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 .
Matched-pair analysis of cemented and cementless acetabular reconstruction in primary total hip arthroplasty.
In a matched-pair study of primary total hip arthroplasty , 45 all-polyethylene cemented acetabular components were compared with 45 cementless , hemispheric , titanium acetabular components .  At 9 to 12 years , 1 of the cemented acetabular components was revised for aseptic loosening , and 14 ( 31 % ) were radiographically loose . Nine ( 20 % ) cemented acetabular components had pelvic osteolysis . In the cementless acetabular component group , 2 well-fixed components were revised . No components were radiographically loose , and 3 ( 7 % ) had pelvic osteolysis . Thirty-eight ( 97 % ) of the patients in each group were satisfied with the surgery . The clinical results of the cemented and cementless components were excellent . The cementless components had less loosening ( P < .001 ) than the cemented components
