[Digital orthopedics technology leads the new development direction of arthroplasty]

Digital orthopedics technology is a new interdisciplinary subject, known as the third technological wave in the field of orthopedics. The development direction of arthroplasty is focused on hoping to improve the long-term prognosis of patients by imitating more natural kinematics and optimizing implant positioning strategies. At present, various digital orthopedic technologies such as virtual reality technology, navigation assistance systems, and patient-specific instrumentation (PSI) and robot-assisted surgery in joint surgery are in full swing. In this article, relevant domestic and foreign literature were extensively reviewed and the author's own experiences were summarize, and the advantages, disadvantages, clinical efficacy and future prospects of the above-mentioned various technologies were evaluated too.
