| 概要 | OBJECTIVE:To investigate plantar pressure (PP) distributions in patients with knee osteoarthritis (OA) and their correlations with foot morphology.DESIGN:This was a cross-sectional study.SETTING:Participants were recruited from two local orthopedic clinics.PARTICIPANTS:Fifty-two female patients with symptomatic medial knee OA (Kellgren-Lawrence grade ≥2) and 38 healthy older controls aged 60 years or older.INTERVENTIONS:Not applicable.MAIN OUTCOME MEASURES:Hallux valgus angle, navicular/foot ratio, and calcaneus eversion angle were measured as foot morphology indices. PP distribution was recorded during comfortable walking using a PP distribution platform. Statistical parametric mapping (SPM) analysis of variance was conducted to compare PP between knee OA patients and healthy controls. SPM correlation analyses were performed to confirm the correlation between PP and foot morphology variables in knee OA group.RESULTS:Compared with the control group, peak PP values under the first metatarsophalangeal joint (1st MPJ), lateral midfoot, and heel region were larger (all p<0.01) in knee OA patients. Whereas under the toe and medial midfoot region, peak PP was not significantly different. Positive correlations were found between 1st MPJ PP and the hallux valgus angle (p<0.01), as well as between heel PP and both the navicular/foot ratio and calcaneus eversion angle (p<0.01). While under the midfoot region, no significant correlation was observed.CONCLUSION:Knee OA patients showed increased localized plantar pressure during walking, as well as a potential association between the PP and foot morphology. These findings could contribute to the development of future treatment interventions for knee OA, including insoles or shoes modifying foot deformity and PP distribution. |
