![]() For the hospitals of underdeveloped and developing countries, the financial burden of purchase and maintenance costs most likely limits its development. Meanwhile, some influential factors may prevent the development of orthopedic robotics. Some reports found that robotic surgery is more accurate in orthopedic implant placement, results in less intraoperative radiation exposure, as well as postoperative bleeding and pain, and has a better prognosis compared with conventional freehand techniques. In recent years, robotic technology has matured gradually, with an increasing number of surgical robots obtaining approval from the Food and Drug Administration for clinical practice. Nonetheless, robotic techniques have promising applications in orthopedic surgery. Orthopedic robotics is a complex as well as extremely challenging technique and is involved in multidisciplinary research from design to clinical use. Orthopedic techniques are rapidly expanding, particularly in the technological revolution of deep learning, robotic surgery, virtual reality, and 3D printing. These findings may assist the scholars better understand the current status and research trends to guide future practice and directions. The present bibliometric study summarizes the clinical research of orthopedic robots on study type, sample size, type of surgery, robot information, surgical site, most popular keywords, most cited papers, journals, authors, institutions, and countries. Research on orthopedic robots were classified into two clusters by co-occurrence networks: spinal-related robotic surgery and joint-related robotic surgery. The top 20 most frequently used keywords were identified from 950 author keywords. Most studies were small sample populations of low-quality in this field. MAKO was the most widely used robot in hip and knee surgery and Mazor in spinal surgery. Fourteen types of robots were used, with the majority applied in knee and spinal surgery. The journal with the most related and influential publications on robotic orthopedic surgery was the Journal of Arthroplasty. The top 30 most cited papers list showed 29 publications to be cited on more than 40 occassions. The most productive scholars were Tian Wei and Mont Michael A, with 14 publications each. The institution with the most contributions was the Beijing Jishuitan Hospital in China ( n = 15). Global publications presented an increasing annual trend, with the United States found to have the largest number of publications and robotic companies active in the field ( n = 99), followed by China ( n = 38), and the United Kingdom ( n = 27). In total, 224 clinical studies met the included standards between 2000 to 2019. Visualizing data of bibliographic coupling, co-citation, and co-occurrence analysis were performed using VOSviewer. Subsequently, data were analyzed using bibliometrics. MethodsĪll relevant publications on the clinical use of robotic surgery in orthopedics were searched from the Web of Science database. The present study aimed to evaluate the status and trends of robotic orthopedic surgery in a clinical setting using bibliometrics.
