Pes planus (flatfoot) is a deformity characterized by loss or reduction of the medial longitudinal arch of the foot, resulting in hindfoot valgus, forefoot abduction, and altered biomechanics. It may be flexible or rigid, congenital or acquired, and can occur in both children and adults. Most pediatric flexible flatfeet are physiological and asymptomatic, whereas adult-acquired flatfoot is commonly associated with posterior tibial tendon dysfunction (PTTD). Diagnosis is based on clinical examination, weight-bearing radiographs, and assessment of flexibility and associated deformities. Treatment ranges from reassurance and orthoses to tendon reconstruction, osteotomies, arthrodesis, or corrective surgery depending on severity and etiology.
