NCT03794570

Brief Summary

This study is a prospective, double-blinded, randomized control trial examining the effect of blood flow restriction (BFR) therapy on reducing post-operative quadriceps atrophy in patients undergoing anterior cruciate ligament reconstruction (ACLR). Following ACLR, patients will undergo a rehabilitation protocol either w/ BFR therapy or sham BFR therapy.

Patients in this group will have BFR tourniquet applied but inflated to only minimal pressure.

Device: Sham blood flow restriction therapy - with Delfi Personalized Tourniquet System

Blood Flow Restriction (BFR) Therapy

EXPERIMENTAL

Patients in this group will have BFR tourniquet applied and inflated to 80% limb occlusion pressure

Device: Blood flow restriction therapy - with Delfi Personalized Tourniquet System

Interventions

Physical therapy performed with Blood flow restriction therapy tourniquet inflated to 80% limb occlusion pressure

Blood Flow Restriction (BFR) Therapy

Physical therapy performed with Blood flow restriction therapy tourniquet inflated to only minimal pressure
