PEEK-Based Polymer is Wear-Resistant

Developed for use in joint arthroplasty, a reinforced PEEK-based polymer exhibits resistance to wear and induces a limited biological response to wear debris. Motis has mechanical properties that qualify it as a potential replacement for metal, ceramic, and polyethylene components. Capable of addressing clinical concerns surrounding metal-on-metal bearing surfaces, the material features a stiffness that provides a better anatomical load distribution than metals, according to its manufacturer. Its strength, creep, and fatigue performance enable its use as a thin cup in a large ceramic head system, enhancing bone conservation. To optimize fixation, the biomaterial can be coated with porous titanium or hydroxyapatite. In addition, it can be injection molded without compromising precision or surface characteristics, and the near-net shapes it can produce help accelerate device development.
