These trends threaten the core principles of objectivity, reproducibility, and transparency. This editorial highlights two categories of threats: (1) external pressures, such as AI misuse and metric-driven publishing models, and (2) internal systemic flaws, including the <em>‘publish or perish’</em> culture and methodological fragility. Mega-journals, characterized by high-volume publishing and broad interdisciplinary scopes, improve accessibility and accelerate dissemination. However, the emphasis on publication volume might weaken the rigor of peer review. To navigate these challenges, the authors propose a balanced approach that harnesses innovation without compromising scientific integrity. Proposed solutions include mandating AI transparency through frameworks like CONSORT-AI, and redefining impact metrics to emphasize reproducibility, mentorship, and societal impact alongside citations. Scientific journals should promote career opportunities based less on publication quantity and more on quality. Global cooperation, via initiatives like the San Francisco Declaration on Research Assessment (DORA) and the Committee on Publication Ethics (COPE), is essential to standardize ethics and address resource disparities. This editorial proposes solutions for researchers, journals, and policymakers to realign academic incentives and uphold the ethical foundation of the science. By fostering transparency, accountability, and equity, the scientific community can preserve its ethical foundations while embracing transformative tools—ultimately advancing knowledge and serving society.</div></div><div><h3>For clinical trials</h3><div>n/a.</div></div><div><h3>Level of evidence</h3><div>V.</div></div>","PeriodicalId":36847,"journal":{"name":"Journal of ISAKOS Joint Disorders & Orthopaedic Sports Medicine","volume":"17 ","pages":"Article 100940"},"PeriodicalIF":3.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147491924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to model and mechanically characterize how radial tears alter contact stress distribution using solid-mechanics principles and finite element analysis (FEA), and to determine whether anatomic repair restores hoop-stress continuity.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;A three-dimensional FEA model of a healthy knee was reconstructed from high-resolution 3-T magnetic resonance imaging (MRI).
