Pes Planus eMedicine Orthopedics

Description: Progressive pes planus, or flatfoot, deformity in adults is a common entity that is encountered by orthopedic surgeons. Despite the significant incidence of this condition, the pathophysiology is still debated. The failure of one anatomic entity alone is unlikely to explain the clinical presentation of adult-acquired flatfoot deformity (AAFD). Instead, a mismatch between active and passive arch stabilizers is a more likely scenario
