BFRT in Adolescents After ACL Reconstruction

This is an interventional study that will examine effects of blood flow restriction training (BFRT) in adolescents aged 12-18 after anterior cruciate ligament reconstruction surgery (ACLR). The study aims to identify the effect of BFRT on quadriceps muscle strength and the patient's quality of life, and the overall tolerability of BFRT will be examined. Eight physical therapists at four sports medicine physical therapy (PT) sites will oversee all post-operative PT sessions. Subjects allocated to the BFR group will undergo BFRT, while control group will undergo standard-of-care ACLR rehabilitation, 2 days per week for 16 weeks. Measurements of strength, quality of life, and overall function will be completed at regular intervals.
