“…Flatfoot patients are more vulnerable to develop patellofemoral pain syndromes, which are believed to be associated with the coupling of abnormal foot alignment and kinematics resulting in additional stress to the knee [8]. Individuals with pronated foot have a larger peak patellofemoral contact force [11]. The foot orthosis reduced the patellofemoral joint force, which could potentially inhibit flatfoot-induced knee joint problems.…”

Flatfoot is linked to secondary lower limb joint problems, such as patellofemoral pain. This study aimed to investigate the influence of medial posting insoles on the joint mechanics of the lower extremity in adults with flatfoot. Gait analysis was performed on fifteen young adults with flatfoot under two conditions: walking with shoes and foot orthoses (WSFO), and walking with shoes (WS) in random order. The data collected by a vicon system were used to drive the musculoskeletal model to estimate the hip, patellofemoral, ankle, medial and lateral tibiofemoral joint contact forces. The joint contact forces in WSFO and WS conditions were compared. Compared to the WS group, the second peak patellofemoral contact force (p < 0.05) and the peak ankle contact force (p < 0.05) were significantly lower in the WSFO group by 10.2% and 6.8%, respectively. The foot orthosis significantly reduced the peak ankle eversion angle (p < 0.05) and ankle eversion moment (p < 0.05); however, the peak knee adduction moment increased (p < 0.05). The reduction in the patellofemoral joint force and ankle contact force could potentially inhibit flatfoot-induced lower limb joint problems, despite a greater knee adduction moment.

“…Flatfoot would induce other proximal joint problems, such as patellofemoral pain, owing to the coupled excessive foot pronation [8,10]. Razeghi et al [11] reported that excessive pronation in the subtalar joint produces a large patellofemoral force. In addition, excessive eversion of the hindfoot excessively rotates the tibia.…”

“…Introduction: Foot hyper pronation may cause malalignment of the lower extremity, frequently leading to structural and functional deficits both in standing and walking [1]. Based on coupling between rear foot frontal plane motion and rotation of tibia, it is speculated that excessive pronation results in abnormal tibial rotation which increases stress on the joints of the lower extremity during weight bearing [2]. It has been postulated that abnormal subtalar joint motion is linked to knee joint problems like patellofemoral pain syndrome as it may affect knee mechanics.…”

“…Barefoot, level walking data were collected at selfselected speed using 12 Vicon MX cameras. Multi-segment foot motion was obtained using the Oxford Foot Model (OFM) [2]. Discrete, kinematic variables were extracted from the data, including average data during stance and swing, as well as range of motion across the whole gait cycle, for the hindfoot, forefoot and hallux.…”
