Abstract
Despite the advantages for cementless tantalum fixation shown in the study by FernandezFairen and colleagues current evidence supports cemented fixation for TKA The most valid evidence for the best mode of fixation can be collected in large multicenter or register studies that include all patients or at least consecutive patients Rand et al 7 performed a survivorship analysis of more than 11000 TKAs at 10 years Results of the study showed a 92 survival rate with cemented implant fixation versus 61 with cementless implant fixation p 0001 Gioe et al 5 evaluated more than 5700 TKAs for different modes of fixation and found that cementless fixation had the lowest survival rate compared to cemented fixation In fact to my knowledge no multicenter or register studies in the literature favor cementless fixation when compared with cemented fixation A recent metaanalysis of current randomized controlled trials and observational studies 4 tended toThe author certifies that he or a member of his immediate family has no funding or commercial associations eg consultancies stock ownership equity interest patent/licensing arrangements etc that might pose a conflict of interest in connection with the submitted article
