| Abstract Scope |
Orthopedic implants have historically been metal which is far stiffer than bone. The difference in stiffness and other mechanical properties leads to issues such as stress shielding resulting in loss in bone density. To avoid these issues, newer materials with mechanical properties closer to bone have been explored for use as orthopedic implants. One such material is Polyether-ether-ketone (PEEK), though, it has little to no bioactivity on a smooth surface. Therefore, tissue growth does not occur around the implant, and this can lead to loosening. An important in-vitro parameter for determining biocompatibility and osteointegration is surface energy and its relations with hydrophilic behavior. Advancements in additive manufacturing have enabled far more surface micro-nano patterns to be explored. Specifically, this study focuses on surfaces inspired by nature’s super-optimized approach to develop additively manufactured PEEK implants with high osteoconductivity. |
