Abstract:Based on the accelerating global aging process and the increasing prevalence of common and prevalent orthopedic disorders，artificial intelligence（AI），as a core technology in computer science，has penetrated into all processes of orthopedic medical care. AI's use in orthopedics will also to lead a new round of technological revolution and achieve breakthrough developments. This study comprehensively summarizes the innovative achievements and technological breakthroughs of AI technology from five perspectives—disease prevention，diagnosis，surgery，rehabilitation，and pharmaceutical development in orthopedic diseases，elaborating on the current application status and limitations of the technology. Special emphasis is placed on issues such as data security，algorithm credibility，and clinical translation，and corresponding solutions to these three core problems are proposed respectively. Combined with specific clinical transformation paths and research trajectory，the development prospects of multimodal fusion and cross -disciplinary collaboration are prospected. In the fields of precision diagnosis and treatment of fractures，robot-assisted surgery，and personalized rehabilitation，AI outperforms conventional clinical approaches. However，factors such as the lack of comprehensive database retrieval，large - scale clinical validation，and immature technology have hindered the large - scale application and implementation of AI. This article provides a systematic summary for the technological transformation and academic development of AI in orthopedics，and also looks ahead to new directions and prospects.
