Blood flow restriction training after knee arthroscopy to help quadriceps

Official title: Effects of Blood Flow Restriction Training on Lower Limb Muscle Strength and Atrophy in Patients With Knee Arthropathy: A Randomized Controlled Trial

Run by The Affiliated Hospital Of Southwest Medical University · NCT07837154 · Data updated 2026-11-12

This study tests whether wearing a device that restricts blood flow while doing rehab after knee arthroscopy helps the quadriceps regain strength and improves function compared with a sham intervention.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–60 who have undergone knee arthroscopy and can commit to follow-up assessments and rehabilitation.

Probably not a fit

Individuals with neurological disorders, vascular issues, or contraindications to BFRT may not benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants who have knee arthroscopy will follow a standard rehab program for 2 weeks, then receive either constant-pressure blood flow restriction training or a sham BFRT for 12 weeks. The goal is to see if CP-BFRT changes neurophysiological responses related to Arthrogenic Muscle Inhibition and improves physical function. The study uses 60–80% occlusion during BFRT and compares outcomes to a placebo-like sham intervention. Safety will be monitored, and all participants provide informed consent with follow-up assessments planned.

Why it matters

Potential benefit: If successful, CP-BFRT could enhance quadriceps activation and knee function after knee surgery.

How similar studies have gone: Previous work suggests BFRT can influence neuromuscular responses, but results on AMI after knee surgery are still evolving and evidence is ongoing.
