When the patient suffers from arched foot, in appearance, the patient can see that the foot is curved anteriorly and posteriorly, the arch of the foot is relatively high, and the toes in the metatarsophalangeal joints flex to the dorsal side in the shape of a claw, so that the middle part of the sole of the foot can not be able to touch the ground when standing up. The majority of cases of this condition are treated surgically. Soft tissue release and bony surgery can be performed. Depending on the age of the patient and the degree of the condition, different treatments are used. In principle, soft tissue surgery can be done first, which can include soft tissue release on the plantar side of the foot, tibialis anterior and tibialis posterior tendon displacement and toe extensor posterior displacement.
