About this study
Official title: The Role of Iliotibial Band Stiffness Assessed by Shear-Wave Elastography in Objective and Perceived Leg Length Discrepancy After Total Hip Arthroplasty
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.
Read the detailed description
This study will include adult patients aged 18-90 years who underwent unilateral primary total hip arthroplasty at least 12 months prior to enrollment.
Patients will undergo clinical evaluation, functional scoring, radiographic assessment, and bilateral ITB stiffness measurement using shear-wave elastography.
Radiographic leg length discrepancy will be assessed using previously obtained pelvis AP and full-leg length radiographs without additional imaging exposure.
Perceived leg length discrepancy will be evaluated using a block test during standing examination.
ITB stiffness will be measured bilaterally at standardized anatomical landmarks using SWE by two experienced radiologists.
The primary aim is to assess correlations between ITB stiffness and radiographic LLD, as well as perceived LLD. Secondary analyses will evaluate whether ITB stiffness predicts PLLD independently of radiographic LLD.

Shear-Wave Elastography (Ultrasound)Diagnostic test
Non-interventional ultrasound performed during routine follow-up.
| Study group | Role | What they receive |
|---|---|---|
