Surgical Considerations for Revision Flatfoot Reconstruction: Overcorrection/Undercorrection

Reconstructive surgery of the symptomatic pes planus deformity is a very common procedure with relatively good outcomes. Many factors such as patient selection, patient expectations, and surgical execution can influence the results. In addition to achieving osseous union, the overall postoperative alignment is critical in determining functional outcome. Specifically, under- and over-correction respectively present their own unique problems and symptomatology. The purpose of this review is to discuss the adverse outcomes after mal-reduction of flatfoot reconstruction and emphasize the strategies to correct the subsequent deformity.
