  • Three-dimensional (3D) motion analysis of knee joint biomechanics.

Related Experiment Videos

  • Correlation analysis between risk factors and biomechanical parameters.

    • Main Results:

    • Specific risk factors were quantitatively linked to altered knee joint kinematics and kinetics.
    • 3D motion analysis demonstrated how biomechanical changes mediate the effect of risk factors on OA pathogenesis.
    • Significant associations were found between factors like obesity and joint loading patterns.

    Conclusions:

    • The pathogenesis of knee OA involves complex interactions between epidemiological risk factors and biomechanical alterations.
    • 3D motion analysis provides a valuable tool for understanding the mechanistic pathways of knee OA.
    • These findings can inform targeted interventions for knee OA prevention and management.
