Abstract Background: Anterior cruciate ligament (ACL) injuries are common among physically active individuals, leading to pain, instability, and functional limitations in the knee joint. This case study focuses on the use of Blood Flow Restriction (BFR) therapy as a rehabilitation intervention following ACL reconstruction surgery to improve muscle strength, reduce atrophy, and enhance functional outcomes. Methodology: A single-case study was conducted on a patient who underwent ACL reconstruction surgery and experienced persistent weakness and imbalance post-surgery. The patient received BFR therapy using a static cuff on the upper thigh, combined with specific strengthening exercises over a 6-week period. Outcome measures included pain assessment using the visual analog scale, Lower Extremity Functional Score (LEFS), and muscle strength graded using the Medical Research Council (MRC) scale. Results: Following the 6-week intervention, the patient showed improvements in quadriceps and hamstrings muscle strength, as indicated by increased MMT scores. The LEFS score also significantly increased, reflecting enhanced lower extremity function. However, no changes were reported in the visual analog scale for pain perception. Discussion: The study findings suggest that BFR therapy can effectively improve muscle strength, power, and functional activities in individuals recovering from ACL reconstruction surgery. The hypoxic environment induced by BFR may stimulate anabolic signaling, muscle development, and angiogenesis, contributing to enhanced rehabilitation outcomes. Conclusion: The results of this case study support the effectiveness of BFR therapy in enhancing muscle strength, reducing atrophy, and improving functional outcomes following ACL reconstruction.
