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 .
Methods We performed a systematic review using the Medline and Embase data bases to find evidence for the superiority of cemented or cementless acetabular components  on short- and long-term clinical and radiological parameters .
A comparison of polyethylene wear rates between cemented and cementless cups. A prospective, randomised trial.
We selected r and omly a consecutive series of 162 patients requiring hip replacement to receive either a cementless , hemispherical , modular , titanium acetabular cup or a cemented , all-polyethylene cup . These replacements were performed by two surgeons in four general hospitals . The same surgical technique was used and a 26 mm metal-head femoral component was used in every case . After exclusions , 115 hips were studied for differences in rates of wear and osteolysis . The mean clinical follow-up was eight years and the mean radiological follow-up , 6.5 years . The cementless cups  wore at a mean rate of 0.15 mm per year and the cemented cups at 0.07 mm per year . This difference was significant ( p < 0.0001 ) . Our findings in this mid-term study suggest that cementless cups  wear more than cemented cups
