Clinical Improvement Obtained by Endoscopic Ilio-Psoas Tenotomy (Lesser Trochanter Versus Acetabular Notch)

This is an interventional, comparative, randomized study, in 2 parallel groups, single-blind (the patient does not know which technique he will benefit from, the surgeon will carry out the surgery and will therefore be informed of the result of the randomization ) and monocentric.

Comparative prospective cohort study of an endoscopic tenotomy surgery of the iliopsoas tendon at the level of the lesser trochanter versus at the level of the acetabular notch, in the context of anterior pain for impingement between the iliopsoas tendon and the prosthetic cup in patients after Total Hip Prosthesis.

The study will be proposed to the patient during the preoperative consultation. Patients eligible for surgery will be offered the study. After a reflection period of at least 15 days, patients who agree to participate in the study will be included. Randomization will be done by drawing lots to decide whether the endoscopic tenotomy will be performed at the level of the lesser trochanter or at the level of the acetabular notch. The surgery will be performed under general anesthesia with standardized multimodal analgesia. Whatever the techniques, the approaches, the instruments to perform the procedure and the postoperative course will be identical, as in usual practice.
