Randomized Study of Blood Flow Restriction Therapy After Hip Arthroscopy for Labral Tear and Femoral Acetabular Impingement

What this Trial Is About

Researchers are evaluating the use of blood flow restriction BFR therapy to improve muscle strength and size after primary hip arthroscopy for femoroacetabular impingement syndrome FAIS andor labral pathology. This randomized, double-blinded, placebo-controlled trial aims to measure the effects of BFR on quadriceps muscle hypertrophy and strength during rehabilitation. The study includes adult patients aged 18 to 40 who are undergoing their first hip arthroscopy and will follow them for up to one year after surgery. Participants will be randomly assigned to one of two groups. The experimental group will receive BFR postoperative rehabilitation, which involves performing specific exercises with BFR cuffs placed on the thigh to restrict blood flow during exercise sessions lasting up to 20 minutes. The control group will perform the same exercises but with sham BFR, where non-occlusive pressure is applied. Both groups follow the same exercise schedule and repetitions, with progression based on pain and exertion levels. Throughout the study, participants will be assessed at 1, 3, 6, and 12 months after surgery. Assessments include quadriceps strength testing with dynamometers and Biodex machines, standardized thigh circumference measurements, and a hip MRI at 6 months to evaluate muscle size and appearance. Patient-reported outcomes such as hip function scores, pain scales, and return to sportwork questionnaires will also be collected. Researchers will monitor rates of reinjury and overall recovery progress during these visits.
