ABSTRACT

Background: The Anterior Cruciate Ligament (ACL) is a vital structure within the knee joint, providing stability and facilitating smooth movement. As one of the most commonly injured ligaments, ACL tears can significantly impact an individual’s quality of life, particularly for athletes and individuals who engage in high-demand physical activities. Objectives of the study are to compare the effectiveness of blood flow restrictions protocol versus conventional exercise protocol on increasing muscle strength for post-surgery rehabilitation of ACL injury.

Methodology: Two groups Pre and Post-test Quadi-Experimental study design.  20 patients with 4th week postoperative rehabilitation ACL reconstruction age between years both males and females were selected. Group A received Blood Flow Restriction Exercise Protocol whereas Group B received Conventional Exercise Protocol. Outcome Measure: Numerical Pain Rating scale and Manual Muscle Testing were measured used by Interventions. Pre-test and post-test scores were compared, and results were tabulated.

Result: Both groups showed significant improvement in muscle strength and reduce pain. The group A showed statistically significant improvement in muscle strength and reduced pain when compared to Group B (p<0.0001).

Conclusion: The study demonstrated that the BFR Exercise Protocol led to an increase in muscle strength, a reduction in pain, and improved knee flexion in patients undergoing ACL postoperative rehabilitation. Thus, it was concluded that the BFR Exercise Protocol is an effective treatment for ACL rehabilitation than conventional exercise protocol.

Keywords: ACL postoperative rehabilitation, Blood Flow Restrictions Protocol, Conventional Exercise Protocol, Numerical Pain Rating scale, Manual Muscle Testing.
