3D printed scaffolds for rotator cuff repair
Recurrent rotator cuff tears cost ~NZ$100m pa and heal poorly into functionally compromised fibrotic scar tissue (Fig 2). Tissue engineering has the potential to contribute to successful tendon healing; using a biomaterial scaffold inserted at the site of injury, providing temporary mechanical support, while ultimately enhancing tissue regeneration. We utilise advanced 3D Printing techniques to develop synthetic degradable scaffolds with hierarchical structures for rotator cuff repair. Due to unique processing technique, these flexible scaffolds have shown promising mechanical properties.
