| abstract |
The present invention relates to a method of manufacturing a joint replacement implant that has been processed and coated to have an aperture, wherein at least one layer of a biocompatible metal or alloy thereof is attached to the surface of the implant, Forming a surface. Next, a surface microstructure is formed on the implant surface. This is done by etching the implant surface, for example by an acid bath or plasma etching, or by attaching fine biocompatible particles to the implant surface. The thickness of the surface layer with apertures is in the range of 0.5 mm to 1.5 mm, and its porosity is at least 40%. |
