Perspectives of Femoroacetabular Impingement Syndrome: A Bibliometric Analysis.

Femoroacetabular impingement syndrome (FAIS) is a risk factor for future hip osteoarthritis and is prevalent in both athletic and non-athletic populations. This bibliometric review aimed to understand the history of FAIS and provide detailed information for future FAIS research. The Clarivate Analytics Web of Science Core Collection was used to search and obtain all studies between 2020 and 2025 using bibliometrix (ver. 3.0.4) and R package software. Between 2020 and 2025, 1,486 articles were published on FAIS. There was an overall 41.3% downward trend in published research during this period. Furthermore, recent key terms include "physical impairments" and "muscle strength". Institutions and surgical authors across North America, Europe, and Australia published the highest volume of research papers. Across keywords, femoroacetabular impingement and osteoarthritis had the strongest relationship. FAIS research continues to be led by surgical authors within surgical journals. While surgical key terms have been historically prevalent within the existing literature, research aligning with more conservative management has started to emerge. Despite an increase in physiotherapy researchers, inter-disciplinary collaboration remains limited and concentrated in western countries.
