Development of artiﬁcial articular cartilage
The present study describes the development of artiﬁcial articular cartilage on the basis of mimicking structural gel properties and mechanical gel properties of natural articular cartilage. It is synthesized from PVA/Si nanocomposite containing 20% Tetra ethoxy silane (TEOS) by sol–gel method. Mechanical strength of Poly(vinyl alcohol), PVA is improved up to 35 MPa. Manufacturing method is adopted considering colloidal stability of nano silica particle in PVA sol at speciﬁc pH = 1. An adhesive is also prepared from PVA/Si nanocomposite containing 40% TEOS for ﬁrm attachment of artiﬁcial articular cartilage on underlying bone with high bond strength.
