The usefulness of orthopedic shoulder surgery randomized controlled trials: are they meeting the key criteria?

Background: Shoulder surgery is a significant subset of orthopedic interventions, and randomized controlled trials (RCTs) are critical for advancing surgical techniques and informing clinical guidelines. However, poorly designed or inadequately reported RCTs make applying findings to clinical practice more difficult. This study applies a usefulness assessment tool developed by van 't Hooft et al to evaluate the utility of shoulder surgery RCTs published in the past 5 years, aiming to identify trends and gaps to improve trial design and reporting. Methods: This study evaluated RCTs on orthopedic shoulder surgery published between January 1, 2019, and October 28, 2024. Using Medline and Embase, articles were screened for inclusion based on predefined criteria. Data extraction focused on general trial characteristics and fulfillment of 13 items within the usefulness criteria. Each criterion was scored from 0 to 2, with a maximum total score of 26. Statistical analysis included descriptive statistics for trial characteristics, linear regression models for scores and time, and a correlation analysis between core usefulness and transparency scores. Results: The mean usefulness score was 13.0 of 26, with scores ranging from 6 to 23. Core usefulness scores showed a slight decline over time, while transparency scores exhibited an upward trend, leading to a modest overall increase in combined scores. Transparency items, such as conflict of interest and funding disclosures, were well-reported, while public availability of raw data and trial protocols scored poorly. Core usefulness items like problem base and feasibility were widely achieved, but pragmatism and value for money were frequently unmet. A moderate positive correlation (r = 0.29, Discussion and Conclusion: While transparency improvements have driven slight overall progress in trial quality, substantial gaps remain in key criteria like raw data availability and value for money. The findings highlight the need for journals and researchers to adopt comprehensive strategies to enhance the clinical impact of RCTs. This study underscores the value of structured assessment tools in identifying opportunities to optimize trial design and reporting, ultimately improving evidence-based care in orthopedic shoulder surgery. This study highlights persistent gaps in transparency among shoulder surgery RCTs and suggests that improved reporting, particularly regarding protocol and data availability, may enhance the overall usefulness and reliability of trial findings.
