A 2-year prospective clinical and bone density evaluation, with a subset undergoing radiostereometric analysis, using the Absolut cemented stem.

Background: Total hip arthroplasty (THA) is common though the investigation of new prostheses requires a practical, step-wise introduction. This study reports the 2-year clinical results and periprosthetic bone mineral density (BMD) changes, along with a subset undergoing Radiostereometric analysis (RSA), in patients undergoing primary cemented THA using a new highly polished, double tapered, collarless femoral stem (Absolut).

Methods: Between August 2013 and December 2016, 47 patients with a mean age of 74.
