Role of Iliotibial Band Stiffness in Perceived Leg Length Discrepancy After Total Hip Arthroplasty
Turkey (Türkiye)68 participantsStarted 2026-01-14
Plain-language summary
Patients undergoing total hip arthroplasty (THA) may experience objective or perceived leg length discrepancy (LLD/PLLD), which can negatively affect gait, pelvic balance, and patient satisfaction.
The iliotibial band (ITB) plays a critical role in lateral thigh tension transmission, and alterations in its stiffness may influence the perception of limb length discrepancy.
Shear-wave elastography (SWE) is a noninvasive ultrasound-based technique that enables quantitative assessment of soft tissue stiffness.
This cross-sectional observational study aims to investigate the relationship between ITB stiffness measured by SWE and both radiographic and perceived leg length discrepancy in adult patients who underwent unilateral primary THA at least 12 months previously.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Age between 18 and 90 years History of unilateral primary TKA, with no prior revision surgery At least 12 months after surgery and returned to functional weight-bearing No use of walking aids, or use of a cane only for outdoor ambulation
Exclusion Criteria:
Bilateral TKA or severe osteoarthritis in the contralateral hip History of femoral, tibial, or hip surgery resulting in limb length-altering deformity Significant scoliosis (\>20° Cobb angle) or pelvic obliquity \>5° Neurological disorders (e.g., severe polyneuropathy, hemiparesis) History of lateral thigh surgery (e.g., IT band release, TFL surgery) Body mass index (BMI) \>40 (may reduce the reliability of SWE measurements) Suspected prosthetic joint infection or implant instability
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
