Stryker Launches Citrefix Suture Anchor System, Featuring Award-winning Citregen Biomaterial

Stryker recently announced the launch of Citrefix a suture anchor system for foot and ankle surgical procedures. The new system uses a citrate-based biomaterial referred to as Citregen, a bioresorbable material designed to mimic the chemistry and structure of native bone. Citrate-based biomaterials were originally developed by Guillermo Ameer’s team at Northwestern University for tissue engineering and regenerative medicine applications. Ameer was awarded the Society for Biomaterials Technology Innovation and Development Award in 2022 for his work on these materials. Polydiolcitrates are the first biodegradable thermoset polymers used for implantable medical devices cleared by the U.S.A. Food and Drug Administration for use in surgeries.  

Citrefix is a disposable suture anchor system that features a resorbable biomimetic anchor body. Citregen enables controlled resorption without chronic inflammation. Citregen's unique chemical and mechanical properties are designed to help grafted tissue heal and healthy bone grow when used in orthopaedic surgical applications. After the launch of Citrelock in 2021, Citrefix is the second product in Stryker’s portfolio using the material, with additional products expected in 2023.
