Abstract
A method of attaching an implant to a bone, the implant comprising a hydrated polymer comprising a lubricious hydrated surface and an attachment surface comprising accessible chemical functional groups. The method includes the steps of treating the implant or the bone with an isocyanate-containing compound; placing the attachment surface in apposition to the bone; and allowing the isocyanate-containing compound to cure to bond the implant to the bone. The invention also includes a medical implant having a hydrated polymer comprising an attachment surface comprising a thermoplastic material, the hydrated polymer having an interpenetrating polymer network with at least two polymers, the hydrated polymer having a low coefficient of friction on at least one surface.
