Osteoarthritis (OA) is the most common form of chronic joint disease. A treatment option for patients diagnosed with knee osteoarthritis is intra-articular hyaluronic acid therapy. In this prospective, randomized controlled, single blind, interventional study, a total of 90 patients with stage 2-3 knee osteoarthritis according to the kellgren lawrence classification who meet the eligibility criteria will be enrolled in the study. Eligible participants will be randomly assigned to one of the three groups using computer-generated random numbers. In the first group, 2 ml linearly linked 20 mg 1.0% hyaluronic acid injection in 5 sessions, in the second group 2 ml linearly linked 32 mg 1.6% hyaluronic acid injection in 3 sessions and in the third group 2.4 ml linearly linked 48 mg 2.0% hyaluronic acid injection in a single sessions will be applied. Participants are going to evaluate before injection, and at the 1-month follow-up and 6-month follow-up using the visual analog scale (VAS) scores for pain during activity, at rest, and at night, with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) change in pain, stiffness and physical function score, the change in the Timed Up and Go Test (TUG) time and the change in the patient's daily activities with the numerical global patient assessment scale.
