We aimed to apply bibliometric tools to Australian and New Zealand orthopaedic publications produced between 2008 and 2018 to identify the most highly cited publications, author and institution collaboration networks and topic trends. Analysis of the literature can highlight areas of emerging interest and knowledge gaps, and direct future research.


A systematic search was conducted using Clarivate Analytics Web of Science. Citation analysis was carried out using Web of Science. Collaboration networks were constructed using chord diagrams. Trends in publication topics were analysed using simple linear regression to find the rate of change of publication volume on each topic.


A total of 3097 publications contributed to by 8855 individual authors met inclusion criteria. Across the study period, there was a large increase in the annual volume of publications on the topic of ACL (Anterior Cruciate Ligament) surgery. We also found that collaboration between Australian and New Zealand authors was very low with only 1% (n = 31) of publications including authors from both countries and 0.4% (n = 12) including orthopaedic surgeons or trainees from both.


Publications on ACL surgery have increased over the past decade, likely due to the presence of competing surgical approaches and the recently recognized risk of osteoarthritis following ACL reconstruction. The overall collaboration between Australian and New Zealand authors was very low which lends itself to opportunities for future research.
