Abstract Click to copy section linkSection link copied! Full-thickness osteochondral defects demand the concurrent restoration of cartilage and subchondral bone. Here, hyaluronic acid methacrylate (HAMA) scaffolds were three-dimensional (3D)-printed with in situ photocuring and formulated with glucosamine (GlcN) at different concentrations; 5 mg·mL–1 was identified as optimal. This formulation preserved print fidelity and curing, while yielding a compliant, continuous network.
