Mechanical-chemical Attachment of the Artificial Cartilage (PVA-hydrogel) to the Metal Substrate (or Underlying Pone)

PVA-hydrogel is attached to the metal fibre mesh by means of micro-mechanical interlock method at first, then the surface of metal fibre mesh is bonded to the underlying bone by the bone cement (PMMA). In this way, the artificial cartilage can be firmly attached to the underlying bone (or metal substrate). Microstructure analysis and mechanical tests show that the attachment between artificial cartilage and the metal substrate is firm.
