Studies reporting genetic associations with aseptic loosening or osteolysis in THA\/TKA were included. Quality was assessed via Q-Genie. Pooled odds ratios (random-effects) were computed for loci with \u22653 independent studies (TNF-\u03b1 -308G\u2009&amp;gt;\u2009A, IL-6 -174G\u2009&amp;gt;\u2009C).

IL-1RN VNTR 498\u00a0bp allele conferred ~\u20094-fold risk in atopic patients. Variants in RANK, KREMEN2, OPG, SFRP1, TIRAP, and BCL2 were also associated. GNAS1 and CALCA showed no association.
