Total ankle replacement in the varus ankle.

Treatment of ankle varus with total ankle replacement (TAR) lacks consensus regarding the limits of deformity that can be managed successfully without recurrence. With newer anatomic prosthetic designs and a comprehensive surgical approach, treatment of frontal plane deformities with implant arthroplasty has gained acceptance. The purpose of this retrospective study was to determine the outcome and compare correction of large frontal plane varus deformities with TAR using 2 different replacement systems.
