The varus ankle and cavus foot pose challenges in surgical correction with regard to total ankle replacement surgery. Etiology of cavus foot type and varus ankle must be evaluated and confirmed. Pes cavus is increased height of the arch with metatarsus adductus and increased calcaneal inclination angle. There often is intrinsic musculature irregularity leading to imbalance of the foot. Although not all cavus foot types and varus ankle deformities are sequelae of neuromuscular disorder, neurologic etiology must be considered. Attaining neutral alignment of ankle joint articular surface is paramount to longevity and functionality of ankle joint replacement implant.
