Trends in Female Authorship in Orthopaedic Literature from 2002 to 2021: An Analysis of 168,451 Authors

Significant gender disparity exists in orthopaedic surgery. While women have increasingly entered the field, we are short of the critical mass needed to drive change, including in authorship. This study aimed to characterize trends in authorship in peer-reviewed orthopaedic journals in the context of gender. This is a cross-sectional bibliometric study of orthopaedic journals in the United States. Articles that were indexed in the orthopaedic category of the Clarivate Journal Citation Report (JCR) and the Science Citation Index Expanded (SCIE) were analyzed (n = 82). Journals not originating from the U.S. (n = 43) or not considered primarily orthopaedic journals (n = 13) were excluded. The 2020 impact factors (IFs) of the remaining 26 journals were recorded. The articles underwent automated data collection from PubMed for January 2002 to December 2021 using R software to collect the title, the journal, the publication year, the first and senior author names, and the country of origin. Gender was determined by Gender API (https://gender-api.com). Names with
