STAR Ankle
STAR® Ankle
Simplified & Flexible Mobile
Bearing Total Ankle
Now simplified, the Scandinavian Total Ankle Replacement (STAR® Ankle) serves as a non-cemented implant to alleviate pain in arthritic ankle joints caused by osteoarthritis, post-traumatic arthritis, or rheumatoid arthritis.
Before STAR® Ankle, surgeons faced limited choices for total ankle arthroplasty. With STAR® Ankle, surgeons now have access to the first three-piece mobile bearing ankle implant approved for uncemented use in the United States.
STAR® PSI is only available for sale in the U.S.

Proven
With its 37-year history, the STAR® has been implanted globally over 40,000 times. Demonstrating its efficacy through prospective outcome studies, the STAR® boasts the highest published long-term metal component survival rates in the U.S. and Canada.1,2,4,5,6
Flexible
The STAR’s® modular components and positional forgiveness allow for 225 patient matched configurations with just one surgical technique. While rotating across the axial plane, mobile bearing allows for reduced point contact stress comparative to fixed bearing.3,7

Resilient
e+™ Polyethylene is enhanced with the free radical-neutralizing antioxidant vitamin E, which provides superior resistance to oxidation, ensuring consistent wear rates and maintaining its resilience over time.
Dependable
The mechanical properties of e+™ Polyethylene remain dependable and stable, even under conditions of accelerated aging. This stability is crucial for ensuring long-term performance and patient satisfaction.
Lasting
e+™ Polyethylene is formulated to deliver exceptional wear performance over extended periods. By incorporating vitamin E, the material avoids the need for re-melting resulting in enhanced strength and lasting resistance to wear.
