Abstract

ACL injuries are common in athletes and active individuals, with a significant impact on knee stability, function and strength. The ACL is crucial in activities involving jumping, cutting, and pivoting which places the ligament under increased stress, increasing the risk of rupture. ACLR surgery is often necessary, especially in younger, active individuals, to restore knee stability, function and strength. The purpose of this literature review is to explore the effectiveness of BFR-RT as an alternative or adjuvant to traditional rehabilitation techniques following ACLR surgery. The electronic databases PubMed and Embase were searched, and the seven studies included for this review were randomized controlled trials published within the last five years. Current research findings suggest BFR-RT provides equal or superior benefits in quadriceps strength development, improved knee joint function, and decreased pain during the rehabilitation process. BFR-RT may also accelerate recovery and reduce the RTS time or physical activity while reducing the strain on healing tissues. Future research is essential to eliminate the gaps in current studies, such as the relevance of graft type, effects on adolescence and older adults, effects of BFR-RT prior to ACLR surgery and activity level prior to injury seem most important currently.
