Abstract
ObjectiveAs an alternative of knee-protection surgery, unicompartmental knee arthroplasty has been widely used for the treatment of knee osteoarthritis and has achieved good clinical results. However, reports on its data and trend are scanty. This article reviewed current status and trend in the research of UKA, and compared different regions, organizations and authors in terms of their contributions to the field.MethodsThe literature on UKA ranging from 2009 to 2019 was searched in the “Web of Science” database, and the search results were visually presented by using Excel and VOS-viewer software packages, and the status quo and development trends of relevant studies were analyzed.ResultsA total of 1264 articles on UKA were identified, of which 330 were the larger studies conducted in the United States. The institution that published most papers was Oxford University, with a total of 109 papers published. MURRAY DW was the largest contributor in this field. The National Institutes of Health was the largest funding agencies of the UKA. Studies could be divided into six clusters in terms of prosthesis design, follow-up investigation, OA etiology, hip-knee association, joint replacement registration, and computer navigation. “Computer-aided navigation” and “gait analysis” promise to be future hot spots in the field of UKA research.ConclusionGlobal trend analysis suggests that UKA research is gradually deepening and the number of papers has been on the rise. The USA was the largest contributor to this field. More research effort should be directed to “Computer-aided navigation”and “gait analysis”, which might be the popular topics in the UKA field in not very distant future.
Highlights
Knee osteoarthritis (KOA) is a degenerative joint disease that is prevalent in middle-aged and elderly people
The total cited frequency (4508) and High Citations Index (H-index) (34) of papers published in the United States were the highest
The study compared the clinical efficacy in 10,133 patients undergoing Total Knee Arthroplasty (TKA) or Unicompartmental knee arthroplasty (UKA), and the results showed that the 8-year revision rate was higher in UKA group (2.12%) than in TKA group (1.38%)
Summary
Knee osteoarthritis (KOA) is a degenerative joint disease that is prevalent in middle-aged and elderly people. With the stepwise treatment of KOA, the standardized preaching and promotion of Bibliometrics is a method that uses literature data as a research object to conduct qualitative and quantitative research on published literature through keywords, titles, authors, institutions, etc., to quickly assess the research status of a certain field and predict its development trend [6]. Bibliometric analysis is gradually being (2020) 2:20 used to develop clinical practice guidelines and analyze the trends in the research of related diseases [7]. UKA has been extensively employed for the treatment of KOA [8]. There is a paucity in the statistics and trend research of UKA in literature
