Background:
Acromioclavicular joint (ACJ) reconstruction has been widely studied; however, the methodological quality of its most cited research remains uncertain. Citation-based analyses have emphasized the influence of frequently cited studies.
Purpose:
To (1) identify the 50 most cited original studies on ACJ reconstruction and assess their methodological quality using established scoring systems, and (2) explore correlations between study quality, citation count, and citation density.
Study Design:
Cross-sectional study.
Methods:
A Web of Science search (1946-August 2024) identified publications on ACJ reconstruction. The 50 most cited articles were analyzed for bibliographic details, citation metrics, and level of evidence (LOE). Clinical studies were assessed using the Modified Coleman Methodology Score (MCMS), Methodological Index for Non-Randomized Studies (MINORS), and Methodological Quality for Clinical Studies of Radiologic Examinations (MQCSRE). Cadaveric studies were evaluated using the Biomechanics Objective Basic Science Quality Assessment Tool (BOBQAT).
Results:
The 50 most cited articles garnered 5918 citations, with a mean of 118 ± 62 citations per article. Most articles were published in the American Journal of Sports Medicine, accounting for 56% of the total (n = 28). Clinical studies accounted for 66% (n = 33) of the articles, while cadaveric studies comprised 34% (n = 17). The United States was the leading contributor (44%; n = 22), followed by Germany (22%; n = 11). Significant correlations were observed between citation counts and the MINORS (r = 0.37; P < .05) scores and LOE (r = -0.37; P < .05). No significant correlations were found between citation counts and the MCMS (r = 0.24; P > .05), MQCSRE (r = 0.20; P > .05) or BOBQAT (r = -0.22; P > .05). Analysis of citation density indicated that recent decades (2011-2020) showed increased values, showing trends in research activity.
Conclusion:
Study quality was partially correlated with citation counts among highly cited clinical studies on ACJ reconstruction. The overall methodological quality was moderate, highlighting the need for higher-level evidence. This article serves as a reference for key literature.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
