Acetabular Polyethylene Wear and Acetabular Inclination and Femoral Offset
Abstract Restoration of femoral offset and acetabular inclination may have an effect on polyethylene ( PE ) wear in THA . We therefore assessed the effect of femoral offset and acetabular inclination ( angle ) on acetabular conventional ( not highly cross-linked ) PE wear in uncemented THA . We prospect ively followed 43 uncemented THAs for a minimum of 49 months ( mean , 64 months ; range , 49–88 months ) .  Radiographs were assessed for femoral offset , acetabular inclination , and  conventional PE wear . The mean ( ± st and ard deviation ) linear wear rate in all THAs was 0.14 mm/year ( ± 0.01 mm/year ) and the mean volumetric wear rate was 53.1 mm3/year ( ± 5.5 mm3/year ) . In THAs with an acetabular angle less than 45 ° , the mean wear was 0.12 mm/year ( ± 0.01 mm/year ) compared with 0.18 mm/year ( ± 0.02 mm/year ) in those with a reconstructed acetabular angle greater than 45 ° . Reproduction of a reconstructed femoral offset to within 5 mm of the native femoral offset was associated with a reduction in conventional PE wear ( 0.12 mm/year versus 0.16 mm/year ) . Careful placement of the acetabular component to ensure an acetabular angle less than 45 ° in the reconstructed hip allows for reduced conventional PE wear .
