Patellar instability is a common multifactorial disease in orthopedics, which seriously affects the quality of life. Because of the unified pathogeny, diagnosis and treatment, patellar instability has gradually attracted the interest of more scholars these years, resulting in an explosive growth in the research output. This study aims to summarize the knowledge structure and development trend in the field from the perspective of bibliometrics.
The data of articles and reviews on patellar instability was extracted from the Web of Science database. The Microsoft Excel, R-bibliometrix, CiteSpace, VOSviewer, Pajek software are comprehensively used to scientifically analyze the data quantitatively and qualitatively.
Totally, 2,155 papers were identified, mainly from North America, Western Europe and East Asia. Until December 31, 2021, the United States has contributed the most articles (1,828) and the highest total citations (17,931). Hospital for Special Surgery and professor Andrew A Amis are the most prolific institutions and the most influential authors respectively. Through the analysis of citations and keywords based on a large number of literatures, "medial patellofemoral ligament construction", "tibial tubercle-trochlear groove (TT-TG) distance", "epidemiological prevalence", "multifactor analysis of etiology, clinical outcome and radiographic landmarks " were identified to be the most promising research directions.
This is the first bibliometric study to comprehensively summarize the research trend and development of patellar instability. The result of our research provides the updated perspective for scholars to understand the key information in this field, and promote future research to a great extent.
髌骨不稳定是骨科常见的多因素疾病，严重影响生活质量。近年来，由于其发病机制、诊断和治疗的统一性，髌骨不稳定逐渐引起了更多学者的关注，研究成果呈爆发式增长。本研究旨在从文献计量学角度总结该领域的知识结构和发展趋势。
从科学引文索引（Web of Science）数据库中提取有关髌骨不稳定的文章和综述数据。综合运用Microsoft Excel、R-bibliometrix、CiteSpace、VOSviewer、Pajek软件对数据进行科学的定量和定性分析。
共检索到2155篇论文，主要来自北美、西欧和东亚。截至2021年12月31日，美国发表的文章数量最多（1828篇），总被引次数最高（17931次）。特种外科医院和安德鲁·A·阿米斯教授分别是发文量最多的机构和最具影响力的作者。通过对大量文献的引文和关键词分析，确定“内侧髌股韧带重建”“胫骨结节-滑车沟（TT-TG）距离”“流行病学患病率”“病因、临床结局和影像学标志的多因素分析”是最有前景的研究方向。
这是首次全面总结髌骨不稳定研究趋势和发展的文献计量学研究。我们的研究结果为学者们了解该领域的关键信息提供了新的视角，并在很大程度上促进了未来的研究。
