Knee osteoarthritis affects females more than males, with distinct gender-based gait biomechanics observed in patients. Osteoarthritic females showed altered knee movement, unlike males, suggesting gender-specific treatment needs.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Gerontology

Background:

  • Knee osteoarthritis (OA) is significantly more prevalent in females (2-3x) than males.
  • Gender predisposition to knee OA may be linked to biomechanical gait differences.
  • Understanding these differences is crucial for targeted interventions.

Purpose of the Study:

  • To investigate gender-based biomechanical differences in gait patterns of individuals with knee OA.
  • To identify specific kinematic and kinetic variations between genders in knee OA patients.
  • To explore the relationship between gender, OA, and gait parameters.

Main Methods:

  • Employed 3D gait analysis on healthy and knee OA cohorts (males and females).
  • Calculated hip, knee, and ankle kinematics and kinetics.

  • Assessed anthropometrics, strength, pain, function, and disease severity.

    • Main Results:

    • Significant gender-disease interaction found in knee flexion angle and moments (sagittal, frontal, transverse planes).
    • Osteoarthritic females exhibited unique knee biomechanics compared to healthy females.
    • Osteoarthritic males maintained similar knee biomechanics to healthy males.
    • No significant differences in anthropometrics, function, or disease severity explained these biomechanical variations.

    Conclusions:

    • Gait patterns in knee OA patients are gender-dependent, differing from healthy individuals.
    • The biomechanics of knee OA progression vary between genders.
    • Gender-specific biomechanical interventions for knee OA should be developed and investigated.
