Unicompartmental knee arthroplasty (UKA) is a treatment option for anteromedial osteoarthritis of the knee. The number of UKA has been increasing constantly worldwide in recent decades. The aim of this study was to determine the most frequently cited scientific articles addressing this subject and to establish a ranking of the 50 most influential papers.
The 50 most cited articles related to UKA were searched in Web of Science® (Clarivate Analytics, Penn., USA) by the use of defined search terms. All types of scientific papers with reference to this topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type, and level of evidence.
The 50 most cited articles had up to 453 citations. Most papers were published in the Journal of Bone and Joint Surgery (British volume). More than half of the articles were published in the 2000s and 2010s (n = 30). Ten countries contributed to the top 50 list, with most contributions from the UK (n = 17). Most articles could be attributed to the category of Clinical Science (n = 33), and most reported level IV studies.
Most of the frequently cited articles in UKA are clinical studies that have a low level of evidence. Few basic scientific studies could be identified, which suggests that most product development is done by commercial companies.
单髁膝关节置换术（UKA）是治疗膝关节前内侧骨关节炎的一种选择。近几十年来，全球范围内UKA的数量一直在持续增加。本研究的目的是确定关于该主题被引用最频繁的科学文章，并建立50篇最具影响力论文的排名。
通过使用特定的检索词，在科学网（Clarivate Analytics，宾夕法尼亚州，美国）中检索与UKA相关的被引用次数最多的50篇文章。所有涉及该主题的各类科学论文均根据引用的绝对次数进行排名，并分析以下特征：期刊名称、发表年份、引用次数、引用密度、地理来源、文章类型和证据水平。
被引用次数最多的50篇文章的引用次数高达453次。大多数论文发表在《骨与关节外科杂志》（英国版）上。超过一半的文章发表于21世纪头十年和2010年代（n = 30）。有10个国家的论文进入了前50名榜单，其中英国的贡献最大（n = 17）。大多数文章可归为临床科学类别（n = 33），且大多数报告的是IV级研究。
UKA中大多数被频繁引用的文章是证据水平较低的临床研究。几乎没有发现基础科学研究，这表明大多数产品开发是由商业公司完成的。
