| 摘要 |
The present invention is directed to a polymeric prosthesis precoated with a bone cement compatible polymer. The bone cement compatible polymer coating, which can be polymethyl methacrylate, is bonded to the outer surface of the prosthesis. For instance, in one embodiment, the bone cement compatible polymer coating is believed to be copolymerized with the polymeric prosthesis. Once bonded to a polymeric prosthesis in accordance with the present invention, the precoat strengthens the interface between a bone cement and a prosthesis when the prosthesis is later implanted. The precoat also decreases the likelihood that the prosthesis will loosen and break away from the cement over time. The polymeric implant product of the present invention is particularly well suited for use as an acetabular cup or a tibia plateau in replacing hip joints and knee joints respectively.
