Abstract Background Accumulating evidence indicates that abnormal foot posture are risk factors for knee osteoarthritis (OA). However, the relationship between and tibiofemoral contact force (CF) during habitual weight-bearing activities remains unclear. This study aimed to determine association CF while walking. Methods In total, 18 patients with OA healthy individuals participated in this cross-sectional study. Foot parameters were evaluated by Posture Index (FPI), Staheli Arch (SAI), hallux valgus angle, calcaneus inverted angle relative floor as a static rearfoot posture, navicular height, toe grip strength. addition, all participants underwent kinetic kinematic measurements self-selected speed gait. The measurement device used was three-dimensional motion analysis system sampling rate of 120 Hz. musculoskeletal model, which has 92 Hill-type muscle–tendon units 23 degrees freedom, calculate CF. Partial correlations investigate medial, lateral first second peaks controlling gait speed. Results A significant negative correlation observed Walking SAI peak medial control ( r = -0.505, p 0.039). also significantly positively correlated 0.482, 0.042). Conclusions Our findings revealed SAI. people flatfoot have excessive
