Does Blood Flow Restriction Training Improve Quadriceps Function After Arthroscopic Knee Surgery?

Does Blood Flow Restriction Training Improve Quadriceps Function After Arthroscopic Knee Surgery? A Randomized Clinical Trial

Sponsor

The University of Texas Health Science Center, Houston

Enrollment

150 participants

Start Date

Nov 21, 2017

Study Type

INTERVENTIONAL

Conditions

ACL reconstruction Quadriceps Atrophy

Summary

The purpose of this study is to evaluate the effectiveness of physical therapy (PT) plus BFR training compared to PT alone (without BFR training) after ACL reconstruction in patients who require extended limited weight bearing through assessment of patient reported outcomes and functional testing. The hypothesis is that PT plus BFR training will mitigate the loss of quadriceps muscle cross-sectional area, strength, and function while also improving early clinical and functional results.

Eligibility

Min Age: 14 YearsMax Age: 55 Years

Plain Language Summary

Simplified for easier understanding

This study is investigating whether blood flow restriction (BFR) training — a technique that uses a cuff to reduce blood flow during low-intensity exercise — can improve quadriceps (thigh muscle) strength and function after knee surgery. Muscle weakness after ACL reconstruction is a major barrier to recovery and returning to sports. You may be eligible if... - You are between 14 and 55 years old - You underwent ACL reconstruction along with a meniscus or cartilage restoration procedure - You followed modified weight-bearing restrictions after surgery - You plan to return to recreational or competitive sports You may NOT be eligible if... - You are unable to attend physical therapy - You are pregnant - You have cancer, a fracture, peripheral vascular disease, or a history of deep vein thrombosis (DVT) Talk to your doctor to see if this trial is right for you.

Interventions

DEVICEBlood flow restriction

With BFR, exercises will be performed at 30% one-rep max with the BFR cuff placed around the proximal thigh and inflated to 80% of limb occlusion pressure (avg: 150 mmHg).

OTHERPhysical therapy

Physical therapy consists of two or three 90-minute sessions per week for 6 weeks and a minimum of 18 visits required for study inclusion.
