Poster Abstract

Post operative recovery from Anterior Cruciate Ligament Reconstruction (ACLR) includes extensive rehabilitation of 6-9 months with return to sport/activity at 12 months

Rehabilitation is initiated shortly following surgery to limit quadriceps and hamstring atrophy, maximizing long term tibiofemoral joint stability and functional outcomes

The best way to achieve improved muscle strength and prevent atrophy is progressive overload training, however, these activities cannot be performed post operatively without risk to the reconstructed knee

Blood Flow Restriction Training (BFR) involves impairing the blood supply for short periods through the application of an air-filled bladder or cuff to restrict the venous drainage of the region of choice

BFR allows the surgically repaired limb to be safely stressed after ACLR without added reinjury potential of progressive overload training

BFR achieves this elevated stress via systemic hormone production, cell swelling, production of reactive oxygen species, and increased fast twitch fiber recruitment along with stimulation of anabolic and anti-catabolic cell signaling pathways, particularly the mTOR (mechanistic target of rapamycin) protein kinase pathway

There is inconsistency of methods, outcome measures and results in literature comparing the outcomes of BFR vs Traditional Post Operative Rehabilitation (TPR)

Is Blood Flow Restriction Training Superior for the Limitation of Hamstring and Quadriceps Atrophy After Anterior Cruciate Ligament Reconstruction? A Review of Randomized Controlled Trials

Post operative recovery from Anterior Cruciate Ligament Reconstruction (ACLR) includes extensive rehabilitation of 6-9 months with return to sport/activity at 12 months
