PurposeInternational English language publication activities in orthopaedic surgery comparing the years 2008/09 to 2018/19 were analyzed.Methods20 international journals listed on PubMed were examined. The impact factor (IF) for each journal was determined using the InCites Journal Citation Report.Results9,205 publications in 2008/09 and 15,549 in 2018/19 with 21,435 cumulative IF (CIF) in 2008/09 and 50,552 in 2018/19 were registered. Most publications consisted of narrative reviews (42.0%), followed by clinical studies (22.0%), experimental investigations (16.9%), randomized controlled trials (6.0%), and meta-analyses (5.6%). The highest increase in publications was observed for narrative reviews from 33.5% in 2008/09 to 41.1% in 2018/19. The USA had the highest number of publications (2,981 and 4,796), followed by UK (806 and 879) and Germany (606 and 922) in 2008/09 and 2018/19, resp. Per 1 Mio inhabitants, Switzerland (13.6 and 28.4), Sweden (10.9 and 18.1), the Netherlands (9.6 and 15.4), and Denmark (9.0 and 21.8) were the most productive countries in 2008/09 and 2018/19, resp.ConclusionsInternational publishing activity in orthopaedic surgery has increased substantially over the last 10 years. The quality of the published articles has not increased in the same way, as evidenced by the disproportionate rise in narrative reviews. Over the entire period, the US were the leader with respect to number of publications and CIF. In terms of population, however, smaller countries such as Switzerland and Sweden were much more active.© 2024. The Author(s).
