A Bibliometric Analysis and Visualisation of Research Trends in of Hip Implant

Innovations and advances in material engineering and surface engineering play a key role in developing modern, safe, durable, and biocompatible implants. The bibliometric analysis had been conducted to understand the active authors, organizations, journals, and countries involved in the research domain of “hip-implants”. All published articles related to “hipimplants” from “Scopus”, were Journal of Bone and Joint Surgery and Journal of Arthroplasty. The leading organization engaged in research regarding hip implants was the University of Leeds. The most active authors who had made valuable contributions related to the surface coating of implants were Jacobs J.J

This bibliometric analysis will be a useful platform for future researchers by realizing the top researchers, organizations, and countries involved in research regarding the hip-implants. This article is arranged into four sections. The first section is the introduction, followed by the discussion of the methodology by which the research was conducted. The third section deals with results and discussion. The fourth section deals with the conclusion. The following research objectives and research questions were framed for conducting bibliometric analysis systematically.

Research Objectives
a) To consolidate the literature regarding hip implants b) To find out the trends related to the research of hip implants 1.2 Research Questions a) Who are the active researchers working on hip implants? b) Which are the main organizations and countries working on hip implants? c) Which are the main journals related to hip implants?

Research Methodology
Scopus files had been used for this article. For the article selection, the Boolean used was TITLE-ABS (hip implants) on 27/02/2021. 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 (Farhat et

Results and discussion 3.1 Results
This first round of searches produced an outcome of 701documents, in eight languages, out of which 676 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 464English articles (both open access and others) and had been used to conduct bibliometric analysis and visualization using VOS Viewer. The English research articles in this domain since 1961had been shown in Figure  2.       Co-authorship analysis of the countries engaged in the research on "hip 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 country in this research domain was the United States of America, with the highest number of publications, citations, and co-authorship links respectively 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 "hip 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. From the above discussion regarding the bibliometric patterns in the research regarding hip implants, this research had observed a gradual increase in research interest in hip 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 Jacobs J.J with the highest publication, co-authorship, and citations respectively (Refer to table 1). The overlay analysis of top countries researching hip implants indicates that United States of America was the leading country relating to the highest number of publications, citations, and co-authorship links (Refer to figure 5). The top journals of this research domain were identified as the Journal of Arthroplasty and Journal of Bone and Joint Surgery. From these wide sources of information, researchers can focus on top journals where they can identify the most relevant and highly cited articles regarding hip implants.

Conclusion
Hip implants was an interesting research domain and the most active journals related to this research domain were the Journal of Bone and Joint Surgery and Journal of Arthroplasty. The leading organization engaged in research regarding hip implants was the University of Leeds. The most active authors who had made valuable contributions related to the surface coating of implants were Jacobs J.J. This research domain offers a new avenue for researchers and future research can be on innovations in hip implants.
