Postoperative Blood Flow Restriction Training Following Hip Arthroscopy: A Randomized Clinical Trial
Rush University Medical Center
Summary
This study will be a prospective randomized, double-blinded, placebo-controlled trial of patients undergoing primary hip arthroscopy for FAIS and/or labral pathology. All patients who sign the consent form will be enrolled in the study and randomized to one of the two treatment arms. Follow-up will take place at 1-month, 3-months, 6-months, and 1-year.
Description
The investigators propose using standardized strength testing, serial quadriceps measurements, and MRI to assess the efficacy of BFR training in increasing muscle hypertrophy following hip arthroscopy. Investigators will perform a randomized double-blinded placebo-controlled controlled trial of patients undergoing primary hip arthroscopy. Quadriceps strength will be measured with dynamometers at 3, 6, and 12 month time points, with Biodex strength testing at 6 and 12 months, postoperatively. Additionally, standardized circumferential leg measurements to assess quadriceps hypertrophy will be pe…

Interventions
- BehavioralBlood Flow Restriction Rehabilitative Therapy
BFR cuffs placed at the proximal thigh, just inferior to the greater trochanter. Inflation time not to exceed 20 minutes. One BFR session per treatment. BFR exercise dosage: 4 sets of the following repetitions 30, 15, 15, 15, 30 second rest between sets, 1 min rest between exercises. Progress exercise if pain \<2/10 on VAS and RPE \<5 on 0-10 scale. (Heerey et al), and no break down in form.
- BehavioralSham BFR Rehabilitative Therapy
The schedule, type of exercises, repetition ranges, and other physical therapy interventions will be the same as the BFR experimental group - however a non-occlusive pressure will be applied with the cuff in the control group.
