Total ankle arthroplasty in end-stage ankle arthritis

Abstract

Recent advancements in ankle prosthesis design, combined with improved surgical techniques for correction of coronal plane deformity and ligamentous balancing, have led to a resurgence of interest in total ankle arthroplasty for the treatment of end-stage ankle arthritis. Although ankle arthrodesis has long been considered the gold standard treatment for ankle arthritis, recent studies have shown that patients who undergo total ankle replacement have equivalent pain relief and improved function, when compared with patients with an ankle fusion. The purpose of this review is to summarize the indications, advantages, disadvantages, and clinical outcomes of some of the more commonly used modern prostheses for total ankle arthroplasty.
