[The mechanical chemical attachment of artificial cartilage (PVA-hydrogel) to metal substrate (or underlying bone)].
The biocompatibility and tribological characteristics of PVA-hydrogel are excellent, but it is very difficult to make the artificial cartilage material (PVA-hydrogel) attach to the underlying bone. In this study, PVA-hydrogel is attached to the metal fibre mesh by means of micro-mechanical interlock methods 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.
