Surgical Technique of the VANTAGE Total Ankle Arthroplasty

摘要

The VANTAGE total ankle arthroplasty is a novel anatomic mobile or fixed-bearing total ankle arthroplasty with a good and simple instrumentation giving to surgeons a safe implantation ventral approach technique. Our first cases report a successful functional outcome for patients, with or without additional surgeries, and without very early complications. Total ankle arthroplasty (TAA) is an alternative to ankle arthrodesis for treatment of end-stage ankle osteoarthritis (OA) preserving the joint function and reducing the stress in the adjacent joints. TAA began in the 1970s, and the early designs were cemented and highly constrained. The second and third TAA generation were 2-component or 3-component systems with cementless fixation and fixed or mobile polyethylene insert. The fourth and newest TAA generation focuses more on the native anatomy and biomechanics of the ankle and hindfoot.4 The surgeon can choose between mobile and fixed-bearing solutions depending on the ankle and hindfoot pathology. The VANTAGE TAA system represents the fourth and newest TAA generation offering surgeons a 2-component or 3-component system. In this paper, we want to present the features and the surgical implantation technique of the VANTAGE mobile-bearing (ie, 3-component) TAA.
