The Scandinavian Total Ankle Replacement (STAR) System

The Scandinavian total ankle replacement (STAR) system is a mobile-bearing design that has been used both in the United States and Europe to treat advanced arthrosis of the tibiotalar joint. The purpose of this study was to review the history of the implant, describe its design, highlight important aspects of its surgical technique, and assess the available results after STAR implantation in the literature. In the STAR, surgeons resect only minimal bone and permit motion in multiple planes without causing undue stress at the bone-implant interface. Although the results to date are promising, longer-term efficacy needs to be assessed in future studies.
