Long-term and stable fixation of implants is one of the most important points for a successful orthopedic surgery in the field of endoprosthesis. Osseointegration (OI), functional connection between bone and implants, is considered as a pivotal process of cementless implant fixation and integration, respectively. OI is affected by various factors of which the property of implants is of high significance. The modification of implants surface for better OI has raised increasing attention in modern orthopedic medicine. Here, the process of OI and the interactions between implants and ambient bone tissues were emblazed. The knowledge regarding the contemporary surface modification strategies was systematically analyzed and reviewed, including materials used for the fabrication of implants, advanced modification techniques, and key factors in the design of porous implants structure. We discussed the superiority of current surface modification programs and concluded that the problems remain to be solved. The primary intention of this systematic review is to provide comprehensive reference information and an extensive overview for better fabrication and design of orthopedic implants.
