Abstract
BackgroundPeriprosthetic joint infection (PJI) is the most serious complication of joint replacement surgery. Further comorbidities include bedsore, deep vein thrombosis, reinfection, or even death. An increasing number of researchers are focusing on this challenging complication. The aim of the present study was to estimate global PJI research based on bibliometrics from meta-analysis studies.MethodsA database search was performed in PubMed, Scopus, and Web of Science. Relevant studies were assessed using the bibliometric analysis.ResultsA total of 117 articles were included. The most relevant literature on PJI was found on Scopus. China made the highest contributions to global research, followed by the USA and the UK. The institution with the most contributions was the University of Bristol. The journal with the highest number of publications was The Journal of Arthroplasty, whereas the Journal of Clinical Medicine had the shortest acceptance time. Furthermore, the top three frequently used databases were Embase, MEDLINE, and Cochrane. The most frequent number of authors in meta-analysis studies was four. Most studies focused on the periprosthetic hip and knee. The alpha-defensin diagnostic test, preventive measures on antibiotics use, and risk factors of intra-articular steroid injections were the most popular topic in recent years.ConclusionBased on the results of the present study, we found that there was no single database that covered all relevant articles; the optimal method for bibliometric analysis is a combination of databases. The most popular research topics on PJI focused on alpha-defensin, antibiotic use, risk factors of intra-articular steroid injections, and the location of prosthetic hip and knee infection.
Highlights
Periprosthetic joint infection (PJI) is a serious and challenging complication after joint replacement
Database results Results from the search strategy demonstrated that the database with the most publications was Scopus (570), Fig. 1 Number of shared duplicate articles between the three databases
Fourteen institutions published more than one paper, with 50% originating from China (Table 2)
Summary
Periprosthetic joint infection (PJI) is a serious and challenging complication after joint replacement. Bibliometric analysis is a widely used tool that uses mathematical and statistical methods to assess research trends and growth Another commonly used tool is meta-analysis, a statistical method of collecting and analyzing results from multiple studies to find or prove the viewpoint or relationship between variables. These two methods have been applied extensively in orthopedic research [2,3,4,5,6]; there were few publications on the use of meta-analysis in bibliometric studies [7, 8]. The aim of the present study was to estimate global PJI research based on bibliometrics from meta-analysis studies
