Arthroplasty and global research output: A bibliometric analysis

A Bibliometric Analysis of the 500 Most Cited Papers in Orthopaedic Oncology

BACKGROUND

Despite notable progress over time, broad insight into the scientific landscape of orthopaedic oncology is lacking. We conducted a bibliometric analysis of the 500 most cited papers in the field.

METHODS

We searched the Science Citation Index Expanded database of the Web of Science Core Collection to find the 500 most cited articles in the field.

RESULTS

Citation count ranged from 81 to 1,808. Articles were published from 1965 to 2018. Over half of all articles were published in the United States (53.6%). The 2000s was the most productive decade with 170 (34%) articles. All articles were written in English and were published across 29 journals. Female participation as first authors significantly increased from the 1960s to the 2010s (0% vs 14.6%, P = 0.0434). Similarly, female involvement as senior authors grew from the 1960s to the 2010s (0% vs 12.2%, P = 0.0607). Primary bone sarcomas were the most cited topic among articles from the 1970s to the 1980s. From studies produced in the 1990s up until the 2010s, reconstruction procedures were the most cited topic.

CONCLUSION

Trends over the years have resulted in an emphasis on a surgical technique. Notable progress has been made regarding gender diversity, yet disparities still exist.

Comparison of the scientific performance in hip and knee arthroplasty between the leading continents

Background

Scientific progress in the field of knee and hip arthroplasty has enabled the preservation of mobility and quality of life in the case of patients with many primary degenerative and (post-) traumatic joint diseases. This comparative study aims to investigate differences in scientific performance between the leading continents in the field of hip and knee arthroplasty.

Methods

Using specific search terms all studies published by the scientific leading continents Europe, North America, Asia and Oceania listed in the Web of Science databases were included. All identified publications were analysed and comparative conclusions were drawn regarding the qualitative and quantitative scientific merit of each continent.

Results

Europe, followed by North America, Asia, and Oceania, had the highest overall number of publications in the field of arthroplasty. Since 2000, there has been a strong increase in knee arthroplasty publication rate, particular pronounced in Asia. Studies performed and published in North America and those on knee arthroplasty received the highest number of fundings. Publications regarding hip arthroplasty achieved the highest average citation rate. In contradistinction to the others, in North America most funding was provided by private agencies.

Conclusion

Although Europe showed the highest total number of publications, authors and institutions, arthroplasty research from North America received greater scientific attention and financial support. Measured by citations, publications on hip arthroplasty attained higher scientific interest and studies on knee arthroplasty received higher economic affection.

Changes Over a Decade in Patient-Reported Outcome Measures and Minimal Clinically Important Difference Reporting in Total Joint Arthroplasty

Background

When used appropriately, the minimal clinically important difference (MCID) provides a powerful tool for identifying meaningful improvements brought about by a given treatment, offering more clinically relevant information than frequentist statistical analysis. However, recent studies have shown inconsistent derivation methods and use of MCIDs. The goal of this study was to report the rate of patient-reported outcome measures (PROMs) and MCIDs use in the literature and assess how this rate has changed over time.

Methods

All articles published in 2010 and 2020 reporting on total hip arthroplasty or total knee arthroplasty in The Journal of Clinical Orthopaedics and Related Research, The Journal of Bone and Joint Surgery, and The Journal of Arthroplasty were reviewed. In each reviewed article, every reported PROM and, if present, its corresponding MCID was recorded. These data were used to calculate the rate of reporting of each PROM and MCID.

Results

While the total number of articles on total hip arthroplasty and total knee arthroplasty reporting PROMs increased over time, the proportion of articles reporting PROMs decreased from 49.8% (131/263) in 2010 to 35.5% (194/546) in 2020 (P = .011). Of these articles that report PROMs, the proportion of articles reporting any MCID increased from 2.3% (3/131) in 2010 to 16.5% (32/194) in 2020 (P = .002).

Conclusions

The rate of reporting of MCIDs among articles relating to total hip arthroplasty and total knee arthroplasty that report PROMs has increased significantly between 2010 and 2020 but remains low. Continued emphasis on appropriate inclusion and value of MCIDs when PROMS are reported in clinical outcomes studies is needed.

A scientometric analysis of India's publications in arthroplasty in the last two decades from the SCOPUS database

Objectives

This study evaluates the publication output of the Indian authors on the topic of Arthroplasty research from 2002 to 2021, using bibliometric methods.

Methods

The Indian publications as listed in the Scopus database were identified by using "Arthroplasty" or "Joint Replacement" in the keyword ("Key") tag.

Results

India contributed 872 publications on Arthroplasty research, constituting a 1.36% share of global output, in the last two decades. Knee Arthroplasty accounted for the largest share (52.4%) in India's output, followed by Hip (35.7%) and others. 841 authors from 413 organizations participated unevenly in the research on this topic, with IISc-Bangalore contributing the largest number of publications (97), followed by Indraprastha Apollo Hospitals (46), Breach Candy Hospital, Bombay(40), and PGIMER, Chandigarh(38). R. Malhotra contributed the largest number of publications (55), followed by R. Vaishya (35 papers) and G.M. Shetty (23 papers). S. Bhan (31.0 and 3.17), A.B. Mullaji (30,13 and 3.08), N.P. Jain (25.75 and 2.63) and H.Pandit (21.88 and 2.24) registered the highest CPP & RCI. The journals which published the highest number of Arthroplasty articles were the Journal of Arthroplasty (123), followed by the Journal of Clinical Orthopaedics & Trauma (50) and International Orthopaedics (32).

Conclusion

India's contribution in the field of Arthroplasty-related publication is still low on a global platform, however, has shown a positive and increasing trend in the last two decades. The maximum publications were related to knee and hip arthroplasty and were from institutions in the major Indian cities of Delhi and Mumbai. More international and multicentric collaboration and external funding may help improve the number of arthroplasty publications in the future.

Global Publication Trends and Research Hotspots of Revision Hip and Knee Arthroplasty: A 21-Year Bibliometric Approach

BACKGROUND

As the number of primary hip and knee arthroplasties increases, revision cases correspondingly demonstrate high relative growth, gaining increasing attention. The present research aimed to investigate subject characteristics in revision hip and knee arthroplasty (RHKA) research using a bibliometric approach.

METHODS

Publications related to RHKA from 2000 to 2020 were searched in the Web of Science database. WPS Office, CiteSpace, VOSviewer, and Bibliometrix were used to analyze the results.

RESULTS

Bibliometric analysis revealed 3290 records. Fifty-nine countries published manuscripts on RHKA. The United States contributed most and also had the highest number of international collaborations. The most relevant institution was the Mayo Clinic. Berry DJ and Parvizi J were the most productive and academic influential authors in RHKA, respectively. The most productive journal was the Journal of Arthroplasty. Co-occurrence analysis demonstrated "infection" to be the trend in RHKA. Thematic analysis displayed 16 keywords in hip arthroplasty and 14 keywords in knee arthroplasty.

CONCLUSION

The present study observed an increasing trend of research papers in RHKA. Institutions and scholars from the United States were found to dominate the field. Periprosthetic joint infection was likely a potential development trend and hotspot of RHKA.

Gender Disparity in the Citation of Surgical Research

BACKGROUND

Women surgeons face numerous barriers to career advancement. Inequitable citation of surgical literature may represent a contributing factor to gender disparities in academic surgery.

STUDY DESIGN

This was a cross-sectional analysis of publications from 50 top-ranking surgery journals in 2017 and 2018, as defined by the 2019 InCites Journal Citation Reports. The citation rate of publications by women vs men first authors was compared. Similarly, the citation rate of publications by men vs women last authors was also compared. Adjusted regression analyses of citation rates accounted for the time interval since publication as well as the journal within which the article was published, among other potential confounding factors.

RESULTS

A total of 19,084 publications from 48 surgery journals with a median (interquartile range) of 8 (4 to 15) citations contributing to a median (interquartile range) Journal Impact Factor of 4.0 (3.4 to 4.6) were analyzed. Compared with man-first author publications, woman-first author publications demonstrated a 9% lower citation rate (incidence rate ratio 0.91, p < 0.001). Similarly, compared with publications by man-last authors, woman-last author publications demonstrated a 4% lower citation rate (incidence rate ratio 0.96, p = 0.03). These associations persisted after multivariable adjustment for additional confounding factors, however, not on sensitivity analysis of 24 of the highest-ranking journals.

CONCLUSIONS

Among top-tier surgical journals, publications by women-first and -last authors were less cited compared with publications by men-first and -last authors, but not among the highest-tier surgical journals. Gender bias may exist in the citation of surgical research, contributing to gender disparities in academic surgery.

Bibliometric and Altmetric Analyses of Publication Activity in the Field of Behcet's Disease in 2010-2019

BACKGROUND

Behcet's disease (BD) is a systemic vasculitis accompanied by oral-genital ulcers, ocular, cerebral, and gastrointestinal disorders. The aim of this study was to evaluate BD articles published between 2010-2019 bibliometrically and to provide up-to-date data. A secondary aim was to present a different perspective using altmetric assessments.

METHODS

This bibliometric and altmetric research was performed with data obtained from the Web of Science database. The key terms "Behcet's disease," "Behcet's syndrome," and "Behcet" were used for listing the articles. The number of articles, citation data, and active countries were determined. Trend and correlation analyses were performed. Altmetric attention scores (AASs) and Mendeley readers count (MRC) of the articles were acquired for the altmetric evaluations.

RESULTS

A total of 5,201 articles were listed. After the exclusion criteria, a total of 2,163 articles were obtained for further analysis. A significant and increasing trend was detected in the number of articles from 2010 to 2019 (P < 0.001). Turkey (28.24%), China (9.57%), South Korea (9.20%), Japan (6.38%), and Italy (5.64%) were the five most productive countries. France, the United States and, the United Kingdom were the top three countries in respect of the average number of citations per article. A weak significant correlation was detected between the number of citations and AAS (P < 0.001). The number of citations was significantly and strongly correlated with the MRC (P < 0.001).

CONCLUSION

An increasing trend was found in BD research productivity. Although the Silk Road countries were prominent in the number of articles, a similar ranking was not valid for the average number of citations per article.

Ankylosing spondylitis rehabilitation publications and the global productivity: a Web of Science-based bibliometric analysis (2000-2019)

Rehabilitation programs have an important place in the treatment of ankylosing spondylitis (AS), but there is no comprehensive bibliometric research that assesses publications on AS rehabilitation in a holistic way. The aim of this study was to investigate the quantity and quality of articles related to AS rehabilitation and to reveal the features of global productivity in this topic. This bibliometric study was conducted utilizing the Web of Science (WoS) database with the keywords 'ankylosing spondylitis rehabilitation', 'ankylosing spondylitis exercise', 'ankylosing spondylitis physical therapy' and 'ankylosing spondylitis physiotherapy'. The number of articles, citations, and main active countries were determined and trend analyses were performed. A total of 792 articles were reviewed. The articles originated from 51 different countries, 22 of which met the main active country criteria. A significant increase trend was detected in the number of articles between 2000 and 2019 (p < 0.001). The five most productive countries were Germany (n = 111; 14.02%), Turkey (n = 98; 12.37%), the United States (n = 71; 8.96%), the United Kingdom (n = 53; 6.69%) and the Netherlands (n = 53; 6.69%). The highest values in number of articles per million population were calculated in Norway, the Netherlands and Austria, respectively. In the analysis according to GDP, Norway, the Netherlands and Turkey were ranked as the first three. The top three countries for the average citation count were France, Netherlands and Germany. This bibliometric study can be considered as an assessment and summary of worldwide scientific production on AS rehabilitation. The data demonstrate an increasing trend in research productivity since 2000. European countries were seen to be at the forefront both quantitatively and qualitatively in this area.

Publication activity in the field of Sjögren's syndrome: a ten-year Web of Science based analysis

Bibliometric analysis is widely utilized to evaluate global research productivity in different research topics. However, to date, there has been no assessment of worldwide research productivity associated with Sjögren's syndrome. Therefore, the aim of this study was to evaluate the global research productivity in the field of Sjögren's syndrome using bibliometric analysis. The Web of Science database was scanned with the search terms 'Sjögren's syndrome' and 'Sjögren syndrome' for publications in the period 2010-2019. Original articles and reviews were selected for analysis. The most active countries were determined, and the number of articles, citations, research productivity adjusted by population and gross domestic product were analyzed. A total of 3856 articles were identified from 65 different countries. A statistically significant trend was observed in the direction of increase (in terms of the number of articles; from 282 to 461) in the 10-year period. A total of 3004 (77.90%) articles were from high-income countries. The five most productive countries were the United States (n = 714, 18.51%), China (n = 428, 11.09%), Japan (n = 308, 7.98%), Italy (n = 299, 7.75%) and France (n = 249, 6.45%). When the number of articles was adjusted according to population, Norway was the most productive country, followed by Greece and the Netherlands. In analysis according to gross domestic product, Greece was the leading country, followed by Norway and the Netherlands. The results of this study demonstrated a remarkable growth in global research productivity on Sjögren's syndrome between 2010 and 2019. More than three quarters of the articles were from high-income countries. When population and gross domestic product were considered, relatively small European countries came to the fore.
