Total Ankle Replacement in the Presence of Talar Varus or Valgus Deformities.

Patients presenting with end-stage ankle arthritis with coronal plane talar deformities have a variety of complex multidirectional deformities that require careful preoperative assessment and a clear understanding of the pathophysiology. Surgeons managing these patients with total ankle arthroplasty need to be familiar with extra-articular and intra-articular surgical methods to correct pes planus and pes cavus deformities, including bony procedures and soft tissue procedures. Performing these procedures in 1 or 2 stages depends on surgeon preference and the severity of the deformities. This article recommends a two-staged reconstruction for more severely deformed feet.
