Brief Summary

The anterior cruciate ligament (ACL) is the main stabilizer of the knee joint, as it controls anteroposterior and rotatory knee laxity. The number of ACL injuries has increased in the past three decades because more and more people participate in recreational and competitive sporting activities. Injury to the ACL often leads to functional instability, damage to the meniscus and articular cartilage, and an increased risk for osteoarthritis (OA). Emphasizes the fact that ACL has limited healing potential 'The gold standard' treatment is ACL reconstruction, with over 200,000 reconstruction surgeries performed annually in the United States. However, despite the success of surgery in restoring functional stability, it has been found so far in several studies that the prevalence of moderate to severe arthritis in long-term radiographic follow-up is more than 50% after ACL reconstruction within 5 to 15 years or sooner. ACL-injured knees had at least 3 times higher risk of arthritis than uninjured contralateral knees. Early osteoarthritis was observed on magnetic resonance imaging (MRI) up to 11 years following ACL injury after operative and nonoperative management. Because ACL injuries predominantly occur in individuals between the ages of 15 and 25 years, symptoms of OA most often affect patients during their most productive years. This is worrisome because most patients who sustain ACL tears are free of the risk of other factors for developing OA.Consequently, posttraumatic OA after ACL reconstruction ultimately translates into a large economic effect on the healthcare system owing to the young age of this population. Platelet-rich plasma is an autologous solution of highly concentrated platelets dispersed in a small capacity of plasma. Enthusiasm for the therapeutic potential of platelets is based on its rich omplement of anabolic growth factors and anti-inflammatory cytokines in the platelets, which induce cellular proliferation, migration, differentiation, angiogenesis, and extracellular matrix synthesis. In addition, the functional mechanisms of PRP in OA treatment have been explained by its effect on modulating critical pro-inflammatory mediators and catabolic enzymes, as well as maintaining joint homeostasis. The reasons for this early incidence of post-traumatic OA remain unclear, but the underlying mechanisms have been speculated to involve some combination of cartilage damage at the time of injury, and posttraumatic molecular changes in the joint, including immune reactions or persistent secondary inflammation. We hypothesized that PRP injection after ACL reconstruction could prevent cartilage damage, act anti-inflammatory, and provide better clinical and radiological outcomes seen in MRI.
