Knee osteoarthritis (OA) is a progressive degenerative joint disorder characterized by cartilage degradation, pain, and impaired mobility. This observational study explores gender-specific differences in weight-bearing patterns among individuals with grade 2 and grade 3 knee OA, utilizing sensor plate technology for objective assessment. Participants included males and females aged 55-70, with data indicating increased asymmetry and midline shift in weight distribution among those with grade 3 OA. These biomechanical deviations were more pronounced in females, correlating with higher symptom severity as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores.
Sensor plate analysis revealed compensatory gait adaptations and load imbalances, particularly in female participants, who often demonstrated altered plantar pressure and greater lateral deviation. These findings suggest that anatomical and biomechanical differences such as wider pelvis and higher Q-angle in females may contribute to increased OA severity and altered loading patterns. The results underscore the need for sex-specific evaluation in OA management.
Tailored rehabilitation strategies, including custom orthotics and gait retraining based on sensor data, may help correct biomechanical inefficiencies, reduce joint stress, and slow disease progression. Incorporating sensor plate analysis into routine assessment can enhance diagnosis, guide personalized interventions, and improve functional outcomes in individuals with knee OA.
