Radiographic Stability of Hip Prosthesis Prior to Revision Surgery

The goal of this validation study is to compare the preoperative implant stability, assessed by Implant Movement Analysis (IMA), provocation dual CT scans, with the intraoperative stability evaluation in revision hip arthoplasty. The main question it aims to answer is: Does IMA reflect the intraoperative clinical evaluation of implant stability? Participants scheduled for revision hip arthoplasty will undergo IMA preoperativelly in addition to rutine clinical work up. During revision arthoplasty, a surgeon blinded to the IMA results will assess clinically the stability of the hip prosthesis. IMA will be compared with the intraoperative findings to assess IMAs sensitivity and specificity
