Résumé :	Platelet-rich plasma injections have been proposed as an option for Conservative management of knee Osteoarthritis to provide symptomatic relief and also to delay the need for surgical intervention. Although almost all the current literatures provide some evidence on the benefits of this technique compared with Visco- supplementation, no studies have been performed to compare their Clinical outcomes. The purpose is to compare the Clinical outcomes provided by intra- articular injection of either Platelet rich plasma or Hyaluronic acid to treat knee Osteoarthritis. Study Design: Randomized Controlled Trial 200 Patients with a history of Symptomatic knee Osteo- arthritis (Kellgren-Lawrence grade 2 or 3) were randomized to undergo 3 blinded intra-articular in- jections of either Platelet rich plasma or Hyaluronic acid. The Interval between successive injections was 2 weeks. Patients were evaluated prospectively before the injection and then at 2, 6, 12, 24, 30 and 36 months. Evaluation was based on International Knee Documentation Committee (IKDC), Visual analog scale, VOMAC Score and the re- injection rate; 189 patients reached the final evaluation. Both platelet rich plasma and Hyaluronic acid were effective in improving knee Symptoms and functional status over time and remained stable over time up to 18 months Post-injection (No re-injection has been performed to any patient incorporated in this study during the first 18 months). The performed re-injections have been significantly lower in the PRP group. Both platelet rich plasma and Hyaluronic acid were effective in improving knee Symptoms and functional status over time and remained stable over time up to 18 months Post-injection. The rate of the required re-injections has been significantly lower in platelet rich plasma group. platelet rich plasma provide longer duration of symptomatic relief, longer duration of functional status improvement and lesser number of needed re-injections than Hyaluronic acid when the patients have been followed through 36 months.
