Polyethylene wear is the primary limiting factor in the functional behavior and consequent longevity of a total hip arthroplasty (THA). This retrospective study reviewed the clinical and radiographic data of 77 consecutive THAs comparing in vivo polyethylene wear of two similar acetabular cup liners. Minimum follow-up was 7 years (range 7\u201315). The incidence of measurable wear in a group of machined liners sterilized with ethylene oxide and composed of GUR 1050 stock resin was significantly higher (61%) than the compression-molded, GUR 1020, O\n                    <jats:sub>2<\/jats:sub>\n                    -free gamma irradiation sterilized group (24%)\n                    <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                      <mml:mrow>\n                        <mml:mo stretchy=\"false\">(<\/mml:mo>\n                        <mml:mrow>\n                          <mml:mi>P<\/mml:mi>\n                          <mml:mo>=<\/mml:mo>\n                          <mml:mn>0.0004<\/mml:mn>\n                        <\/mml:mrow>\n                        <mml:mo stretchy=\"false\">)<\/mml:mo>\n                      <\/mml:mrow>\n                    <\/mml:math>\n                    .
