“…The position of the calcaneus during walking in healthy participants is different from that in patients with foot problems. The lateral shift of the calcaneus during walking in children with flatfoot results in a low first peak KAM because of the point of GRF application due to the calcaneal position [ 33 ]. In fact, shoe modifications produce a lateral shift in the point of GRF and reduce the first peak KAM in healthy adults [ 34 ].…”

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

Background Accumulating evidence indicates that abnormal foot posture and function are risk factors for knee osteoarthritis (OA). However, the relationship between foot posture and function and tibiofemoral contact force (CF) during habitual weight-bearing activities remains unclear. This study aimed to determine the association between CF and foot posture and function while walking. Methods In total, 18 patients with knee OA and 18 healthy individuals participated in this cross-sectional study. Foot parameters were evaluated by foot Posture Index (FPI), Staheli Arch Index (SAI), hallux valgus angle, calcaneus inverted angle relative to the floor as a static rearfoot posture, navicular height, and toe grip strength. In addition, all participants underwent kinetic and kinematic measurements during a self-selected speed gait. The measurement device used was the three-dimensional motion analysis system with a sampling rate of 120 Hz. The musculoskeletal model, which has 92 Hill-type muscle-tendon units with 23 degrees of freedom, was used to calculate CF. Pearson's correlation coefficient was used to investigate the association between foot parameters and total, medial, and lateral CF of the first and second peaks. Results A significant negative correlation was observed between Walking SAI and first medial CF in control participants (r = -0.515, p = 0.029). SAI was also significantly positively correlated with first medial CF in patients with knee OA (r = 0.488, p = 0.040). Conclusions Our findings reveal a correlation between the medial first peak CF and the SAI. This study indicates that people with knee OA and flatfoot have excessive first medial CF during walking.

“…Moreover, late stance hip extension and knee varus and rotation moments were diminished [26], while mean ankle moment and power during push-off attenuated [30]. In the frontal plane, the knee abduction moment (KAM) was smaller in FFF [37].…”

“…A notable inconsistency arises regarding knee valgus in the frontal plane, as evidenced by findings in [18,26,33], in contrast to the absence of such observations in [31,37]. This discrepancy could be attributed to methodological disparities, including variations in exclusion criteria for knee valgus deformities [37] or demographic factors such as overweight status. Overweight children often exhibit a higher prevalence of knee valgus in conjunction with FFF [50].…”

“…Lower body kinematics in the sagittal plane exhibited a reduced range of plantarflexion during push-off [30,39] and increased knee flexion [30,33]. Notably, frontal plane dynamics indicated heightened knee valgus [26,33], although the presence of knee valgus has been contested [31,37]. Furthermore, in the transverse plane, increased knee rotation ranges and increased peak internal rotation were observed [19].…”

Background: Flatfeet in children are common, causing concern for parents due to potential symptoms. Technological advances, like 3D foot kinematic analysis, have revolutionized assessment. This review examined 3D assessments in paediatric idiopathic flexible flat feet (FFF). Methods: Searches focused on paediatric idiopathic FFF in PubMed, Web of Science, and SCOPUS. Inclusion criteria required 3D kinematic and/or kinetic analysis during posture or locomotion, excluding non-idiopathic cases, adult feet, and studies solely on pedobarography or radiographs. Results: Twenty-four studies met the criteria. Kinematic and kinetic differences between FFF and typical feet during gait were outlined, with frontal plane deviations like hindfoot eversion and forefoot supination, alongside decreased second peak vertical GRF. Dynamic foot classification surpassed static assessments, revealing varied movement patterns within FFF. Associations between gait characteristics and clinical measures like pain symptoms and quality of life were explored. Interventions varied, with orthoses reducing ankle eversion and knee and hip abductor moments during gait, while arthroereisis normalized calcaneal alignment and hindfoot eversion. Conclusions: This review synthesises research on 3D kinematics and kinetics in paediatric idiopathic FFF, offering insights for intervention strategies and further research.
