A best evidence analysis for complications , wear , osteolysis , migration and clinical scores showed no superiority for either cemented or cementless socket in the RCTs .
A best evidence analysis for non RCT studies revealed better osteolysis , migration properties and aseptic loosening survival for cementless sockets ; however , wear and overall survival favoured the cemented sockets .
Purpose Total hip arthroplasty has been a very succesful orthopaedic procedure .

Migration of acetabular components, inserted with and without cement, in one-stage bilateral hip arthroplasty. A controlled, randomized study using roentgenstereophotogrammetric analysis.
Twenty-one patients who had primary osteoarthrosis were managed with a bilateral total hip arthroplasty with insertion of a Charnley femoral component . In each patient , one hip was r and omly allocated to have a Harris-Galante acetabular component inserted without cement , and the contralateral hip was treated with an all-polyethylene Charnley acetabular component fixed with cement . The clinical result was satisfactory in all patients . All forty-two hips were followed , with respect to migration of the acetabular component , with use of roentgenstereophotogrammetric analysis for a median of twenty-seven months ( range , twenty-three to forty-nine months ) . Each patient served as his or her own control . Maximum migration in any direction was 1.7 and 2.1 millimeters , and maximum rotation was 2.2 and 2.0 degrees for the Harris-Galante and Charnley acetabular components , respectively . There was no significant difference in migration between the two design s of acetabular components ( p = 0.98 , p = 0.75 , and p = 0.06 for the transverse , longitudinal , and sagittal axes , respectively ) . However , the Harris-Galante acetabular components  rotated significantly more than the Charnley acetabular components around two of the three axes ( p = 0.008 , p = 0.08 , and p = 0.03 for the transverse , longitudinal , and sagittal axes , respectively ) . The Charnley hip implant has been used clinical ly for a long time , with successful results . Comparison of new design s of implants with the Charnley prosthesis is therefore important . Roentgenstereophotogrammetric analysis provides a potential for detection of problems with fixation at an early stage rather than after long-term follow-up . No major difference in terms of skeletal fixation was found between the two design s of components after short to medium-term follow-up
