In addition, scientific journals across the world have studied the impact of COVID-19 on trauma and orthopaedics. METHODS: A cross-sectional, bibliometric analysis of the literature was undertaken on COVID-19 related articles from three Pubmed and Scopus threeindexed orthopaedic journals from India, namely, Indian Journal of Orthopaedics(IJO),Journal of Clinical Orthopaedics and Trauma(JCOT), and Journal of Orthopaedics(JOO), in May 2021. All the article types and study designs were included for this review. The authors, institutions, countries, keywords, and co-authorship mapping were studied. RESULTS: A total of 112 COVID-19 related documents were retrieved. Period of these publications was from 2(nd) April 2020 to 31(st) May 2021. Vaishya R. (n = 16) was the most cited author, and Indraprastha Apollo Hospitals (n = 16) was the most cited research Institution. India led the list of countries in academic publication output. On keyword mapping, telemedicine was the most prominent Medical Subject Headings (MeSH) search word. CONCLUSION: The Indian orthopedic journals have addressed the impact of COVID-19 on orthopaedic practice in India and aborad whilst continuing to publish knowledge about basic science and clinical orthopaedic research studies. The JCOT has outperformed and become the most leading orthopaedic journal from India during the pandemic. COVID -19 articles have been fast tracked, open accessed and attracted more citations in reduced duration of time compared to non-COVID-19 papers. disease has thus resulted [5] [6] [7] [8] . The impact of COVID-19 on different facets of trauma and orthopaedics speciality and services have been published widely. For example, challenges and strategies to manage urgent orthopaedic conditions, suspension of elective orthopaedic surgery, innovative ways to provide continuity of patient care, and orthopaedic training have been highlighted [9] [10] [11] [12] . Bibliometric analysis of publications on the effect of COVID-19 in trauma and orthopaedics has observed that during the initial three months from the onset of pandemic, there was an unprecedented increase in the number of publications on COVID-19 worldwide [13] . We have aimed to analyse the trend of COVID-19 related articles from Published papers and articles were searched via a topic search (title/article) of COVID-19 on the databases of PubMed and Scopus on 31stMay 2021. Only articles with a focus on COVID-19 in the Pubmed and Scopus indexed orthopaedic journals from India, namely Indian Journal of Orthopaedics (IJO), Journal of Clinical Orthopaedics and Trauma (JCOT), and Journal of Orthopaedics (JOO), were included. Only the documents in the English language were considered for this study. Two authors (MP and VKJ) independently performed article selection and data extraction. Differences in opinion were settled by the most senior author, RV. To retrieve all the COVID-19 related papers published in IJO, JCOT, and JOO from the Table 1 . J o u r n a l P r e -p r o o f Data regarding the top authors, institutions, and countries from which the COVID-19 related papers were published in individual journals were extracted from the Scopus database, and relevant graphics were generated using Microsoft Excel for Mac(2016). Articles citing these papers from Indian journals were also analysed for each journal separately, especially journals and countries citing COVID-19 papers from each of these Indian orthopaedic Journals. The bibliographic data was imported in VOSviewer (Leiden University, Sweden) for Mac version 1.6.16 for generating keyword and co-authorship maps. The same was done for articles citing COVID-19 papers from Indian orthopaedic journals. Finally, a similar analysis was performed on the combined set of COVID -19 related articles from the three Indian orthopaedic journals. We also performed a correlation analysis (Karl Pearson correlation coefficient) between no of citations, Altmetric score, and level of evidence (LOE). If the coefficient value lay between ± 0.50 and ± 1, then it was considered strong correlation, moderate if it lay between ± 0.30 and ± 0.49, low if the value lay below + 0.29, and P<0.05 was considered significant. No patients were involved in this study. The current submitted article is not a clinical study involving any human subjects, and ethical approval was not applicable. The top cited COVID-19 papers are depicted in Table 2 , along with citations received in 2020 and 2021. h-index was defined as the top n papers in the set which had received at least n citations, and these papers can be considered to constitute the h core for COVID-19 papers in Indian orthopaedic journals. This figure was 12 overall, with ten papers from JCOT and one each from IJO and JOO. Therefore, the h-index was overall, and accordingly, papers are mentioned in Table 2 . Top cited papers (at least 10) in individual journals are depicted in Table 3 Figure 3A . Telemedicine, rapid response team, orthopaedic surgeon, trauma, and aged were the prominent keywords. Keyword map for journals citing these papers is shown in Figure 3B , which shows COVID-19, SARS-CoV-2, beta coronavirus, adult, orthopaedic surgery, and review as prominent keywords. Co-authorship map of all journals is depicted in Figure 4 March 2020. The focus of the articles was to provide knowledge, challenges, and valuable experience during and after the COVID-19 pandemic. At the beginning of the pandemic, while limited information was available on COVID-19; majority of the papers were opinion pieces, editorials, guidelines, and commentaries. The first paper published in JCOT was in early April 2020 and was a rapid review and recommendations for Musculoskeltal and allied heath personnel [14] . Thereafter, numerous articles were published. Publications in the IJO started in mid-April 2020. Predominantly these were editorials and recommendations to deal with COVID-19, and orthopaedic management of patients as a consequence of the disease [15] . In contrast to the above two journals, the original articles based on patients' outcomes were published earlier in the JOO. [12 and 19,20] . Telemedicine uses have also influenced the field of trauma and orthopaedics, its evolving role in the management of musculoskeletal conditions during COVID-19 thus, have been highlighted increasingly in articles submitted to these journals. InVOS viewer, a minimum threshold was used for mapping networks and therefore, not all items could be highlighted. Co-authorship mapping [21] has been included in bibliometric analysis because of its descriptive and synthetic power to describe the evolution of research [22] . This mapping indicates groups of authors involved in COVID-19 related manuscript work amidst the pandemic and their linkages. There appears to be a link between co-authorship and scientific impactcitation of published articles [23, 24] . Experience, author degree, and seniority in a particular field of medicine have both cognitive and reputation advantages to influence the paper's impact [25, 26] . This is evident from the main author groupings with senior authors in this study. The VOSviewer, is a devoted software tool for constructing and visualizing bibliometric networks. [27] [28] [29] . In this study, it was used for the analysis of the networking amongst the authors and also to generate the knowledge maps of keywords, which in turn indicates prominent areas of orthopaedic research related to the COVID-19 pandemic, as published in Indian Journals. We have analysed the trend of COVID-19 related articles during the last two years pertaining only to the PubMed and Scopus indexed Indian orthopaedic journals and not from the whole spectrum of orthopaedic journalist output from the subcontinent. However, these represent the impactful journalistic content from India and their popularity amongst the readerships. Therefore, it may be interesting to assess these parameters compared with similar leading journals across the world.Secondly, we have used the free search facility available on Scopus, and a further Altmetric analysis requires a subscription.
