Abstract:
Polyether ether ketone (PEEK), characterized by a comparable elastic modulus to human bone with high wear resistance, radiolucency, and biocompatibility, demonstrates considerable promise for clinical applications. However, due to the significant limitations in clinical applications caused by the biological inertness of PEEK, it should first be modified to meet clinical needs. Currently, the field of PEEK modifications is rapidly advancing, with a particular emphasis on enhancing its biological properties. Most of the previous reviews have separately discussed strategies like antibacterial, osteogenic, and angiogenic enhancements for PEEK. This review combines cross-domain insights to update and synthesize recent research on PEEK composites, focusing on advanced multi-component sustained release platforms that mimic postoperative biological processes. Such temporal alignment between material functionality and physiological healing phases demonstrates unprecedented potential for expanding PEEK's clinical versatility.
