Advancing the Tendinopathy Triad: Comment on "Tendinopathy: The Interplay Between Mechanical Stress, Inflammation,...

Building upon the integrative framework of tendinopathy proposed by Gehwolf et al.-which elegantly connects mechanical stress, inflammation, and vascularity-this commentary extends the discussion by introducing novel mechanistic insights and future research directions that move beyond the established triad. A paradigm shift is proposed toward spatiotemporal multi-omics deconstruction of tendon pathology, emphasizing the role of epigenetically driven cellular re-programming in tendon stem/progenitor cells and the emergence of neuro-immune-vascular niches as functional units sustaining chronicity. Furthermore, redox-mechanobiological integration through sensors such as TNIK and the potential of 4D-bioprinted smart biomaterials for chrono-specific therapeutic delivery are explored. By incorporating advanced computational approaches, including AI-powered digital tendon twins, a transformative roadmap is outlined for translating the homeostatic failure model into precisely targeted, mechanism-based diagnostics and therapies. This perspective aims to stimulate interdisciplinary innovation and position tendinopathy research at the forefront of musculoskeletal science.
