Trends of arthroscopy publications in PubMed and Scopus

Trends in Meniscus-Related Publications in PubMed Since 1928: A Bibliometric Study

Background

As information on the meniscus accumulates in PubMed, it is possible to evaluate the trends in research on the topic over time.

Purpose

To evaluate the major trends in meniscus-related publications in PubMed from the earliest publication to the present day.

Study Design

Cross-sectional study.

Methods

PubMed was searched on January 3, 2023, using the search strategy "menisc *"[All Fields] AND ("knee"[MeSH Terms] OR "knee"[All Fields] OR "knee joint"[MeSH Terms] OR ("knee"[All Fields] AND "joint"[All Fields]) OR "knee joint"[All Fields]) AND 1900/01/01:2022/12/31[Date - Publication]. This retrieved 15,569 human and animal studies. We determined the top 10 meniscus-related publications in terms of overall citations and citations per year, as well as the top 10 authors, journals, countries, and institutions of cited publications on the meniscus. In addition, we performed word-cloud analyses based on meniscus-related terms from different periods (before 1981, before 2000, after 2005, and in the past 5 years [2018-2022]), including the year of first appearance and the number of publications featured.

Results

Since the first recorded publication on the meniscus in 1928, there was a steady growth in the number of articles until 2005, when there was an upsurge in publications from 254 in 2005 to 955 in 2022. Noyes was the author with the most citations (n = 3314), and a 2006 study by Caplan and Dennis had the most citations per year (n = 125). Arthroscopy published the most articles on the meniscus with 1118, whereas the Journal of Cellular Biochemistry had the most citations per article with 125.69. The most published countries and institutes were the United States and the Hospital for Special Surgery, respectively. Word-cloud analysis of article titles showed that "meniscectomy" had become less prominent, and "root,""ramp,""transplantation," and "slope" had become more prominent.

Conclusion

There has been an upsurge in publications on the meniscus since 2005, with word-cloud analysis indicating shifting interests in meniscus-related research.

Journal metrics of the top-ranked Orthopaedic, Medical, and Surgical journals - A cross-sectional, comparative study

PURPOSE

In academic publishing, research metrics play a crucial role in assessing the scientific impact and performance of the published literature, as well as of the journals in which they are published. Several journal-level metrics (JLM) such as the h-index of the analysed journals, total citations, total documents, citable documents, references and external citations per document are considered crucial indicators of the importance and reputation of the journals. We hypothesize that journals in the field of Medicine receive more citations than those in Surgical journals like Orthopaedic surgery, and hence have better JLM. This study aims to to assess and compare the JLM of Medical and Surgical journals between two time zones 2017-2019 vs. 2020-2022, i.e., pre and post-COVID-19 pandemic period.

METHODS

A cross-sectional bibliometric analysis of the top-ranked Orthopaedic, Medical, and Surgical journals was undertaken based on traditional JLM, using the SCImago database from 2017 to 2022. Our analysis focused on identifying trends in the h-index of the analysed journals, total citations, total documents, citable documents, references and external citations per document.

RESULTS

Overall Medical journals were found to have higher JLM than the Surgical and Orthopaedic journals. The h-index of Surgical journals, Medical journals and Orthopaedic journals were comparable between the two periods (pre and -post-COVID-19 pandemic); Total Cites (3 years), total documents (2017), total documents (3 years), total references, and citable documents (3 years) of Surgical journals, Medical journals and Orthopaedic journals were significantly higher in the period 2020-2022.

CONCLUSION

There has been a steady increase in the number of publications from post COVID-19 period. Medical journals have higher JLM than Surgical and Orthopaedic journals. Journal of Bone and Joint Surgery (Am), Annals of Surgery and Diabetes Care were the most published journals in Orthopaedics, General Surgery and Medicine-related topics respectively.

Arthroscopy in India Through the Medicolegal Lens: A Comprehensive Review

Introduction

With the increasing number of Arthroscopic surgeries, comes with it, the undesirable problem of litigation associated with it. Arthroscopy does possess certain unique aspects which need to be understood from the legal point of view as well.

Materials and Methods

We obtained information on specific medico-legal cases involving arthroscopy from books and websites containing collections of medico-legal judgments in Indian legal courts, consumer dispute redressal forums at the state and national levels, and state medical councils..

Results

We assimilated and analysed all this information, combined it with our experience in the field of medical law, and have provided practical, enforceable ways to decrease the medicolegal risk for arthroscopy surgeons.

Conclusion

This review provides a comprehensive overview of pressing issues in relation to the medicolegal aspects of arthroscopic surgery.

Borderline Dysplastic Hips Undergoing Hip Arthroscopy Achieve Equivalent Patient Reported Outcomes When Compared With Hips With Normal Acetabular Coverage: A Systematic Review and Meta-Analysis

PURPOSE

To systematically review and meta-analyze studies reporting lateral center edge angle as it relates to patient-reported outcome (PRO) measures and clinically notable outcome assessments for patients undergoing hip arthroscopy for femoroacetabular impingement syndrome or labral pathology with borderline dysplastic hips (BDH).

METHODS

PubMed, EMBASE, and the Web of Science Core Collection databases were queried for articles evaluating lateral center edge angle as a predictor of PRO after hip arthroscopy. Articles were eligible for meta-analysis if they compared PROs measures between patients with normal acetabular coverage and borderline dysplasia and were at least level III evidence. Continuous random-effects models with standardized mean differences were used to compare postoperative Hip Outcome Score-Activities of Daily Living and sports subscales, modified Harris Hip Score, international Hip Outcome Tool scores, Satisfaction, and Visual Analog Scale Pain scores between normal coverage and borderline dysplastic groups.

RESULTS

Overall, 989 hips undergoing arthroscopy from six investigations were included in this meta-analysis, including 315 borderline dysplastic subjects (mean age 27.5 years) and 674 subjects with normal coverage (mean age 26.9 years). Borderline dysplastic and normal coverage cohorts were followed for an average of 37.0 and 36.8 months, respectively. Postoperative PRO measures (Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports Subscale, modified Harris Hip Score, international Hip Outcome Tool-12, Satisfaction, and Visual Analog Scale Pain) collected approximately three years after hip arthroscopy were not markedly different between subjects with BDH when compared with patients with normal coverage.

CONCLUSIONS

In a meta-analysis of the available literature, patients with BDH are able to equally reach statistically similar clinical outcomes after isolated hip arthroscopy as compared with control subjects without dysplasia at short-term follow-up. A BDH should not be considered a contraindication to hip arthroscopy when optimal PRO achievement is the goal.

LEVEL OF EVIDENCE

Level III, Systematic Review and Meta-Analysis.

Research on artificial intelligence in shoulder and elbow surgery is increasing

Background

Total health care spending in the United States is increasing. In order to improve our delivery of high-quality, patient-centric, and cost-effective care, artificial intelligence (AI) and its subsets are being increasingly explored and utilized in medicine. Applications of AI in orthopedic surgery, including shoulder and elbow surgery, are being actively studied and have stirred much discussion. However, the trends of research on AI applications in shoulder and elbow surgery have not yet been quantified. Thus, the purpose of this study is to explore the general trends of research in applying AI to shoulder and elbow surgery and to examine characteristics of these research publications.

Methods

A literature search was conducted using PubMed for all articles published between January 1, 2000 and May 12, 2022. The primary search query used was as follows: (shoulder) and (AI OR machine learning OR deep learning OR neural networks). Exclusion criteria were as follows: (1) not pertinent to orthopedic surgeons (2) not pertaining to shoulder or elbow surgery, and (3) not pertaining to AI, machine learning, and deep learning. Selected articles in high-impact and relevant orthopedic journals were further characterized and analyzed.

Results

The annual number of articles increased from 1 article in 2006 to 24 articles in 2021. There was a 4-fold increase in publications between 2019 and 2021, and a 6-fold increase between 2018 and 2021. The average number of publications per year increased exponentially from 2010 to 2021 (R2 = 0.608; P = .003). The three journals with the most publications were Journal of Shoulder and Elbow Surgery (12), followed by Arthroscopy (2), and Clinical Orthopaedics and Related Research (2).

Conclusion

This study provides quantitative evidence for the first time that publications applying AI and its subsets to shoulder and elbow surgery are growing exponentially since the year 2010, with the most rapid growth beginning between the years of 2019 and 2020.

Past, Present and Future of Arthroscopic Research: A Scientometric Analysis of Research Frontiers in Arthroscopy

PURPOSE

Active research in arthroscopy in all its domains has been transcending into evidence-backed clinical practice over years. A look-back at the research developments in arthroscopy using scientometry for the past thirty years will help the researchers identify what has been investigated so far, and what needs to be done in the future.

METHODS

We used the Web of Science-core collection database as the source for data retrieval. We used CiteSpace (5.7.R1) for scientometric and visualization analysis Visualization of the structure, regularity, and distribution of research domains in the arthroscopy was done with the analysis of the article co-citation data to mine the knowledge clustering and citation space distribution. We also analyzed the co-occurrence between the additional research units such as cooperation among authors, institutions, and countries in the field of arthroscopy.

RESULTS

We recovered 383 RCTs and 11,853 non-RCT articles in the field of arthroscopy from the global literature of 15,766 arthroscopy-related publications from 1990 to 2019. Research co-operation group with the top contribution to the arthroscopic literature was from BG Domb, MJ Philippon, and SJ Nho for non-RCT articles and Casati A, Pluta A, and Lund B for RCTs. Weaker collaboration exists among the institutions globally, but the network of domestic institutions seemed stronger in co-institution analysis. USA and England have been the pioneers in research particularly the RCTs. The current hotspots were around the outcome analysis, particularly in the knee and shoulder pathologies. In the hip the main area of focus was the Femoro-Acetabular Impingement (FAI). The other areas of arthroscopy remain relatively less explored.

CONCLUSIONS

Research in arthroscopy is rapidly progressing. Poor international collaboration, the concentration of research only in certain areas of arthroscopy, and conduction of most RCTs only by certain institutes seem to be gross problems in arthroscopic research. Setting up of an International authoritative body for arthroscopic research is the way forward for arthroscopy.
