Comparison of Vessel-Sparing vs Vessel-Ligation Surgery in Anterior Approach Total Hip Replacement Impact on Muscle Health and Patient Outcomes

What this Trial Is About

Researchers are investigating whether a blood vessel-sparing surgical technique during direct anterior approach total hip arthroplasty DAA THA can improve clinical outcomes compared to the standard vessel ligation method. This trial focuses on patients undergoing hip replacement and aims to determine if sparing the lateral femoral circumflex artery reduces muscle tenderness and the incidence of tensor fascia lata TFL tendinopathy. The study is a prospective, randomized, blinded clinical trial conducted at a single center, with a planned duration of at least three years or until enrollment exceeds the target sample size by 50% 100 patients. Participants will be randomly assigned to one of two groups one undergoing the vessel-sparing surgical procedure and the other receiving the standard vessel ligation technique. The feasibility of the vessel-sparing technique, including whether it can be successfully performed in about 60% of patients, will be observed. The trial will compare clinical outcomes such as the incidence of TFL tendinopathy, patient-reported hip function scores, and component placement on X-rays one year after surgery. During the study, patients will be monitored through follow-up assessments at one year post-surgery, including evaluations of TFL tendinopathy incidence, modified Harris Hip Score, Hip And Groin Outcome Score, Forgotten Joint Score, and Hip disability and Osteoarthritis Outcome Score. X-ray imaging will assess the placement of hip components. The success of the vessel-sparing technique will be assessed at the end of surgery. The entire participant involvement is designed to collect comprehensive data on surgical outcomes and patient-reported measures to understand the impact of the vessel-sparing approach.
