Objective To determine the quantity and quality of articles in the field of knee arthroplasty worldwide and elucidate the characteristics of global scientific production. Methods Web of Science was used to identify articles in the field of knee arthroplasty from 2011 to 2015. The total number of papers, number of papers per capita, total number of citations, and mean number of citations were collected. Results In total, 11,590 papers were identified. The number of publications significantly increased from 2011 to 2015. Most originated from North America, East Asia, and West Europe. Most (88.51%) were from high-income countries, 11.48% were from middle-income countries, and only 0.01% were from lower-income countries. The United States had the most articles and total citations. Sweden had the highest mean citations, followed by Denmark and Canada. However, when adjusted by population size, Denmark had the most articles per million population, followed by Switzerland and the Netherlands. Conclusions The number of knee arthroplasty publications has rapidly increased in recent years. The United States is the most prolific, but some European countries are more productive relative to their population.
目的 确定全球膝关节置换领域文章的数量和质量，并阐明全球科研产出的特征。方法 使用科学网检索2011年至2015年膝关节置换领域的文章。收集论文总数、人均论文数、总被引次数和平均被引次数。结果 共识别出11590篇论文。2011年至2015年期间论文数量显著增加。大多数论文来自北美、东亚和西欧。大多数（88.51%）来自高收入国家，11.48%来自中等收入国家，仅有0.01%来自低收入国家。美国的文章数量和总被引次数最多。瑞典的平均被引次数最高，其次是丹麦和加拿大。然而，按人口规模调整后，丹麦每百万人口的文章数量最多，其次是瑞士和荷兰。结论 近年来膝关节置换领域的出版物数量迅速增加。美国的产出最多，但一些欧洲国家相对于其人口而言产出更高。
