Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. However, to the best of our knowledge, no studies have documented the main characteristics of arthroplasty publications from different countries. This study aimed to evaluate the worldwide research productivity and status of Turkey in the field of arthroplasty using bibliometric methods and to provide an insight into the arthroplasty research for surgeons and researchers.
The Web of Science database was searched to identify arthroplasty articles published between 2006 and 2016. The contributions of countries were evaluated based on publication count, citation average, h-index and publication rate in the top 10 ranked journals. Each countries publication output was adjusted according to population size.
A total of 26.167 articles were identified. World arthroplasty publications were increased significantly over time (p < .005). The United States was the most productive country with 9007 articles (34,4% of total) followed by England with 2939 articles (11,4 of total) and Germany with 1881 articles (7,1% of total). According to average citations per item, Scotland was in the first place followed by Denmark and Sweden, whereas in the first place according to publication output adjusted by population size was Switzerland followed by Denmark and Scotland. The United States was also in the first place according to h-index and publication rate in the top 10 ranked journals. Founding average was 28,8% (7539 of 26164) for the arthroplasty articles that were analyzed in the study.
There is a rapid increase in the number of articles in arthroplasty research from 2006 to 2016. The United States was the most productive country as measured by total publications in the arthroplasty field. However, some small European countries with high in-come have higher quality of articles and better productivity when adjusted for population. Gross domestic product (GDP) per capita and research foundation had positive affect on arthroplasty publications, both qualitatively and quantitatively.
文献计量学在全球许多研究领域越来越多地用于评估科研产出的数量和质量。然而，据我们所知，尚无研究记录不同国家关节成形术出版物的主要特征。本研究旨在运用文献计量学方法评估土耳其在关节成形术领域的全球研究生产力和地位，并为外科医生和研究人员提供关节成形术研究的见解。
检索科学网数据库，以识别2006年至2016年间发表的关节成形术文章。根据发表数量、平均被引次数、h指数以及在排名前十的期刊上的发表率评估各国的贡献。根据人口规模对每个国家的发表产出进行调整。
共识别出26167篇文章。全球关节成形术出版物数量随时间显著增加（p <.005）。美国是产出最多的国家，有9007篇文章（占总数的34.4%），其次是英国，有2939篇文章（占总数的11.4%），德国有1881篇文章（占总数的7.1%）。按每篇文章的平均被引次数计算，苏格兰位居第一，其次是丹麦和瑞典，而按人口规模调整后的发表产出计算，瑞士位居第一，其次是丹麦和苏格兰。美国在h指数以及在排名前十的期刊上的发表率方面也位居第一。本研究分析的关节成形术文章的基金平均比例为28.8%（26164篇中的7539篇）。
2006年至2016年关节成形术研究文章数量迅速增加。按关节成形术领域的总发表量衡量，美国是产出最多的国家。然而，一些高收入的欧洲小国在按人口调整后文章质量更高且生产力更好。人均国内生产总值（GDP）和研究基金在定性和定量方面都对关节成形术出版物有积极影响。
