Meta-analysis of blood flow restriction training to improve knee function and muscle strength in patients after anterior cruciate ligament reconstruction

• Blood flow restriction training significantly improves knee muscle strength, muscle mass, and function after ACL reconstruction compared to traditional resistance training. • A training frequency of at least three times per week yields greater gains in knee muscle mass. • Blood flow restriction training is a low-load alternative that aligns with post-surgical rehabilitation needs. • The meta-analysis included 11 randomized controlled trials with 317 patients, providing robust evidence.
