Summary
Spin is common in abstracts for rotator cuff repair reviews, especially those with poor methodology. Critical appraisal of these reviews is essential for accurate clinical decision-making.
Area of Science:
- Orthopedic Surgery
- Evidence-Based Medicine
- Research Methodology
Background:
- Rotator cuff tears cause significant shoulder pain and dysfunction.
- Patch augmentation aims to reinforce surgical repair and reduce retears.
- Concerns exist regarding heterogeneity and spin in existing systematic reviews on this topic.
Purpose of the Study:
- To assess the methodological quality and abstract spin in systematic reviews and meta-analyses of patch-augmented rotator cuff repair.
Main Methods:
- Systematic review adhering to Cochrane Handbook and PRISMA guidelines.
- Searched PubMed, Scopus, and Web of Science for relevant reviews up to October 30, 2025.
- Assessed methodological quality using AMSTAR-2 and spin using Yavchitz et al.'s criteria.
Main Results:
- Sixteen reviews were included; 81.3% of abstracts exhibited spin.
- No significant association found between spin and funding status, quality, or impact factor.
- Each AMSTAR-2 flaw correlated with a 61% increase in spin types (IRR 1.61, p=0.02).
Conclusions:
- Spin is prevalent in abstracts of rotator cuff repair augmentation reviews.
- Poor methodological quality, not funding or impact factor, is linked to increased spin.
- Critical appraisal of systematic reviews is crucial to mitigate biased interpretation and guide clinical decisions.
