A Bibliometric Review of the Top 100 Most Cited Articles in Hip Preservation, Not Counting Self-Citations

Abstract

Purpose

To summarize the characteristics of the top 100 most-cited publications related to hip preservation, not counting self-citation.

Methods

Databases accessible through ISI Web of Science were queried for articles related to hip preservation between 1965 and June 2022. Analysis included citation number, visual network mapping, publication year, geographic distribution, authorship, impact factor, citation density, and institution. Data analysis was performed excluding self-citations.

Results

The top 100 most cited articles in hip preservation had citations ranging between 151 and 2,001, with publication years between 1965 and 2018. An increase in citation density over time was observed. Fifty-seven percent of articles were from the United States, 23% from Switzerland, and 8% from Canada; 57% of the articles were published in the 2000s, and a majority were Level IV Evidence (n = 62). Clinical Orthopaedics and Related Research led in number of publications (n = 32) and mean citations (n = 353) followed by Arthroscopy—The Journal of Arthroscopic and Related Surgery (n =23) and American Journal of Sports Medicine (n = 11). “Femoroacetabular impingement” (occurrences = 19) and “arthroscopy” (15) have been focal keywords since the turn of the 21st century, whereas in the 20th century, “acetabulum” (occurrences = 2) was the predominant keyword.

Conclusions

The 100 most-cited articles in hip preservation, not counting self-citation, were published between 1965 and 2018. Citation density increased over time. The majority of articles were published in the United States and in Clinical Orthopaedics and Related Research. The focus in hip preservation has expanded from acetabulum pathology to extensive work across topics including femoroacetabular impingement, capsular biomechanics, and arthroscopy innovation.

Level of Evidence

Level IV, descriptive epidemiology study using large database.
