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 .
The results of the titanium-coated RM acetabular component at 20 years: a long-term follow-up of an uncemented primary total hip replacement.
In a prospect i ve study , 93 unselected consecutive uncemented hip arthroplasties were performed in 80 patients using the  titanium-coated RM acetabular component and the CLS femoral component .  The mean age of the patients at operation was 52 years ( 28 to 81 ) . None were lost to follow-up . In the 23 patients who had died ( 26 hips ) only one acetabular component had been revised . In the 57 living patients ( 67 hips ) , 13 such revisions had been performed . Of the 14 revisions , seven were for osteolysis , five for loosening and two for infection . Survival analysis of this implant showed a total probability of survival of 83 % ( 95 % confidence interval 73 to 90 ) , with all revisions as the endpoint , and a probability of 94 % ( 95 % confidence interval 87 to 98 ) with revision for aseptic loosening as the endpoint , indicating reliable long-term fixation of the titanium-coated RM acetabular component
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 .
