Excellent results have been observed with trabecular titanium (TT) which mimic the structure of trabecular bone. The aim of our study is to evaluate the mid-to-long-term outcome in revision surgery due to severe acetabular defect using TT cups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods:<\/jats:title>\n                    <jats:p>We performed a retrospective analysis of patients undergoing revision with Paprosky IIa or higher using modular TT cup. We evaluated clinical outcomes using FJS, WOMAC, OHS, and WORQ. Radiolucency and integration were used to assess radiographic results.

In regard to diagnosis, patients were affected by: aseptic loosening (55,3%); debris-induced osteolysis (18%); infection (11,5%); PPF (7.8%); and dislocation (7.4%). At the final floow-up, we documented the following: OHS 35.06\u2009\u00b1\u20094,31; WORQ 26.69\u2009\u00b1\u20094.18; WOMAC 27.59\u2009\u00b1\u20097.57; FJS of 55.3\u2009\u00b1\u200910.39 (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      -value\u2009&lt;\u20090.005). Complication rate was 9.2%. The most frequent complication was dislocation, followed by deep infection and aseptic loosening.
