Flexible Flatfoot (Pes Planus)

What is a Flexible Flatfoot?

Understanding the condition

Flexible flatfoot, also called pes planus, is a common condition in children where the arches of the feet appear flattened, especially when standing. In most cases, the arch reappears when the child is sitting or standing on tiptoes. Flexible flatfoot is usually painless and considered a normal part of development, but in some children, it can cause fatigue, discomfort, or difficulty with physical activity.

Signs & Symptoms

How We Diagnose Flexible Flatfoot

Diagnosis includes a physical examination to check arch appearance in standing and tiptoe positions, gait and alignment, and Achilles tendon tightness. Imaging is usually not needed; X-rays are considered only if pain, stiffness, or another condition is suspected.

How We Heal a Flexible Flatfoot

How is surgery performed?

Surgery is rarely needed. For persistent, symptomatic cases that don’t improve with conservative care, procedures may include soft-tissue lengthening (e.g., Achilles), bone realignment procedures (such as calcaneal osteotomy), or arthroereisis (a small implant to support the arch). Dr. Malek Abu-Al-Nadi recommends surgery only when clearly necessary, with a priority on conservative care first.e
