RESULTS The meta- analysis did not reveal any effect of the type of acetabular component fixation on either survivorship or revision rate .
The preference for cementless acetabular components on the basis of improved survivorship is not supported by the published evidence .
Although concerns regarding aseptic loosening of cemented acetabular components may have led North American surgeons toward the nearly exclusive use of cementless acetabular components , the available literature suggests that the fixation of cemented acetabular components is more reliable than that of cementless components beyond the first postoperative decade
BACKGROUND The use of cementless acetabular components in total hip arthroplasty has gained popularity over the past decade .
Most total hip arthroplasties being performed in North America currently use cementless acetabular components .
The objective of this systematic review and meta- analysis was to compare the survivorship and revision rate of cemented and cementless acetabular components utilized in total hip arthroplasty .
Long-term survivorship of the Charnley Elite Plus femoral component in young patients.
We studied prospect ively the long-term results of the Charnley Elite-Plus femoral stem in 184 consecutive young patients ( 194 hips ) . There were 130 men and 54 women with a mean age of 49.1 years ( 21 to 60 ) . The predominant diagnosis was osteonecrosis of the femoral head ( 63.6 % , 117 patients ) .  Clinical and radiological evaluation was undertaken at each follow-up . The mean follow-up was 11.2 years ( 10 to 12 ) . The mean pre-operative Harris hip score was 43.4 ( 12 to 49 ) which improved to 91 ( 59 to 100 ) at the final follow-up . The survival of the femoral stem  at 12 years was 99 % with revision as the end-point . The mean annual linear wear of the polyethylene liner was 0.17 mm ( 0.13 to 0.22 ) . The prevalence of acetabular osteolysis was 10.8 % ( 21 hips ) and osteolysis of the calcar femorale 12.9 % ( 25 hips ) . A third-generation cementing technique , accurate alignment of the stem and the use of a 22 mm zirconia head were important factors in the prevention of aseptic loosening of the Elite Plus femoral stem in these high-risk young patients
