A Bibliometric Analysis and Visualisation of Research Trends in Orthopaedic Implants

Several metals are used for orthopaedic implants. The bibliometric analysis had been conducted to understand the active authors, organizations, journals, and countries involved in the research domain of “orthopaedic implants”. All published articles related to “orthopaedic implants” from “Scopus”, were analyzed using the VOS viewer to develop analysis tables and visualization maps. This article had set the objective to consolidate the scientific literature regarding “orthopaedic implants” and also to find out the trends related to the same. The most active journals in this research domain were the Biomaterials. The most active country was the United States of America. The leading organization engaged in research regarding Orthopaedic implants was the IRCCS Rizzoli Orthopaedic Institute, Bologna of Italy. The most active authors who had made valuable contributions related to dental implants were Arciola C.R and Webster T.J.

Research Methodology
Scopus files had been used for this article. For the article selection, the Boolean used was TITLE (Orthopaedic implant) on 11/03/2021. All the tables in this paper were created by using Microsoft Excel and VOS Viewer. Grammarly was used for spelling and grammar checks. Mendeley was used for article review and citation. This paper had been inspired by bibliometric analysis in its presentation style, analysis, and methodology from the works (

Results and discussion 3.1 Results
This first round of search produced an outcome of 1836 documents, in 23 languages, out of which 1683 documents were in English. The classification of document categories is shown in Figure 1. For improving the quality of the analysis, we had selected only the peer-reviewed articles and all other documents had not been considered. Thus after using filters "Article" and "English" the second round search produced an outcome of 1089 English articles (both open access and others). This paper had used all English articles to conduct bibliometric analysis and visualization using VOS Viewer. The English research articles in this domain since 1961 had been shown in Figure 2.    In Co-occurrence analysis, we had used all keyword analyses, by keeping the minimum number of occurrences of a keyword as 100. This combination plotted the map of 23 thresholds, in three clusters. The overlay visualization of co-occurrence analysis of keywords has been shown in Figure 4.  Co-authorship analysis of the countries engaged in the research on "orthopaedic implants" had been shown in Figure 5. The overlay visualization map of co-authorship analysis plotted in Figure 5, points out the main countries with their strong co-authorship linkages and clusters involved.  The most active countries in this research domain were the United States of America with the highest number of publications, co-authorship links, and citations.
Link analysis and citation analysis were used to identify the most active journal in this research domain. We have taken the parameters of the minimum number of documents of a journal as one and the minimum number of citations of a journal as one for the link analysis and citation analysis. Highlights of the most active and relevant journals related to "orthopaedic implants" are shown in table 4. Table 4 shows the journal activity of this research domain through parameters of publication volume, citations, and co-authorship linkages. co-authorship links, and citations 40 From the above discussion regarding the bibliometric patterns in the research regarding orthopaedic implants, this research had observed a gradual increase in research interest regarding orthopaedic implants from the starting of the millennium and the momentum is going on positively. This points out the relevance and potential of this research domain (Refer to Figure 2). The most active authors in this research domain were Arciola C.R and Webster T.J. with the highest publication, co-authorship links; and citations respectively (Refer to table 1). The overlay analysis of top countries researching orthopaedic implantations indicates that the United States of America was the leading country relating to the highest number of publications citations, co-authorship links (Refer to figure 5). The top journals of this research domain were identified as the Biomaterials with the highest number of publications, citations, and links. From these wide sources of information, researchers can focus on top journals where they can identify the most relevant and highly cited articles regarding orthopaedic implants.

Conclusion
The orthopaedic implant was an interesting research domain and the most active journals related to this research domain were the Biomaterials. The most active country was the United States of America. The leading organization engaged in research regarding Orthopaedic implants was the IRCCS Rizzoli Orthopaedic Institute, Bologna of Italy. The most active authors who had made valuable contributions related to dental implants were Arciola C.
