Background: Foot pain experienced by long-distance runners could be relieved by functional insoles which aim at evenly distributing the plantar pressure.
Research Question: We hypothesised that an individually moulded insole with medial arch support would reduce the impact and loading under the heel and metatarsal regions.
Methods: Twelve male recreational runners ran on a treadmill at 10 km/h for 1 hour with flat insoles and medial arch supported insoles. A pressure insole system (Novel Pedar, Germany) was used to obtain the peak pressure, peak force, time normalised pressure-time integrals, and the percentage of the total force-time integrals under 10 regions.
Results: Medial arch supported insoles reduced the peak force under the heel (medial: -15.3%, p = 0.001; lateral: -19.2%, p = 0.037) during the initial run, and reduced peak pressure under the heel (medial: -13.3%, p = 0.005; lateral: -9.9%, p = 0.006), and peak force under the medial heel (-17.8%, p = 0.006) after the run. The percentage of the total force-time integrals under the heel was reduced (medial: -23.8%, p = 0.004; lateral: -13.6%, p = 0.022) after the run. No significant difference was found under the metatarsal regions. There is shift of load from the metatarsal regions to the medial mid-foot as indicated by the change of the percentage of total force-time integrals.
Significance: Medial arch supported insoles were effective in reducing the impact and loading under the heel region in prolonged running on a treadmill.
Level Of Evidence: Controlled laboratory study, Level V.

Introduction: There is a lack of clinical evidence supporting the decision-making process between high tibial osteotomy (HTO) and unicomparmental knee arthroplasty (UKA) in gray zone indication, such as moderate medial osteoarthritis with moderate varus alignment. This study compared the outcomes between HTO and UKA in such cases and assessed the risk factor for not maintaining clinical improvements.
Materials And Methods: We retrospectively reviewed 65 opening-wedge HTOs and 55 UKAs with moderate medial osteoarthritis (Kellgren-Lawrence grade ≥ 3 and Ahlback grade < 3) and moderate varus alignment (5°< Hip-Knee-Ankle angle < 10°) over 3 years follow-up.

Purpose: To define the anatomical variance between orbital floor and medial orbital wall blowout fractures, and its change with age.
Methods: This was a retrospective, observational study analyzing data from 557 patients with isolated blowout fractures of the orbital floor or medial orbital wall. Axial and quasi-sagittal CT images were analyzed to compare radiologic data on orbital wall morphology between fracture site groups and among age groups.

Autism spectrum disorder (ASD) is a serious neurodevelopmental disorder characterized by impairments in social interaction, language, and communication and induction of stereotypic behavior. In rodents, prenatal administration of valproic acid (often on 12.5 gestational days) is used for the induction of an ASD-like model.

Objective: The purpose of this case study was to report the management of a patient with posterior tibialis tendon injury concurrent with gender-affirming hormone therapy (GAHT).
Clinical Features: A 31-year-old transgender male presented to a chiropractic clinic with spontaneous, right medial foot pain following running that day. Medical history revealed bilateral congenital pes planus and intramuscular administration of testosterone for 8 years.

Background: This study aimed to (1) determine the association between varus knee deformity and ipsilateral foot and ankle morphology, and (2) evaluate the relationship between varus knee deformity and foot and ankle pain in patients with end-stage varus knee osteoarthritis (KOA).
Methods: A total of 213 patients who underwent primary total knee arthroplasty for end-stage varus KOA were enrolled in this study and divided into a 'severe varus group' (n = 119) and a 'mild varus group' (n = 94) based on preoperative knee varus degree. Morphological parameters and pain incidence in the foot and ankle were compared between the two groups.
