Overview

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

Inclusion Criteria:

  • Anterior cruciate ligament (ACL) reconstruction with concomitant meniscus or cartilage restoration procedures
  • Adherence to modified weight bearing status before initiation of PT
  • Expected participation in recreational or competitive sports after release to full activities

Exclusion Criteria:

  • Unable to attend (or participate in) physical therapy
  • Pregnancy
  • Malignancy
  • Fracture
  • Peripheral vascular disease
  • History of deep vein thrombosis (DVT)

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
