A bibliometric analysis of research on developmental dysplasia of the hip (2000-2025): Trends, leading contributors, impact, and collaboration patterns.

PURPOSE: It was aimed to evaluate publication trends, scientific impact, and collaboration patterns in developmental dysplasia of the hip (DDH) research. METHODS: DDH-related publications indexed in the Web of Science database between January 1, 2000, and December 31, 2025, were analyzed. Publication output, citation metrics, author and institutional collaboration networks, leading journals, and major research themes were assessed. RESULTS: A total of 3462 articles were identified. Annual publication output increased substantially over the study period. The most cited article, by Steppacher et al., reported long-term outcomes of periacetabular osteotomy. Sankar WN (USA) was the most prolific author, while Clohisy JC (USA) had the highest citation impact and h-index. Shanghai Jiao Tong University (China) produced the greatest number of publications, whereas Western institutions achieved higher citation impact despite lower publication volumes. The USA led in publication output, while Switzerland demonstrated the highest citation impact. North American authors and institutions showed the strongest international collaboration rates, with the USA occupying the central position in the global collaboration network. The Journal of Pediatric Orthopaedics published the largest number of DDH-related articles. Research themes exhibited notable geographical variation. CONCLUSION: DDH research has grown rapidly over the past 25 years. North American and Western European researchers have played a leading role through strong international collaborations and publication in high-impact journals. Publication quality and global partnerships appear to be key determinants of scientific influence in the field. SIGNIFICANCE OF THE STUDY: This study provides novel bibliometric insights into the current landscape of DDH research for trainees, researchers, clinicians, and policymakers.
