Overview
Brief Summary
Interest of a highly cross-linked polyethylene acetabular component doped with vitamin E in total hip arthroplasty of the young and active subject.
Detailed Description
A single-centre, prospective, randomised, single-blind, comparative study of two parallel groups of patients undergoing total hip arthroplasty: * Group 1: Prosthesis with a second-generation ceramic-on-highly cross-linked polyethylene (CoPXE) couple. * Group 2: Prosthesis with ceramic-on-ceramic (CoC) torque.

Outcomes
Primary Outcomes
five-year wear thickness of the two friction pairs
Time Frame: Year 5
The primary endpoint is the five-year wear thickness of the two friction pairs (CoPXE versus CoC) after total hip arthroplasty. Wear thickness is the measurement of the penetration of the femoral head into the acetabular component. This measurement will be performed on frontal pelvic radiographs centred on the pubic symphysis using the semi-automatic computer-assisted technique described by Martell
