While China leads in total publication output, its relatively low centrality (0.06) combined with a low global institutional network density (0.0061) reveals a \u201chigh-output, low-integration\u201d pattern, indicating significant potential for enhanced international synergy. Key knowledge hubs are centered around institutions like Nanjing University of Chinese Medicine and Universidade da Coru\u00f1a, with leading scholars such as Blanco FJ and Li J driving the field\u2019s intellectual core. Keyword clustering identifies a three-dimensional thematic landscape: nutritional intervention (e.g., vitamin E), mechanistic exploration (e.g., cell senescence), and therapeutic investigation (e.g., ozone). The research evolution follows a clear trajectory of \u201cfoundational validation \u2192 mechanistic refinement \u2192 translational expansion,\u201d with current frontiers shifting from localized joint mechanisms toward systemic-local interactions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The field of KOA and oxidative stress is characterized by an internationally collaborative yet resource-fragmented research landscape. Its evolution follows a logic of initial foundational validation, followed by mechanistic refinement, and finally translational expansion. Future efforts should strengthen interdisciplinary collaboration and promote multicenter clinical translational research, which holds promise for developing more targeted and effective novel strategies for the diagnosis and treatment of KOA.<\/jats:p>\n
