Outcome of Hyaluronic Acid for Knee Osteoarthritis

Osteoarthritis(OA) is the most common chronic condition of the knee joints that takes place when the cartilage or a low friction surface between joints breaks down which leads to pain, stiffness and swelling. Total 56 patients with osteoarthritis of knee, randomized to receive intra articular hyaluronic acid injection and were followed up for 3 months. Patients were evaluated with the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC), Knee injury and Osteoarthritis Outcome Score (KOOS) and the visual analog scale. This study was done for the evaluation of the therapeutic effect of intra articular injection of hyaluronic acid (HA) in knee osteoarthritis. Patients mean age were57 ±9 years. WOMAC score shows that stiffness did not improved after intervention, (P> 0.05). KOOS score shows that after intervention, symptoms were improved (P< 0.05).
