Among them, the USA contributed to the most publications , In order to predict the future, the time curve of the all-year publication numbers was created by using the logistic regression model, and the model fitting curves of the growth trend was shown in Fig. Furthermore, with the help of this time curve, it is estimated that the number of the publications in this domain would grow by nearly 3. The USA had the highest number of total citations 42, among all the included publications, while the UK ranked the second , then followed by Canada , China , and Germany Fig.

Publications from Denmark had the most average number of citations As shown in Fig. Knee Surgery, Sports, Traumatology, Arthroscopy ranked the second, with publications. The top 20 journals with the most publications were presented in Fig. The top 20 research orientations relevant to TKA were shown in Fig. The most prevalent areas of research were orthopedics papers , surgery papers , sport science papers , engineering papers , and general internal medicine papers , respectively. The top 20 authors with the greatest number of related publications were shown in Fig. Hospital special surgery had the greatest number of publications with papers, followed by the Mayo Clinic papers and then the University of California system papers. Figure 3 d presented the top 20 institutions with the most publications.

As a well-established method of citation analysis, bibliographic coupling helps create a similarity relationship between documents on the basis of the number of references they share. When two works refer to a common third one in their bibliographies, bibliographic coupling occurs as an indication of sharing a related subject matter for these two works [ 22 ]. The VOS viewer was used to analyze the journal names of all publications. As illustrated in Fig. Bibliographic coupling analysis of global research on TKA. Papers originating from institutions were analyzed via VOS viewer, and the minimum number of publications from each institution was over five in the bibliometric map Fig. There were 57 countries and regions included the minimum number of publications from each country or region was over five and all the publications were analyzed by VOS viewer Fig.

Coauthorship analysis illustrates the relationship among items based on the number of coauthored documents, which was a powerful tool to assess collaboration trends and to identify leading scientists, countries, and organizations [ 23 ]. As presented in Fig. Coauthorship and cocitation analysis of global research on TKA. A total of 56 countries and regions with a minimum limitation of more than 5 publications were identified and analyzed by using VOS viewer Fig.

Cocitation analysis establishes the relationship of items on the basis of how many times they are cited together and is demonstrated as a way to help identify key literature for cross-disciplinary ideas [ 24 ]. A total of publications were included the minimum number of citations for one reference was over 20 times and analyzed via VOS viewer Fig. The top five publications with largest TLS were presented as follows: Insall et al. The journal was included if the minimum number of citations from one source was over 20 times. In total, there were journals which met the aforementioned criteria Fig. Co-occurrence analysis illustrates the relationship of items based on the number of publications where they occur together [ 30 ].

Not only the popular areas and research directions could be identified through co-occurrence analysis, but also it turns out to be an important indicator to monitor developments in scientific areas and other disciplines. The keywords, which were used over five times among included publications, were identified and analyzed via VOS viewer. The most prominent topics about TKA research were shown as follows. Co-occurrence analysis on TKA research.

A total of included keywords are divided into 5 clusters: alignment study color green , revision TKA study color blue , complication study color red , rehabilitation study color yellow , and perioperative management study color purple. The color blue indicates the keywords appear earlier, whereas the color red reflects the later occurrence. In Fig. The color blue indicated the keywords appeared earlier, whereas the color red stood for the later occurrence. However, recent trends indicated that the other four clusters were also undergoing different degrees of changes on the research hotspot, which meant a diversified developing trend.

Bibliometric and visualized analysis is considered as valid tools for describing the current status and predicting the future development trends about the research of interest. Therefore, we aim to evaluate TKA research through bibliometric and visualized analysis and further illustrate its future global trends from the aspects of publications, contributing countries, institutions, and the research orientations. In the past decades, great development happened in the evolving field of TKA research.

As shown in this study, the number of publications has steadily increased year by year. In addition, the RRIs of publications had also risen dramatically in the meantime. A total of 86 country and regions have published papers in this domain, which indicated a potential increase of studies which focus on TKA research and offer in-depth knowledge in the next few years.

The total number of citations and the H-index reflect the quality of the publications and academic impact of one country [ 31 ]. According to our study, the USA outranked the other countries in terms of the total number of publications and citations, as well as H-index, making the largest contribution to global TKA research. The UK and Canada also contributed a lot with a considerable total citation frequency and H-index, especially for Canada, which ranked second in the average citation frequency. Nevertheless, some countries such as Denmark, Canada, and Belgium have also played an important role when considering their high average citation frequencies. It was worth noting that developing countries also made crucial contributions.

For instance, China ranked among top five with regard to the total number of publications and citations, along with H-index. Due to the high incidence of knee arthritis, large population base and subsequent great numbers of TKAs, developing countries therefore made enormous investments in the field of TKA research, which might partially explain this result. According to this trend, the listed journals in Fig. Almost all of the top 20 institutions were from the top five countries with the largest publication numbers, and more than half of them were located in the USA, once again reflecting the great academic impact of the USA in this area.

This indicated the significant role of these first-class institutions in improving the academic level of a country. The top 20 authors listed in Fig. Therefore, in order to grasp the latest advancements in this filed, more attention should be paid on their work with a relatively high priority. In this study, bibliographic coupling analysis was used to illustrate the similarity relationship between the identified publications from the aspects of journal, institution, and country, respectively.

Bibliographic coupling occurs when two studies share with the common references in their bibliographies, so that it can provide a deep, direct insight on the links among these relevant literature and further interpret how these links are built and used by the authors. According to our data, The Journal of Arthroplasty was the most closely related journal, and the Hospital for Special Surgery published the most relevant papers. As for the countries, the USA outshined the rest of the countries which maintained its leading position in the domain of TKA research. Coauthorship analysis was utilized to evaluate the collaboration between different authors, countries, and institutions.

Cocitation analysis was conducted to illustrate the influence of studies, by counting how many times they were cited together. In our study, Clinical Orthopaedics and Related Research was the journal with the highest citation frequency, which could be considered as the landmark studies about the TKA research. Co-occurrence analysis was based on the number of publications with the common occurrence, so as to evaluate the relationship among identified items. Furthermore, it was considered as an efficient way to predict the future trends and hotspots in the research field of interest.

In our study, we presented a network map of co-occurrence relationship by analyzing the keywords of all the included studies. With the help of this network map, we had chances to further clarify the developing trends in the future. The overlay visualization map, with items which were noted with different color according to the average time when the keywords occurred [ 32 ], was kind of similar to the co-occurrence map. However, it could more directly monitor the progress of the research and predict the popular topics in the future. In this overlay visualization map Fig. Nevertheless, nodes of various colors from blue to red could all be found with considerable densities in the five clusters, which meant a trend of balanced development existed in these five research directions respectively during the past decade.

Furthermore, each direction itself was also undergoing the changes of research hotspot, which indicated a diversified developing trend. In light of our findings in this study, the number of publications related to TKA research has been rapidly growing since Therefore, TKA continues to thrive and play an important part in managing severe knee arthritis, which is served as the effective surgical therapy for end-term arthritis.

This blossoming result will in turn encourage more and more researchers to devote to future study. Through the bibliometric and visualized analysis, investigators could have a vivid overall impression of this field, including the leading countries, authors, and institutions, along with the partnership and academic impact of them. Furthermore, the co-occurrence analysis could depict the developing trends and research hotspots in this area, which may further provide the researchers with inspirations of topic selection and help the funding agencies make profit investment plans.

To the best of our knowledge, this is the first study which conducted bibliometric analysis on TKA research. To better comprehensively capture the current status and future trends of researches on TKA, bibliometric and visualized analysis were used to identify the hotspots and collaborative relationship among different countries, authors, and institutions. However, this study inevitably has some limitations.

Firstly, although the included publications were adequate enough to reflect the current status, we only retrieved data from WoS database. J Arthroplast.

In order for the Medical Advisory Secretariat to measure the effectiveness of TKR and to compare the effectiveness of TKR across studies, effect sizes were calculated in studies that reported the standard deviations of the preoperative and postoperative measurement scores. Percent change was also calculated. Summary of findings: Overall, patients who undergo TKR surgery for osteoarthritis have substantial improvements in terms of reduction of pain and improvement of function.

A comparison of the mean effect score and the percent change in 19 studies that reported preoperative and postoperative outcome scores for patients who had TKR showed that the procedure is effective. The 19 studies included patients of various ages and used a variety of prostheses and techniques to implant the device. TKR was effective in all of the studies. As for the factors that predict TKR outcomes, a variety of factors have been evaluated, including obesity, age, gender, prosthesis design, and surgical techniques; however, none of these have been shown to predict outcomes pain or function consistently across studies. In terms of the timing of TKR surgery, 2 studies found that the severity of osteoarthritis does not predict outcome, but 1 study was found that higher functioning patients had significantly less pain and better function up to 2 years after surgery compared with lower functioning patients.

It is important to note that the patients in the low and high function groups were evenly matched on comorbid conditions. Unicompartmental knee replacement surgery seems to be as effective as TKR surgery for people who meet the indications for it. This is a subset of people who have osteoarthritis of the knee, because for unicompartmental knee replacement to be indicated, only 1 usually the medial compartment of the knee can be affected.
