Ultrasound-Guided Psoas Tenotomy for Ilio-Psoas Conflict After Total Hip Replacement

What this Trial Is About

This research aims to evaluate ultrasound-assisted psoas tenotomy in patients experiencing ilio-psoas conflict after total hip replacement. The ilio-psoas conflict is a common complication often related to mispositioning of the acetabular prosthetic component that irritates the ilio-psoas tendon. The study is designed to assess whether this ultrasound-guided procedure is feasible and how it impacts pain and functional outcomes compared to existing surgical methods. The procedure studied is a tenotomy of the ilio-psoas tendon performed under ultrasound guidance using a specific kit and a 3 mm Acufex hook blade. Patients will be under general anesthesia in a supine position with the hip extended 15 to 20 degrees. This approach aims to reduce scar tissue and simplify the surgical setup by avoiding more complex arthroscopic equipment. The study will not compare multiple groups but will focus on patients indicated for this tenotomy technique. Participants will be assessed for the success of the ultrasound-guided tenotomy three weeks after surgery, along with detailed pain evaluations at several points before and up to six months after the operation. Functional scores including the Oxford Hip Score, Harris Hip Score, and others will be measured at baseline and follow-up visits. Researchers will also monitor surgical parameters, complications, hospital stay length, scar healing, quality of life, patient satisfaction, and the need for rehabilitation over six months. Total participation will span at least six months post-surgery with multiple assessments to track outcomes and safety.
