    Legg–Calvé–Perthes disease (LCPD) can lead to permanent hip deformities, increasing pain and the risk of osteoarthritis in adulthood.

  • 2

    Surgical intervention for severe LCPD aims to reduce pain and improve function, with a notable surgical failure rate of 16%.

  • 3

    A dynamic biomechanical digital twin model can predict chondrolabral stress and inform treatment decisions for LCPD.

  • 4

    The study developed a digital twin model to evaluate sensitivity to variations in material properties and joint angle measurement errors.

  • 5

    MRI data was utilized to create patient-specific input parameters for the digital twin model, enhancing its accuracy in simulating hip mechanics.
