Purpose To identify the quantity and types of spin present in systematic reviews and meta‐analyses of ulnar collateral ligament reconstruction (UCLR) outcomes and to characterize the studies with spin to determine if any patterns exist. Methods This study was conducted per Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. In August 2022, PubMed, Scopus, and SportDiscus databases were searched using the terms “ulnar collateral ligament reconstruction” AND “systematic review” OR “meta‐analysis.” Each abstract was assessed for the presence of the 15 most common types of spin derived from a previously established methodology. General data that were extracted included study title, authors, publication year, journal, level of evidence, study design, funding source, reported adherence to PRISMA guidelines, preregistration of the study protocol, and methodologic quality per A Measurement Tool to Assess Systematic Reviews Version 2 (AMSTAR 2). Results In total, 122 studies were identified during the preliminary search, of which 19 met the inclusion criteria. Each study had at least 1 form of spin. The most common type of spin identified was type 5 (“The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies”) (7/19, 36.8%). AMSTAR type 9 (“Did the review authors use a satisfactory technique for assessing the RoB [risk of bias] in individual studies that were included in the review?”) was associated with both a lower Clarivate Impact Factor ( P = .001) and a lower Scopus CiteScore ( P = .015). Studies receiving external funding were associated with the failure to satisfy AMSTAR type 3 (“Did the review authors explain their selection of the study designs for inclusion in the review?”) ( P = .047). Conclusions Spin is highly prevalent in the abstracts of systematic reviews and meta‐analyses that investigate the outcomes of UCLR. Clinical Relevance Spin has been identified in peer‐reviewed articles published on various topics, including many in orthopaedics. Systematic reviews and meta‐analyses contain the most comprehensive evidence regarding a clinical question, so it is important to identify spin that may be included in these reports. Greater efforts are needed to ensure that the abstracts of papers accurately represent the results in the full text.
