Anterior Cruciate Ligament (ACL) injuries are common in sports and rehabilitation plays a pivotal role in restoring function and preventing future complications. This work explores and compares rehabilitation protocols of different durations designed for ACL injuries. The study reviews the existing literature to analyse the effectiveness of short-term, intermediate-term, and long-term rehabilitation programs. Short-term protocols typically focus on immediate postoperative care, emphasizing pain management, swelling reduction, and early range of motion exercises. Intermediate-term protocols extend beyond the acute phase, incorporating progressive strengthening, neuromuscular control exercises, and functional activities to enhance stability and regain functional capacity. Long-term protocols extend over several months and prioritize advanced functional training, sports-specific drills, and a gradual return to pre-injury activities. The comparative analysis involves assessing the outcomes, complications, and patient-reported satisfaction associated with each duration. Factors such as graft healing, muscle strength restoration, proprioception, and overall functional performance are considered. Additionally, the impact of duration on the risk of reinjury and the successful return to sport is explored. The findings aim to provide clinicians and rehabilitation specialists with insights into tailoring protocols based on the unique needs of patients at different stages of recovery. By understanding the strengths and limitations of protocols with varied durations, healthcare professionals can optimize rehabilitation strategies, improve patient outcomes, and contribute to the evolving landscape of ACL injury management.
