Use of the Maxwell-Brancheau arthroereisis implant for the correction of posterior tibial tendon dysfunction.

Successful management of the flexible flatfoot deformity relies not only on correcting causal factors, but also on addressing the adaptive changes that have occurred and any coexisting deformities present. The three primary goals of any therapy--relief of pain, biomechanical control of excessive pronation, and prevention of the progression of the deformity--should be considered. With thorough assessment of causal factors and planal dominance of the deforming and compensative forces, one can expect to increase the predictability and success of the surgical management of PTTD in the flexible adult flatfoot deformity.
