The final, formatted version of the article will be published soon.

    Titanium, its alloys, and their surface modification technologies have consistently been subjects of great enthusiasm among orthopedic surgeons. Nevertheless, orthopedic infections-primarily attributed to the biologically inert surface of titanium alloys and their lack of intrinsic antibacterial properties-represent the second leading cause of implant failure in clinical practice. Surface micro-/nano-structured (MNS) modifications of titanium alloys have gained significant attention as a promising strategy to impart multifunctional biological properties to these materials. Such modifications promote osteogenesis, modulate immunity, and enhance antibacterial properties.Furthermore, the micro-and nano-structured surfaces can serve as carriers for drug delivery, further mitigating the risk of orthopedic infections. This review provides a comprehensive overview of recent advancements in anti-infection strategies for titanium alloys with MNS surfaces. It emphasizes strategies such as drug loading, anti-adhesion surfaces, and stimulus-response systems, providing important guidance for advancing next-generation anti-infection orthopedic implants.
