Top 50 most cited articles in revision total hip arthroplasty research

A bibliometric analysis of the top 50 cited studies related to acromioclavicular joint instability

Background

Acromioclavicular joint (ACJ) injury is a common orthopaedic condition accounting for over 40 % of all shoulder injuries. The purpose of this study is to assess the research trends and characteristics of the top 50 cited articles on ACJ instability.

Methods

A systematic search was conducted in Web of Science to identify articles primarily related to ACJ injury or instability. Characteristics including citation number, country of origin, journal and institution of publication, impact factor, authorship, level of evidence, patient demographics, and study type were analyzed and recorded.

Results

Research output on ACJ instability has been steadily increasing, with the top 50 cited studies predominantly presenting Level IV evidence. These studies primarily focused on treatment outcomes which included predominantly male patients and exhibited a large variation in citation counts. The American Journal of Sports Medicine was the most productive journal, and the USA was the most productive nation.

Conclusion

There is an increasing number of publications in the ACJ instability literature, primarily concentrated in a few institutions and journals, and focusing mainly on treatment outcomes. A significant portion of these publications are of low scientific quality, and there is a notable lack of research on outcomes for females.

The most influential studies concerning revision shoulder arthroplasty research

Background

Bibliometric analysis is a unique tool that can be used to study the characteristics and trends of a given topic. This study aimed to report on the most influential studies concerning revision shoulder arthroplasty research.

Methods

On July 4th, 2022, the Institute of Scientific Information (ISI) Web of Knowledge Database was used to identify articles concerning revision shoulder arthroplasty research. The top 50 most cited articles were selected and analyzed.

Results

The mean number of citations was 142 (median: 97; range 599-70). Most articles were published in the 2010s (56%), followed by the 2000s (38%), and 1990s (6%). The most common level of evidence (LOE) was LOE II (42%) followed by LOE IV (38%), LOE I and III each had 10%. The greatest number of papers were published in the Journal of Shoulder and Elbow Surgery (46%), followed by the Journal of Bone and Joint Surgery- American Version (14%).

Conclusion

This review can serve as a useful tool to study the most influential articles concerning revision shoulder arthroplasty research. Most of the articles were classified as clinical outcomes (62%), followed by natural history/epidemiology (12%), and surgical technique (10%). Our findings suggest that high-quality studies (LOE I) are lacking and other areas of research besides clinical outcomes are not as well studied.
