3D‐Printed Porous Titanium Alloy Scaffolds Incorporated With Tetramethylpyrazine‐Loaded Composite Hydrogels Enhance Angiogenesis and Bone Repair for Femoral Head Osteonecrosis
Randomized trial shows improved bone repair and angiogenesis in femoral head osteonecrosis, suggesting a novel scaffold approach.
Key Points
The aim of this study is to evaluate the efficacy of a 3D-printed titanium alloy scaffold with drug-release capabilities in treating osteonecrosis of the femoral head.
Developed a multifunctional composite scaffold with porous titanium alloy and dual-release hydrogel system.
Conducted in vitro assessments for biocompatibility and differentiation capabilities.
Utilized a rat model to assess in vivo bone repair and angiogenesis effects.
In vivo studies indicated a significant increase in new bone volume and density, with enhanced angiogenesis observed.
Promoted osteogenic differentiation and angiogenic tube formation in vitro.
Sustained drug release facilitated recovery and repair in the femoral head area.
