The Ace Avanteon Study - A Randomized Controled Trial

Sponsor: Helse Møre og Romsdal HF

Summary

The goal of this randomized controled trial is to compare if using of ancillary screws yields equal results as no use of ancillary screws in the ACE acetabulum cup of a total hip arthroplasty. 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. Participants will go through total hip arthroplasty, and be followed by CT-RSA, plain x-rays and patients reported outcome measures.
