摘　　要：Flatfoot is defined as the flattening of the medial arch of the foot,and it is classified into flexible flatfoot and rigid flatfoot based on whether the flattening of the medial arch of the foot can be reset when standing on toes.The insole is the most basic and common treatment,which is relatively cheaper and easier to adopt.Three-dimensional(3D)printing,an emerging technology characterized by high machining accuracy and use of various materials,can be utilised in personalised insoles,which have good application prospects.Further research on the clinical effects of 3D-printed insoles is still needed.In this study,64 cases of 3D-printed insoles were clinically observed.The results showed that 3D-printed insoles had statistically positive effects in treating flatfoot(P=0.00017),and with adjustment and adaptation,their comfort and clinical effect can be improved.This study provides an empirical reference for further large-scale clinical control research.
