Efficacy of Preoperative Education and Mini-invasive Surgery for Total Hip Replacement

We propose to evaluate a preoperative education of the patient and a new surgical technique (the mini-invasive THR) that could reduce the time to achieve functional independence. The primary objective of the trial is to assess the time to reach functional independence after total hip replacement depending on the treatment groups: preoperative education versus no preoperative education and mini-invasive procedure versus standard procedure. The study hypothesis is that education and mini-invasive procedure will reduce the time to reach functional independence. This is a prospective trial with a double randomization.
