Based on proprietary CT reconstruction studies, the tibia and talar components were designed to mimic patients’ natural anatomy. Specifically, the curved talus component aligns with the talus’ trabecular bone structure for inherent stability while the flat cut talus provides initial fixation through its press-fit bone cage and plasma pegs.2 Meanwhile the tibia is designed to provide anatomic cortical coverage and account for fibular articulation.1,2

Vantage® Total Ankle System
The Vantage Total Ankle Systems achieve a new vantage point by combining engineering and surgeon expertise to address clinical challenges and patient outcomes. Our proprietary CT reconstruction studies evaluated both healthy and diseased ankles to shape our curved and flat cut taluses and tibia components.1
Features of the Vantage Total Ankle System
Watch design team surgeon Mark Easley, MD, explain why he uses the Vantage Total Ankle System and the benefits of the curved talus design.
Anatomic Redefined
Fixation
The tibia’s press-fit bone cage and plasma pegs create initial fixation while the talar component’s curve-on-curve shape is designed to provide stability in the A/P direction. The talar components’ pegs also provide stability in the medial/lateral, and cement should be used on both the talar and tibia for fixation.
Bone Removal
The curved talar design addresses the disease process by reducing the amount of talar preparation required. The radius of the curvature on the underside of the talar component is based on studies that analyze the effect of an arthritic talus.2
Reliability
The innovative tibial design and surgical technique are intended to preserve the integrity of the tibia anterior cortex while the anterior talar shield is designed to provide increased surface area that addresses subsidence.
