Abstract With the improvement of implant design and expansion application scenarios, orthopedic implants have become a common surgical option for treating fractures end‐stage osteoarthritis. Their goal is rapidly forming long‐term stable osseointegration. However, this fixation effect limited by surface characteristics peri‐implant bone tissue activity. Therefore, review summarizes strategies interface engineering (osteogenic peptides, growth factors, metal ions) treatment methods (porous nanotubes, hydrogel embedding, other load‐release systems) through research on its biological mechanism, paving way to achieve adaptation both coordination between different strategies. transition osseointegration stage, demonstrated varying therapeutic effects. Especially, activity osteoblasts runs almost entire process osseointegration, their physiological activities play dominant role in formation. Furthermore, diseases impacting metabolism exacerbate difficulty achieving This aims assist future improve implant‐bone fixation, promote fracture healing, enhance post‐implantation recovery.
