Since the introduction of the newer generation of total ankle prostheses for the treatment of ankle arthritis, surgeons have been evaluating their intermediate-term results and refining their technique. With the substantial learning curve, experienced surgeons are better able to define clinical pearls and pitfalls.Conti presented the intermediate-term results of 120 total ankle arthroplasties that had been performed with use of the Agility prosthesis (DePuy, Warsaw, Indiana)1. Although patients reported a high degree of satisfaction after an average duration of follow-up of four years, complications were well defined during this period. These complications included eight medial malleolar fractures and one lateral malleolar fracture. The prevalence of component malpositioning was 10%, the prevalence of postoperative varus positioning of the talar component was 7%, and the prevalence of syndesmotic nonunion was 3%. Another series demonstrated a substantial learning curve with a decreasing prevalence of well-defined complications after total ankle arthroplasty2. The senior author reported more complications in his first group of twenty-five patients (six minor wound complications, four nerve or tendon lacerations, and five intraoperative fractures) than in his second group of twenty-five patients (two minor wound complications and two fractures).
