This biomaterial demonstrated improved mechanical properties and enhanced osteoinduction and osteoconduction in several in vitro and in vivo studies. The aim of this study was to assess Trabecular Titanium osseointegration by measuring periacetabular changes in bone mineral density (BMD) with dual-emission X-ray absorptiometry (DEXA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>89 patients (91 hips) underwent primary total hip arthroplasty (THA) with acetabular Trabecular Titanium cups. Clinical (Harris Hip Score (HHS), SF-36) and radiographic assessment were performed preoperatively, and postoperatively at 7 days and at 3, 6, 12 and 24 months. DEXA analysis was performed only postoperatively, using the BMD values measured at 7 days as baselines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After an initial decrease from baseline to 6 months, BMD increased and progressively stabilised in all 3 regions of interest (ROIs). Median (IQR) HHS and SF-36 increased from 48 (39-62) and 49 (37-62) preoperatively to 99 (96-100) and 86 (79-92) at 24 months, indicating a considerable improvement in terms of pain relief, functional recovery and quality of life. BMD patterns and radiographic evaluation showed evident signs of periacetabular bone remodelling and osseointegration; all cups were stable at the final follow-up without radiolucent lines, loosening or osteolysis. No revisions were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>After an initial reduction in periacetabular BMD, all 3 ROIs exhibited stabilisation or slight recovery.
