  • 1

    Total hip arthroplasty (THA) is effective for hip disorders, yet 7–15% of patients report dissatisfaction post-surgery.

  • 2

    Structural leg length discrepancy (sLLD) greater than 10 mm correlates with patient dissatisfaction after THA.

  • 3

    Perceived leg length discrepancy (pLLD) can occur even with minimized sLLD, affecting gait mechanics and daily activities.

  • 4

    This study investigates the link between global spinopelvic coronal flexibility and pLLD following THA.

  • 5

    Reduced preoperative spinopelvic lateral flexion may increase the risk of pLLD after total hip arthroplasty.
