    摘要: Compositions and methods are provided for treating joint conditions, such as osteoarthritis and/or the pain associated therewith. The compositions and methods utilize a first component, namely hyaluronic acid (“HA”), in combination with at least one stabilizer. The composition can include a stabilizer that increases the stability and shelf-life of the HA. In another embodiment, the compositions and methods can also include an additional component, such as one or more glycosaminoglycans (“GAG”) or GAG precursors. Examples of GAGs or GAG precursors can include chondroitin sulfate (“CS”), dermatan sulfate, heparin, heparan sulfate, keratan sulfate, and glucosamine (“GlcN”).

    摘要: A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to γ ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is evaporated in order to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.
