BACKGROUND AND OBJECTIVE

Current diagnostic testing lacks effectiveness in early-stage knee osteoarthritis (KOA). Specific treatment addressing pathomechanics is missing which can potentially slow down or halt disease progression. 3D analyses of joint kinematics and kinetics are rare, but can identify subtle gait alterations in early stages, and compare biomechanical differences across varying KOA severities which could improve tailored needs at any disease stage.

By analyzing lower limb biomechanical changes at different stages of injury, this study aimed to uncover early pathological biomechanical features of KOA and target rehabilitation recommendations, to enhance treatment efficiency and delay disease progression.

Gait retraining programs should optimize step width and swing time to reduce abnormal frontal-plane loads and improve swing propulsion.

METHODS

  • 45 subjects were recruited from the Sports Rehabilitation Center of Guangzhou Sport University.
