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 .
The optimal fixation method of the acetabular component however , has not yet been defined .

Osteolysis in cemented versus cementless acetabular components.
A prospect i ve , r and omized , double-blind , clinical trial comparing cemented with cementless total hip arthroplasty  was performed to compare the prevalence and pattern of acetabular osteolysis . Both groups were similar before surgery . Acetabular components were metal-backed , titanium implants . Twenty-eight-millimeter modular femoral heads with titanium femoral stems were used . At a minimum 2-year and mean 4-year follow-up period ( range , 2 - 6 years ) , 224 patients had clinical and radiographic data available . There was no significant difference in the prevalence of acetabular osteolysis between cemented ( 5 % ) and cementless ( 9 % ) fixation . With or without cement , the use of a titanium femoral head led to osteolysis within a relatively short period after surgery in almost all of the cases , although this was not significant . The pattern of acetabular osteolysis was different . Progressive osteolysis occurred predominantly in acetabular zone 1 in the cemented group and zone 2 in the cementless group . Cementless fixation of acetabular components has been advocated in an attempt to minimize osteolysis that may occur in cemented total hip arthroplasty . This study found no difference in the prevalence of acetabular osteolysis between the two groups
