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 .
Bioactive cement or ceramic/porous coating vs. conventional cement to obtain early stability of the acetabular cup. Randomised study of 96 hips followed with radiostereometry.
Ninety patients ( 96 hips ) scheduled for THA were stratified to fixation of the acetabular component in three main groups of about equal size . Fluoride cement , porous coated press-fit cup with ceramic coating or Palacos cum Gentamicin cement were used . All patients received Spectron EF stem .  The migration of the cups and the femoral head penetration into the socket were measured with radiostereometric analysis . At 2 years the choice of fixation did not influence the migration or rotation of the cup .  Patients with compromised bone quality showed increased three-dimensional ( 3D or total ) migration . Proximal and 3D penetration rates were increased in cemented compared with the uncemented cups ( p<0.001 ) , which probably not could be related to the choice of fixation . Appearance of radiolucent lines was almost equal in the two cemented groups . Uncemented cups had less radiolucent lines at 2 years . Fluoride containing cement or uncemented fixation did not improve the early postoperative stability of the socket
