Background:
Scientific publication and original articles remain the primary method of sharing scientific findings and advancing the knowledge base of that subject. Despite the value of these publications, little research has surveyed what topics are being published. This study aims to identify and characterize the most common topics in current foot and ankle literature.
Methods:
We reviewed all 1514 published articles in a 5.5-year period (January 2014–June 2019) in 2 foot and ankle–specific journals: Foot & Ankle International (FAI) and Foot and Ankle Surgery (FAS). The articles were sorted into different topic domains to identify the 3 most common categories of publication. The top 3 domains were further characterized by level of evidence (LOE) as well as citations.
Results:
The 3 most published topics in foot and ankle literature were hallux valgus (8.3%), total ankle arthroplasty (TAA) (8.3%), and ankle fracture (6.6%). These 3 subjects accounted for 351 articles (23.2%). Other common topics were patient-reported outcomes (5.0%), osteochondritis dissecans (3.9%), syndesmotic injury (3.8%), ankle instability (3.7%), hallux rigidus (3.0%), and anatomy (2.8%). The average LOE for articles on hallux valgus, TAA, and ankle fracture was 3.27 from FAI, and the average number of annual citations for a given article in both journals was 3.05. Based on our study, there is no correlation between LOE and number of overall citations, but there is a significant, negative linear correlation in ankle fracture data. We also found that articles on TAA had the highest impact factor and that articles from FAI were cited more often than articles from FAS.
Conclusion:
The 3 most published topics in foot and ankle literature comprise only 23.2% of all articles. This finding is indicative of the wide variety of cases performed by orthopaedic foot and ankle surgeons. High-quality data are still needed in all topics.
Level of Evidence:
Level III, retrospective cohort study.
