A ceramic body can be made by a method that includes providing an initial green body of ceramic (520/521); and machining the initial green body to provide a machined green ceramic body (530). The machined green ceramic body may be fired to provide a more finished ceramic body (540) and/or further processed to provide a finally finished ceramic body (550). As illustrations of the many possible, the ceramic body can be a femoral component (100) for a posterior stabilized knee implant or component body (101) for an artificial rotation device containing knee prosthesis. Zircona ceramic bodies are advantageously provided.
