We studied the publication trend in the field of orthopaedics and sports medicine over the last 25 years (1996 - 2021), by various countries, and regions of the world. There was an increasing trend in publications, across the globe. Some of the Asian countries like China and India have shown a substantial growth in their research output. Europe continent has contributed the most publications in the last 25 years, whereas the United States as a country has been on the top of the list of contributors. Most research-publications came from high-income countries and disproportionately less from low- and middle-income countries.
