What this Trial Is About
This research aims to compare two surgical techniques for treating iliopsoas tendinopathy caused by impingement between the iliopsoas tendon and the prosthetic cup in patients who have undergone total hip replacement. The study evaluates clinical improvement using the Oxford Hip Score measured at baseline, 2 months, and over 12 months after surgery. It is a randomized, single-blind, comparative trial conducted at a single center. Participants will undergo endoscopic tenotomy surgery of the iliopsoas tendon, performed either at the lesser trochanter or at the acetabular notch. Patients are randomly assigned to one of these two groups by drawing lots. The surgery is carried out under general anesthesia with standardized multimodal pain management, and all other surgical approaches and postoperative care remain consistent between groups. During the study, patients will be assessed with the Oxford Hip Score before surgery, at 2 months, and at more than 12 months after the procedure to measure clinical improvement. The study monitors patient outcomes and recovery following the surgery. Participation involves preoperative consultation, surgery, and follow-up assessments over at least one year to evaluate the treatment effect.
