Outcome Measures
Primary Outcomes (3)
Wound Healing measured in number of days
Will be measured in number of days the incision will take to heal.
Up to 14 days
Patient satisfaction with scaring as measured by Patient Scar Assessment Scale
Score ranges from 0 to 10. Higher scores indicate less satisfaction
Up to to 6 months
Scar cosmesis as measured by Observer Scar Assessment Scale
Score ranges from 0 to 10. Higher scores indicate worse scar cosmesis
Up to 6 months
Secondary Outcomes (5)
Number of participants who report lateral femoral cutaneous nerve-related symptoms
Up to 6 months
Patient reported outcomes as measured by Hip Disability and Osteoarthritis Outcomes
Up to 6 months
Number of intraoperative fractures
Up to 3 hours
Length of surgery measured in minutes
Up to 3 hours
Number of postoperative complications
Up to 90 days
Study Arms (2)
Bikini Incision Group
EXPERIMENTALParticipants in this group will receive the bikini incision during THA. Total participation is up to 90 days.
Longitudinal Incision Group
EXPERIMENTALParticipants in this group will receive the longitudinal incision during THA. Total participation is up to 90 days.
Interventions
Participants will receive the bikini incision in person during THA. A one-time incision will be made along the groin line before standard of care THA surgery. The surgery takes approximately two hours.
Participants will receive the longitudinal incision in person during THA. A one-time linear incision will be made along the thigh before standard-of-care THA surgery. The surgery takes approximately two hours.
