Bone Remodeling Around a Trabecular Titanium Cup in Total Hip Arthroplasty
The goal of this randomized controlled trial is to measure the periprosthetic bone mineral density changes around a 3D-printed highly-porous titanium acetabular cup used in primary total hip arthroplasty compared to a standard hydroxyapatite/titanium plasma-sprayed acetabular cup up to 2-year follow-up.
