In recent years, one common cure for losses in joint function caused by osteoarthritis or rheumatoid arthritis is replacement with an artificial joint. For this reason, it is necessary to add osteoconductivity to artificial joint component surfaces that make contact with bone, thereby reducing the period of time necessary to fixate the bone tissue and the artificial joint component. With the intent of efficiently machining the joint shape by electrical discharge machining (EDM) and simultaneously formation of a surface with osteoconductivity, this study discusses the possibility of adding osteoconductivity to a titanium EDMed surface.
