Global publication trends and research hotspots of revision hip and knee arthroplasty: A 21-year bibliometric approach.

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.Publications related to RHKA from 2000 to 2020 were searched in the Web of Science database. WPS Office, CiteSpace, VOS Viewer, and Bibliometrix were used to analyze the results.Bibliometric analysis revealed 3290 records. Fifty-nine countries published manuscripts on RHKA. The United States (US) 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.The present study observed an increasing trend of research papers in RHKA. Institutions and scholars from the USA were found to dominate the field. Periprosthetic joint infection was likely a potential development trend and hot spot of RHKA.
