hip replacement on one side.

My BMI is 30 or higher.

Exclusion Criteria

Patients with body mass index less than 30

I cannot or do not want to have spinal anesthesia.

I am allergic or cannot take certain drugs used in the University of Miami's hip replacement protocol.

Treatment Details

Interventions

• Bikini Incision
• Longitudinal Incision

Trial Overview The study compares wound healing and patient satisfaction between two types of incisions: a bikini incision and a longitudinal incision, both performed during THA via DAA. The goal is to determine if one results in better outcomes.

Participant Groups

Group I: Longitudinal Incision Group Experimental Treatment 1 Intervention

Participants in this group will receive the longitudinal incision during THA. Total participation is up to 90 days.

Group II: Bikini Incision Group Experimental Treatment 1 Intervention

Participants in this group will receive the bikini incision during THA. Total participation is up to 90 days.
