To address this clinical challenge, we developed an anisotropic meniscus scaffold using three-dimensional (3D) bioprinting technology to promote functional regeneration. In this study, the scaffold was fabricated via 3D bioprinting, employing a composite of polyurethane and polycaprolactone polymers, meniscus derived decellularized extracellular matrix bioink, and mesenchymal stem cells (MSCs).\n                    <jats:italic>In vitro<\/jats:italic>\n                    , the bioprinted constructs, incorporating tissue-derived bioinks with region-specific stiffness, facilitated the differentiation of MSCs and extracellular matrix deposition in a manner that recapitulated the native anisotropic architecture of the meniscus.\n                    <jats:italic>In vivo<\/jats:italic>\n                    , the constructs demonstrated excellent chondroprotective effects and supported neo-meniscus formation in a canine model at 12 and 24 weeks post-implantation.
