Objective: The primary goal of this article is to perform a systematic literature review for randomized controlled trials in which cemented and cementless acetabular components are compared and to find evidence for the best acetabular fixation interface.
Methods: In order to assemble all relevant literature we searched the most common data bases of published medical literature: Medline and the Cochrane database of randomized controlled trials. Search strategy: acetabul* and cement* and cementless or uncemented or non cemented. Two authors reviewed all selected articles for relevance en used the van Tulder and Jaddad checklist to asses methodological quality.
Results and conclusions: The search revealed 1114 articles from which we isolated 15 randomized controlled trials in which cemented and cementless acetabular components were compared. A best evidence analysis for wear, osteolysis, migration and clinical scores showed no superiority for either cemented or cementless sockets.
Although our search could not provide evidence for the superiority of either cemented or cementless acetabular fixation, the long term follow-up studies reported in literature are providing us with data that cementless acetabular fixation is a good alternative to cemented fixation of the socket.
