A second-generation cementless total hip arthroplasty mean 9-year results.
Two hundred fifty-eight primary total hip arthroplasties in 231 patients were implanted using a circumferentially, proximally porous-coated, collared femoral component and a cementless, hemispherical, porous-coated acetabular component and followed up for a mean of 9 years (5-14 years). Four femoral components were revised (2 stems for infection and 2 stems for aseptic loosening). One additional femoral component was radiographically loose at last follow-up. Nine hips underwent acetabular revision (4 for instability, 2 for infection, 2 for loosening, and 1 for osteolysis). Ten-year survivorship with revision or loosening of any component as the end point was 92%; with femoral component aseptic loosening as end point, survivorship was 98%; with acetabular aseptic loosening as the end point, survivorship was 99%. Osteolysis was identified in 26 hips (13%).
