To understand the current status of orthopedic research in Japan, South Korea, and China.
Journals listed in the ‘‘Orthopedics’’ category of Science Citation Index Expanded subject categories were included. The PubMed and Web of Knowledge electronic databases were searched to identify scientific publications from the selected journals written by researchers from Japan, South Korea and China. A systematic analysis was conducted to analyze orthopedic research articles published in the three countries based on the number of articles, study design, impact factors (IFs) and citations. Furthermore, we also ranked the top 10 countries worldwide with the highest publications in the past 10 years. Additionally, we ranked the top 10 countries with the highest number of publications in the world in the past 10 years. Statistical analyses were performed using SPSS 20.0 software (SPSS Inc., Chicago, IL, United States), and statistical results are given in Tables and Figures. The Kruskal-Wallis test and the Mann-Whitney test were used to detect differences between countries. The tendency regarding the number of articles was analyzed by curvilinear regression. A two-tailed P < 0.05 was considered significant.
From 2012-2021, a total of 144518 articles were published in the 86 selected orthopedic journals. During this period, the number of worldwide published orthopedic articles has shown an annual increasing trend. A total of 27164 orthopedic research articles were published by Japan, South Korea and China during the past 10 years; 44.32% were from China, 32.98% were from Japan, and 22.70% were from South Korea. From 2012 to 2021, the annual number of articles markedly increased in each of the three countries. Over time, the worldwide share of articles increased substantially in South Korea (3.37% to 6.53%, P < 0.001) and China (5.29% to 9.61%, P < 0.001). However, the worldwide share of articles significantly decreased in Japan (5.22% to 3.80%, P < 0.001). The annual total IFs of articles from China were well above those of articles from Japan and South Korea (36597.69 vs 27244.48 vs 20657.83, P < 0.05). There was no significant difference among the articles in the top 10 high-IF orthopedics journals published from those three countries [South Korea (800) > China (787) > Japan (646), P > 0.05].
Over the past 10 years, China’s scientific publications in orthopedic journals have shown an increasing trend. Considering the relative scale of the populations, Japan and South Korea have outpaced China with respect to quality.
Core Tip: Our study was the first to systematically analyze and compare the scientific publication trends of orthopedic surgery studies over the past 10 years in three major East Asian countries–i.e., Japan, South Korea, and China–and to summarize the current status of orthopedic science research in these three countries, thus providing useful information for orthopedic science research.

Orthopedic disorders are a general health problem that affects people of all ages and demographic backgrounds. These disorders are a major burden for individuals, health systems, and social care systems, with indirect costs being the most dominant burden. In particular, the majority of the global burden of orthopedic disease occurs in low- and middle-income countries and is susceptible to neglect. China is the largest developing country in the world; it has more than 1.37 billion people, and it is facing the big challenge of reducing the burden of disease. For instance, more than 50000 hip or knee joint replacements are annually performed in China[1-3]. Researchers have progressively focused more attention on this situation and are now trying to advance the understanding, treatment and prevention of musculoskeletal disorders[4,5].
East Asia is an important subregion of Asia and is also the most dynamic region in the world. The countries in East Asia include Japan, North Korea, South Korea, Mongolia, and China. Japan is a world leader in fundamental scientific research[6]. South Korea is one of the new industrial economic countries as well as a leader in scientific research[7,8]. Due to the rapid socioeconomic development that has occurred in China, scientific and medical fields have undergone tremendous changes in the past decade[9,10]. Japan, South Korea and China are non-English-speaking countries that adhere to traditional East Asian cultural practices, and they are well-developed, developed and developing countries, respectively. Scientific publication provides a connection between the production and use of scientific knowledge and is a widely accepted method for evaluating public health and academic achievement. Nonetheless, little is known about the relative contributions of the three major East Asian countries to the field of orthopedics. The quantity and quality of scientific literature can be used to analyze the history and current status of science and technology and to forecast trends. Hence, it is crucial to accurately estimate global and regional productivity in ongoing orthopedic research. The present study was designed to investigate the characteristics and trends in orthopedic research studies from Japan, South Korea and China over the past 10 years.
This retrospective study investigated 86 journals from the ‘‘Orthopedics’’ category of the Science Citation Index Expanded for 2021[11]. Resources in this category include general orthopedics publications and specialized research on musculoskeletal disorders, spine diseases, injury, arthroplasty, arthroscopy, hand surgery, sport medicine, traumatology, foot and ankle surgery, connective tissue diseases, osteoarthritis and physical therapy. Based on the selection criteria, a total of 86 orthopedics journals were selected, and the journals included in the search are shown in Supple
The author's institutional affiliation was used to identify the country of the scientific publication. The publication type categories in the PubMed database were used to compile clinical trials, randomized controlled trials (RCTs), and case reports. In accordance with previous studies[12-14], four methods were used to evaluate publication quality. First, the annual total and average IFs were determined according to JCR 2021[15]. Second, the distribution and citation patterns of articles written by researchers from these three countries were analyzed using Reference Citation Analysis (https://www.referencecitationanalysis.com/)[17]. Third, we calculated the number of clinical trials, RCTs, systematic reviews/meta-analyses and case reports. Fourth, we quantified the articles published in the top 10 high-IF orthopedic journals and identified the top 10 popular orthopedic journals in the three countries based on the number of articles published in each journal. Moreover, we assessed global trends in orthopedic publications and ranked the top 10 countries with the highest number of publications worldwide over 10 years. Two reviewers (WC and XX) independently extracted the articles. Disagreements between the two reviewers were resolved by consulting a third reviewer (HJ).
A total of 144518 articles were published in 86 orthopedics journals from 2012 to 2021. The global number of annually published orthopedic research articles showed an increasing trend during the study period. The United States was the highest ranked country in terms of the number of published orthopedic research articles (39017 articles), followed by China (14939), Japan (11525), the United Kingdom (11203), Germany (10080), Canada (7887), South Korea (7664), France (7138), Australia (6849), and the Netherlands (5941). The top 10 countries in the world with the highest number of annual publications are shown in Table 1.

A total of 27164 articles from Japan, South Korea and China were published in the 86 selected journals between 2012 and 2021 (Figure 1). 44.32% (12040/27164) were from China, 32.98% (8959/27164) were from Japan, and 22.70% (6165/27164) were from South Korea (P < 0.05). From 2012 to 2021, the annual number of articles published in the orthopedic field increased noticeably in South Korea (459 to 899, annual rate of increase = 6.95%, R2 = 0.798, P < 0.001), China (552 to 2661, annual rate of increase= 17.03%, R2 = 0.823, P < 0.001) and Japan (622 to 1620, annual rate of increase = 10.05%, R2 = 0.728, P < 0.05) (Figure 2A).
The worldwide share of articles increased remarkably over time in South Korea (3.37% to 6.53%, annual rate of increase = 6.85%, R2 = 0.988, P < 0.001) and China (5.29% to 9.61%, annual rate of increase = 6.16%, R2 = 0.995, P < 0.001). However, the worldwide share of articles decreased dramatically in Japan (5.22% to 3.80%, annual rate of increase =-3.14%, R2 = 0.878, P < 0.001) (Figure 2B). In 2021, China accounted for 11.20% of all articles in the orthopedics field, followed by Japan (6.82%) and South Korea (3.78%) (P < 0.05).
Researchers from China published more clinical trials than researchers from Japan and South Korea [China (634) > South Korea (426) > Japan (330), all P values were less than 0.05] (Figure 3). Between 2012 and 2021, Chinese researchers published 512 RCTs, South Korean researchers published 353 RCTs (P < 0.05). Compared to China and South Korea, Japan had a distinctly higher number of case reports (P < 0.05) (Figure 3).
During the past 10 years, the annual total IFs were ranked in the following order: China, Japan and South Korea (36597.69 vs 27244.48 vs 20657.83, P < 0.05) (36597.69 vs 27244.48 vs 20657.83, P < 0.05). The annual total IFs of articles from China were markedly higher than those from South Korea. For the past 10 years, there were no discernible variations in the annual total IFs between Japan and the other two countries (P > 0.05). The average IFs of articles from Japan or China were significantly lower than those of articles from South Korea. (2.81 vs 2.94 vs 3.21; all P values were less than 0.05) (Figure 4). However, there was no significant difference in the average IF between Japan and China (P > 0.05).
Articles from China had the highest number of citations (164175 citations), followed by those from Japan (117323 citations) and South Korea (83118 citations). There was a significant difference in the number of citations between China and the two other countries (P < 0.001), but there was no statistically significant difference in the number of citations between Japan and South Korea (P > 0.05) (Figure 2C).
The top 10 high-IF orthopedic journals with 2642 articles from the three countries. Among them, 41.75% (1103/2642) were in the top three journals: Journal of Physiotherapy, Osteoarthritis and Cartilage, and American Journal of Sports Medicine. Researchers from Japan published 770 (29.14%) articles in the top 10 high-IF orthopedics journals, those from South Korea published 847 (32.06%) articles, and those from China published 1025 (38.80%) articles (Table 2).

The journals with the highest number of articles published by researchers from these three countries are shown in Table 3. Over the past 10 years, most of the orthopedic research studies from China were published in the Journal of Orthopaedic Surgery and Research (1680), most of the articles from Japan were published in the Journal of Orthopedic Science (1427), and most of the articles from South Korea were published in Clinics in Orthopedic Surgery (492). Spine, BMC Musculoskeletal Disorders appeared among the top 10 popular journals for all three countries.

To the best of our knowledge, this is the first study to investigate the characteristics of and trends in orthopedic studies from Japan, South Korea and China. The number of worldwide orthopedic publications showed an upward trend from 2012 to 2021. Unquestionably, the United States ranks first in the world in terms of total and annual number of orthopedic publications. Over the past 10 years, there has been a steady increase in the number of articles published each year in highly developed countries, including the United Kingdom, Japan, Germany and France[18,19]. Notably, there has been drastic growth in the annual number of articles published in China and Japan. Their articles disseminate a wealth of scientific knowledge and make significant contributions to the countries’ profound emphasis on academic research, as well as active global engagement. Therefore, these countries have contributed to the development of orthopedics over the past 10 years.
During the past 10 years, a considerable increase in the total number and percentage of articles in orthopedic journals from Japan has been observed. Despite substantial growth in the annual number of orthopedic research articles published in Japan (622 in 2012 to 1620 in 2021), the country’s worldwide share of articles decreased from 5.22% in 2012 to 3.80% in 2021. This decrease may be attributed to a decrease in government funding allocated for research endeavors[20]. Nevertheless, Japan still has a considerable international impact on scientific research and is a leader in the field of orthopedics. The large amount of research funding and the vast number of well-trained researchers might account for the objective reality that Japan has attained a continuously dominant position. Furthermore, Japan enjoys an efficient and competitive system of scientific research, which may be considered a reference model for some developing countries in Asia.
In the past 10 years, the annual number and worldwide share of orthopedic publications from South Korea have also increased (annual number: 459 in 2012 to 899 in 2021; worldwide share: 3.37% in 2012 to 6.53% in 2021). The rise of scientific research may be ascribed to the aging population. As the population progressively ages, there is a pronounced increase in the prevalence of orthopedic disorders[21]. In response, researchers have redirected their focus toward gaining a better understanding of this situation and advancing the treatment of orthopedic disorders. Consequently, South Korea has emerged as a noteworthy contributor to the development of orthopedic science, gradually gaining recognition for its prowess and innovative approaches.
There has been a strong positive trend in orthopedic publications from China. Our study suggests a 5-fold increase in the absolute number of articles from China in orthopedic journals (from 552 papers in 2012 to 2661 paper in 2021, P < 0.001), and the market share of articles in China has increased markedly (from 5.29% in 2012 to 9.61% in 2021, P < 0.001). In the orthopedics field, China’s scientific research has been growing rapidly in the past decade[14,18,19]. In 2013, articles originating in China (629) surpassed those originating in Japan (627) and South Korea (548). Between 2012 and 2021, researchers from China published 634 orthopedic clinical trials, outpacing those from South Korea (n = 426, P < 0.05) and Japan (n = 330, P < 0.05). Only 1083 RCTs were found among all 27164 articles originating in these three countries (Japan 218 vs South Korea 353 vs China 512; P < 0.05). RCTs are considered to be a higher grade of scientific evidence that influences health care policy. Thus, researchers in East Asia should prioritize more RCTs and consider these findings.
The average number of citations to articles in the publications is indicated by the IF. Although the IF has many limitations[22,23], it remains one of the optimal tools for assessing the relative significance of scientific studies. Researchers from South Korea made the most qualitative contributions to orthopedic research, as evidenced by the number of papers they published in high-IF journals and the highest annual average IFs. Researchers from South Korea published more articles in high-IF journals and had the highest annual average IFs, indicating that they contributed the majority to orthopedic research in terms of quality. Throughout the past 10 years, there has been steady growth in the total annual IF of articles originating from China. However, the annual average IFs still lagged behind South Korea. Undoubtedly, the quality of the articles and the international presence from China requires improvement. Citations are another valuable indication of article quality, revealing the extent to which the article has been accepted by other authors in the same field. In this study, we revealed that articles from China had a fairly high number of citations, followed by those from Japan and Korea. The average number of citations for Chinese studies ranked behind Japan and South Korea. In fact, newly published articles have less time to be cited, and thus, old articles of high quality are usually more often cited. In the past 3 years, China published 6042 articles, accounting for 50.18% (6042/12040) of the total number of articles published from 2012 to 2021, which could explain this phenomenon.
Regarding the orthopedic journals with a top-ten IF, researchers from China (1025) and South Korea (847) published more articles in these journals than researchers from Japan (770), but there was no significant difference among the three countries (P > 0.05). It should be noted that IF is not always the optimum parameter for identifying the quality of journals. Sometimes, a high IF represents a journal with high visibility, prestige, and influence. Researchers with well-designed studies tend to submit their articles to journals with these characteristics. In this study, spine and BMC Musculoskeletal Disorders were considered the most popular journals, ranking among the top 10 popular journals in the three countries. The most popular journals in this study were Spine and BMC Musculoskeletal Disorders, which were ranked among the top 10 most popular publications in each of the three nations. These two journals mainly publish high-quality clinical and basic research articles, which results in their widespread international influence. However, there were differences in the most popular journals for authors among the three countries. Researchers from Japan publish most in Journal of Orthopedic Science. This journal is the official journal of the Japanese Orthopedic Association and has a lengthy and illustrious history of publishing outstanding scientific papers in the field[24]. The top three popular journals for South Korea were Clinics in Orthopedic Surgery, Knee Surgery Sports Traumatology Arthroscopy and Arthroscopy-The Journal of Arthroscopic and Related Surgery, suggesting that arthroplasty surgery in South Korea is developing rapidly and has achieved great advances in recent years. On the other hand, the top three popular journals for China were Journal of Orthopaedic Surgery and Research, BMC Musculoskeletal Disorders and Orthopaedic Surgery, demonstrating that China has markedly improved its research in the field of orthopedic surgery during the past 10 years.
Orthopedic research in China is experiencing a period of immense growth, which is due to several factors. First, numerous newly established institutions and hospitals in China already conduct scientific research and surgical treatment in orthopedics, with recent advances in China’s economy[9,25,26]. Second, the continual development of international cooperation might benefit Chinese orthopedic researchers to strengthen their clinical orthopedic practice and research abilities[27-29]. Third, the number and IF of articles indexed in the SCIE database were recently regarded as important indicators to evaluate the performance and achievements of a researcher or an institution in China. Importantly, SCIE papers are tightly linked to authors' academic status, income, funding and other key benefits[30,31]. However, these policies seem to have resulted in an increase in the number of articles and not in their quality, as indicated by the current citation rates for Chinese-authored articles.
There are some limitations to this study. First, only 86 orthopedic journals included in the SCIE database were analyzed. There were some orthopedic research articles published in general medical journals that were not included in our study. Second, the JCR database was restricted to include studies published in English, which may lead to publication bias. For that reason, we may have neglected the contribution of non-English publications.
In summary, some useful information about scientific research in orthopedics is provided in this study. China has maintained an increasing trend of scientific publication in orthopedics journals over the past 10 years and has exceeded Japan and South Korea in some aspects of orthopedics publications. Given the relative size of the populations, China still lags behind Japan and South Korea in terms of quality. Chinese orthopedic researchers must improve their research activities and produce high-quality research.
Orthopedic research in East Asia has made significant strides over the past 10 years. However, the current status of orthopedic research in the three major East Asian countries of Japan, South Korea, and China remains uncertain.
To explore the current state of orthopedic research in Japan, South Korea, and China and provide informative findings in the field of orthopedic science.
To visualize the publication quantity, global share, publication types, impact factor (IF), and citation trends of orthopedic studies from Japan, South Korea, and China during the period of 2012-2021 and to analyze the developmental trends in orthopedic research in East Asia over the past decade.
According to the selection criteria, which include: (1) The journal was indexed in the PubMed database; and (2) the journal had IFs in accordance with the Journal Citation Reports for 2021, a total of 86 orthopedic journals were included. The PubMed and Web of Knowledge databases were searched from January 1, 2012, to December 31, 2021, to retrieve articles published in the selected 86 journals by researchers from Japan, South Korea, and China. The publication quantity, global share, publication types, IF, and citation patterns of these papers were then analyzed and visualized. Statistical analyses were performed using SPSS 20.0 software.
Between 2012 and 2021, a total of 27164 orthopedic studies were published by Japan, South Korea, and China, showing a steady increase over the years. Among them, 44.32% were from China, 32.98% were from Japan, and 22.70% were from South Korea. Over time, the global share of articles significantly increased in South Korea (from 3.37% to 6.53%, P < 0.001) and China (from 5.29% to 9.61%, P < 0.001), while it decreased significantly in Japan (from 5.22% to 3.80%, P < 0.001). The annual total IFs of articles from China were well above those of articles from Japan and South Korea (36597.69 vs 27244.48 vs 20657.83, P < 0.05). There was no significant difference in the number of top 10 high-IF orthopedics journals published among these three countries [South Korea (800) > China (787) > Japan (646), P > 0.05].
China's orthopedic publications have seen consistent growth in the past decade, but when considering their population scales, Japan and South Korea still outpace China with respect to quality.
The authors aim for this article to contribute toward the assessment and enhancement of academic productivity in orthopedic research in East Asia. In the future, it is imperative to foster stronger international cooperation and increase financial support for orthopedic research to produce a high level of evidence research and foster the sustained development of orthopedic research.
