This study aims to assess the methodological rigor of available reviews using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2) and to explore associations with publication characteristics, including citations, journal impact factor, year of publication, and PRISMA adherence. A systematic literature search of PubMed, Scopus, and the Cochrane Library was performed. Two authors independently screened studies and extracted data. Methodological quality was assessed with AMSTAR-2. Correlations between AMSTAR scores and publication features were evaluated using Spearman's rank correlation, and differences by PRISMA adherence were tested with the Mann\u2013Whitney U test. Interrater reliability was assessed with Cohen's kappa. Thirteen systematic reviews were included. Most focused on safety and complication rates of fat grafting vs implants. According to AMSTAR-2, 11 reviews were rated \u201ccritically low\u201d and 2 \u201clow.\u201d Spearman correlations indicated a moderate positive association between AMSTAR score and year of publication (r = 0.46) and a weak-to-moderate association with the number of included studies (r = 0.39). No significant associations were observed with journal impact factor or citation count. PRISMA adherence was reported in 69% of reviews but did not significantly affect AMSTAR scores (P = .536). Although systematic reviews on gluteal augmentation are increasing, their methodological quality remains largely low. Future reviews should implement prospectively registered protocols, comprehensive search strategies, and rigorous risk-of-bias assessment to provide reliable guidance for clinical practice.<\/jats:p>\n                  <jats:p>Level of Evidence: 3 (Therapeutic) For image description, please refer to the figure legend and surrounding text.<\/jats:p>","DOI":"10.1093\/asjof\/ojag162","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T07:21:42Z","timestamp":1788420102000},"source":"Crossref","is-referenced-by-count":0,"title":["Quality Assessment of Systematic Reviews on Gluteal Augmentation Using a Measurement Tool to Assess Systematic Reviews (AMSTAR-2)"],"prefix":"10.1093","volume":"8","author":[{"given":"Elisa","family":"Bertulla","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edoardo","family":"Raposio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,3]]},"reference":[{"key":"2026101314162323000_ojag162-B1","doi-asserted-by":"publisher","first-page":"381e","DOI":"10.1097\/PRS.0000000000012437","article-title":"Gluteal augmentation with fat grafting: a systematic review and meta-analysis of complications and procedural factors","volume":"157","author":"Elsaftawy","year":"2026","journal-title":"Plast Reconstr Surg"},{"key":"2026101314162323000_ojag162-B2","doi-asserted-by":"publisher","first-page":"720","DOI":"10.1093\/asj\/sjaf208","article-title":"Characteristics and complications of combined implant and lipoplasty techniques in primary gluteal augmentation: a systematic review and meta-analysis","volume":"46","author":"Elsaftawy","year":"2026","journal-title":"Aesthet Surg J"},{"key":"2026101314162323000_ojag162-B3","doi-asserted-by":"publisher","first-page":"2719","DOI":"10.1007\/s00266-023-03458-0","article-title":"Effectiveness and role of using hyaluronic acid injections for gluteal augmentation: a comprehensive systematic review of techniques and outcomes","volume":"47","author":"Mortada","year":"2023","journal-title":"Aesthetic Plast Surg"},{"key":"2026101314162323000_ojag162-B4","doi-asserted-by":"publisher","first-page":"S342","DOI":"10.1097\/SAP.0000000000001765","article-title":"Differences in complication rates of gluteoplasty procedures that utilize autologous fat grafting, implants, or local flaps","volume":"82","author":"Asserson","year":"2019","journal-title":"Ann Plast Surg"},{"key":"2026101314162323000_ojag162-B5","doi-asserted-by":"publisher","first-page":"20e","DOI":"10.1097\/PRS.0000000000003439","article-title":"The ideal buttock size: a sociodemographic morphometric evaluation","volume":"140","author":"Heidekrueger","year":"2017","journal-title":"Plast Reconstr Surg"},{"key":"2026101314162323000_ojag162-B6","doi-asserted-by":"publisher","first-page":"1896","DOI":"10.1007\/s00266-022-03222-w","article-title":"What makes a beautiful buttock beautiful?
