Further, the migration of the Avanteon stem over time will be assessed. Patients included are patients with hip osteoarthritis from 65-80 years old. The purpose of this study is to compare implant migration and early fixation of a hybrid hip replacement combining the uncemented ACE acetabular component and the cemented Avanteon femoral stem, by using CT based Radiostereometric Analysis, a new innovative method for evaluating implant migration. Our study may predict the long term survival of the implants used.\n\nParticipants will go through total hip arthroplasty, and be followed by CT-RSA, plain x-rays and patients reported outcome measures.",[100],"Hip Osteoarthritis",[102,103,104,105,106],", Total Hip Arthroplasty,","Total Hip Replacement","CT-RSA","CTMA","Migration study","2024-08-26",{"date":109,"type":110},"2024-08-28","ACTUAL",{"date":112,"type":110},"2024-08-25",{"date":114,"type":94},"2028-11-01",{"name":5,"class":6},1]
