S.T.A.R. Total Ankle
S.T.A.R.™Total Ankle (Stryker, Inc)
The Scandinavian Total Ankle Replacement (S.T.A.R.™), has been available in Europe for approximately 37 years; it is the only 3-part (mobile bearing) device currently available in the United States. More than any other device in the U.S. market, the S.T.A.R.™, has undergone more extensive FDA testing including a direct comparison to ankle fusion, yielding superior results. The prosthesis was purchased by Small Bone Innovations in 2008 and became fully available for use in the United States in 2009. The first placement was in Seattle in 2010 at Swedish Medical Center.
With over 30,000 placements worldwide, it has been the most researched of ankle implants in the world. Its design allows for the middle component made of medical grade plastic to pivot between the other metal surfaces (referred to as a mobile bearing) and has variable thickness options, allowing the surgeon to fine tune ligament tension to optimize function. The S.T.A.R.™ is a proven design with newly redesigned instruments for accurate placement.
This lower profile device is generally considered an optimal primary implant since it removes less bone, does not require fusion of the leg bones, can be placed with less operating time, and offers a quicker return to activity, often with partial weightbearing at 4 weeks. Most insurance plans in Washington State as well as the Northwest cover ankle joint replacement (arthroplasty) including the S.T.A.R. device.
