A Bibliometric Analysis of 4 Major Foot and Ankle Surgery Journals

Research publication is a central to the scientific process and comprehensive bibliometric analysis is a leading way to better understand trends within research. Currently, there are limited bibliometric analyses of literature pertaining to foot and ankle surgery. This study aims to quantify the volume of research and investigate what may affect publication and citation. Journals associated with the 3 major orthopedic foot and ankle societies (Foot & Ankle International[FAI], Foot and Ankle Surgery, and The Foot) and one podiatric college (Journal of Foot and Ankle Surgery®) were evaluated from January 2009 to December 2018 using Scopus (Elsevier, Amsterdam, the Netherlands). Descriptive statistics were used to summarize article characteristics and regression modeling was used to determine factors associated with a country's current and future productivity and an article's citation rate. A total of 4994 articles were published over the 10-year period, with the largest contributor of publications being the United States of America (USA), who produced 2096 (41.8%) publications. Regression analysis found no association between a country's productivity and gross domestic product or population. There was no significant relationship between a country's baseline publication rate and future publication rate. The variables significantly associated with an increased citation count were; the number of years since publication, the number of authors, publication in FAI and if the article was a review. To our knowledge this is the largest bibliometric analysis of foot and ankle publications. The majority of research is being produced by the USA, but there are numerous complex factors associated with citation and publication rates. Further research is required to fully assess these factors and characterize the state of foot and ankle surgery research.
