This paper presents the results of the treatment of Kellgren-Lawrence grade I and II knee osteoarthritis using Platelet-Rich Plasma (PRP) added with non-cross-linked hyaluronic acid. Seventy-seven knees were treated with three injections, one every two weeks and the results using the modified Lysholm Scoring Scale were evaluated one and three months after the treatment.
