Effectiveness of Blood Flow Restriction in Postoperative Rehabilitation for Anterior Cruciate Ligament Injuries. A Pilot Study.

Blood Flow Restriction (BFR) therapy in this study involves the application of a pneumatic cuff around the proximal thigh to restrict arterial blood flow during specific rehabilitation exercises. The cuff will be inflated to achieve 70-80% of arterial occlusion, while participants perform low-intensity resistance exercises at 15-20% of their one-repetition maximum (1RM). BFR therapy will be used during Phase 2 of rehabilitation (weeks 2-12) alongside a standardized rehabilitation protocol. The intervention will be closely monitored by trained Physical Therapists to ensure safety and efficacy, with pressure adjustments made in real-time based on the participant's exercise performance. This intervention distinguishes itself by its use of BFR, a technique that is not part of conventional ACL rehabilitation

The Standard Rehabilitation (RHB) intervention in this study consists of a structured, evidence-based protocol designed to optimize recovery after anterior cruciate ligament (ACL) reconstruction. This rehabilitation protocol is implemented across four phases. The rehabilitation will be supervised by experienced Physical Therapists, and participants will be given a tailored home exercise program to complement the supervised sessions. The intervention aims to optimize recovery, restore function, and reduce the risk of re-injury.
