Authorship in the field of femoroacetabular impingement: an analysis of journal publications.

Purpose: This review provides a bibliometric analysis of the contributors to the field of FAI research.

Methods: A comprehensive search of three databases (MEDLINE, EMBASE, and PubMed) was performed to identify all clinical research articles on the topic of FAI (from inception to 2015). Cadaveric and animal studies were excluded. Study characteristics including authors, residing country of corresponding author, and journal were abstracted from the respective databases.

Results: In total, 1073 articles were included in this review. There were a total of 5471 different authors who contributed to the field of FAI research, 28.3 % of whom were only published in one article. The top 20 authors were associated with over half of all publications, and research studies were typically performed in their countries of residence. The greatest proportion of FAI-related articles was published in the Journal of Arthroscopy and Clinical Orthopaedics and Related Research.

Conclusions: The number of authors contributing to FAI research is increasing, suggesting not only increasing prevalence of FAI treatment among orthopaedic surgeons but also increasing interest among hip arthroscopists in furthering understanding regarding the diagnosis and management of the condition. The number of publications produced by the top 20 authors (and their affiliated countries: USA, Switzerland, Canada, and the UK) is expected to contribute to a majority of future publications. Current trends suggest that the quality of evidence will continue to improve in the near future, as large-scale, collaborative studies are currently underway.

Level Of Evidence: Retrospective study, Level IV.
