Coronal plane deformity can pose difficulties with balancing in Total Ankle Replacement (TAR). Current reports outline improved outcomes in the presence of varus deformity. Soft tissue balancing techniques are well described, but are limited by no link to eitiology and pathoanatomy of the deformity. A prospective review of all the TAR by the senior author was performed to identify cases of pre-operative varus greater than 10°. A chart review was performed to identify aetiology, intraoperative findings, and operative techniques to achieve a balanced TAR. X-rays were examined to measure deformity and amount of correction. Volumetric rendering and segmentalisation was performed on pre- and post-CTs to identify anatomical defects, osteophyte formation, rotational and translational changes of the hindfoot joints.Introduction
