CFRP replaces UHMWPE in knee implants


Hinges in a newly developed knee replacement technology are made from carbon-fiber reinforced (CFR) polyetheretherketone (PEEK).

Aesculap, a division of healthcare supplier B. Braun Melsungen, is using PEEK-OPTIMA CFR in its FDA 510k-cleared and CE-Marked EnduRo knee revision system.

Design engineers hope the use of carbon fiber, the same reinforcement that's used in the fuselage of the Boeing 787 Dreamliner, will overcome the major failure points in knee replacements: dislocation, wear and malpositioning associated with metal components.
