Why the study?

The study evaluated the effect of blood flow restriction therapy conducted both before and after ACL reconstruction on early quadriceps strength and patient-reported outcomes.

Does blood flow restriction therapy improve early quadriceps strength and patient reported outcomes in patients undergoing ACL reconstruction?

Population

43 patients presenting with an ACL tear

Comparison

Blood flow restriction therapy before and after ACL reconstruction vs control

Design

Randomized controlled trial

Follow-up

6 weeks post-surgery

Overview

BFR improved early PROs without quadriceps strength gains after ACLR; extends pre/post-op evidence but leaves strength-PRO disconnect open for further study.

Structured PICO

Does blood flow restriction therapy improve early quadriceps strength and patient reported outcomes in patients undergoing ACL reconstruction?

P
Population
43 patients (24 male, 19 female; age 27.6 ± 11.88 years) presenting with an anterior cruciate ligament (ACL) tear.
I
Intervention
Blood flow restriction (BFR) therapy utilizing a pneumatic cuff set to 80% of limb occlusion pressure placed over the proximal thigh during preoperative exercises (4-5 days per week for two weeks) and during standard post-ACL reconstruction physical therapy.
C
Comparator
Standard preoperative exercises and post-ACL reconstruction physical therapy without the use of blood flow restriction.
O
Outcome
Early quadriceps strength (peak force, average force, time to peak force) and patient reported outcomes (PROMIS-PF, IKDC scores) at 6 weeks post-surgery.patient reported

Blood flow restriction therapy before and after ACL reconstruction improves early patient-reported outcomes at 6 weeks, though it does not significantly increase objective quadriceps strength in the short term.

Limitations

  • Long term follow up is needed to determine if differences arise in quadriceps strength between groups.
