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 .
Early radiographic results comparing cemented and cementless total hip arthroplasty.
In a r and omized clinical trial of cemented and cementless total hip arthroplasty , 147 patients ( 76 cemented , 71 cementless ) have had a minimum 4-year clinical and radiographic follow-up evaluation . No revisions have been done in either group . Two cemented acetabular components were considered definitely loose and 18 were probably loose ; 7 cemented stems were possibly loose at last follow-up examination . One cementless socket was considered unstable . Although cementless femoral component subsidence occurred in 10 cases , the sinkage always stabilized within 6 months , and no stem was considered unstable at last follow-up examination . Significant femoral bone resorption was rare , and so-called " spot welds " were uncommon using this titanium stem .  Distal cortical hypertrophy was common , but the cause is uncertain . Osteolysis was seen around 10 cementless and 6 cemented sockets . A small area of lysis occurred in the proximal medial femoral neck in 15 cemented stems and 1 cementless stem . No cases of distal femoral lysis were seen in either group . Despite excellent clinical results with no difference between groups , the high rate of early radiographic failure of this metal-backed acetabulum should preclude its use . Osteolysis will continue to be a problem in both groups , and its prevention should remain the focus of future studies
