In symptomatic patients, undercorrection of a flatfoot deformity can lead to the need for revision surgery to restore functional mechanics and prevent progression of deformity. The underlying cause of undercorrection is failure to fully recognize or understand the extent of the deformity. This article discusses the typical deformities in adult flatfoot and indications for surgical intervention. Also presented are the surgical procedures for the correction of the typical deformity patterns with available outcome statistics and a stepwise algorithm for patient evaluation to assist in treatment and mitigate the risk of undercorrection of deformity.
