Comparison of Surface Characteristics of Retrieved Cobalt-Chromium Femoral Heads With and Without Ion Implantation

Abstract Nitrogen ion implantation of CoCr is reported to produce increased surface hardness and a lower friction surface. Femoral heads with and without ion implantation retrieved from 1997 to 2003 were evaluated for surface roughness (average surface roughness [Ra], mean peak height [Rpm], and max...
