Summary
Femoroacetabular impingement syndrome (FAIS) research shows a downward trend, with key terms shifting towards physical impairments and muscle strength. Collaboration remains limited, despite emerging conservative management studies.
Area of Science:
- Orthopedics
- Sports Medicine
- Rehabilitation Science
Background:
- Femoroacetabular impingement syndrome (FAIS) is a significant risk factor for developing hip osteoarthritis.
- FAIS affects both athletic and non-athletic individuals, highlighting its broad prevalence.
- Understanding the trajectory of FAIS research is crucial for future scientific inquiry.
Purpose of the Study:
- To conduct a bibliometric analysis of research on femoroacetabular impingement syndrome (FAIS).
- To map the historical development and current trends in FAIS research.
- To identify key themes, institutions, and collaborations in the field.
Main Methods:
- Bibliometric analysis of 1,486 articles published between 2020 and 2025.
- Data sourced from the Clarivate Analytics Web of Science Core Collection.
- Utilized bibliometrix (ver. 3.0.4) and R package software for analysis.
Main Results:
- A 41.3% downward trend in FAIS publications was observed from 2020-2025.
- Emerging keywords include "physical impairments" and "muscle strength".
- Strongest keyword association found between femoroacetabular impingement and osteoarthritis; research led by North American, European, and Australian institutions.
Conclusions:
- FAIS research is increasingly exploring conservative management alongside traditional surgical focus.
- Limited inter-disciplinary collaboration exists, primarily concentrated in Western countries.
- Physiotherapy researchers are increasing, but collaboration with other fields remains a challenge.
