The US Food and Drug Administration (FDA) has approved a new prosthetic total ankle replacement device as an alternative to fusion surgery for those with arthritic or deformed ankles.
The Scandinavian Total Ankle Replacement System (STAR) made by Small Bone Innovations in Morrisville, Pennsylvania, is the first of its kind in the United States.
The STAR device offers patients more mobility to move the foot up and down than fusion surgery and other FDA-approved fixed-ankle replacement systems. It operates using a mobile-bearing system that moves across a flexible polyethylene surface that does not restrict the ankle joint from rotating.
