Malahias MA, et al. - Investigators performed a systematic review to analyze the utility and safety of highly porous titanium acetabular components in primary and revision total hip arthroplasty. They selected 16 studies recruiting a total of 11,366 cases(60% females, 2-7 years mean follow-up). They searched the US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews for publications utilizing the following keywords: “titanium” OR “highly-porous” AND “titanium” OR “acetabular” AND “trabecular” AND “titanium”. The moderate-quality evidence was found to show that the use of highly porous titanium acetabular components in primary and revision THA cases is correlated with satisfactory clinical outcomes in the short and medium-term, without displaying any evidence of cup migration or radiolucency. Yet, no evidence was noted regarding the long-term survivorship of these components, future study of higher quality is needed to generate more evidence-based conclusions regarding the longevity of highly porous titanium acetabular implants compared with conventional titanium counterparts.
