NCT04113759

Brief 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.

Study Arms (2)

Control Group

PLACEBO COMPARATOR

The control group will receive sham BFR, in which a non-occlusive pressure is applied with the cuff. The exercises performed will be identical to the BFR group.

Behavioral: Sham BFR Rehabilitative Therapy

BFR Postoperative Rehabilitation

EXPERIMENTAL

The experimental group will receive BFR postoperative rehabilitation, which will involve performing a series of blood flow restriction exercises identical to the control group.

Behavioral: Blood Flow Restriction Rehabilitative Therapy

Interventions

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.

BFR Postoperative Rehabilitation

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.

Control Group

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Adult patients 18-40
  • English-speaking

  • Patients lacking decisional capacity
  • Patients with a history of deep vein thrombosis, pulmonary embolism, or known clotting disorder or hypercoagulable state
  • Pregnant or breast-feeding women. Pregnancy as determined by a positive pregnancy test prior to procedure. Females of childbearing potential must agree to use an acceptable birth control method during study participation.
  • Worker's compensation patients
  • Any clinically significant finding that would place the patient at health risk, impact the study, or affect the completion of the study
  • Any psychiatric illness that would prevent comprehension of the details and nature of the study and interfere with follow-up clinic visits
