Efficacy of intra-articular sodium hyaluronate in the treatment of knee osteoarthritis.

| Abstract |
To assess the efficacy of intra-articular hyaluronic acid in patients with knee osteoarthritis, sixty female patients with knee osteoarthritis were randomised to three weekly intra-articular injections of 30 mg sodium hyaluronate (Na HA) with a high molecular weight (1.0 to 2.9 million Da) or 40 mg 6-methylprednisolone acetate (6-MPA). The clinical assessments included pain at rest, at weight-bearing and on walking, Lequesne Index and active range of knee flexion. Assessments were done at baseline, at week 4, and at months 3 and 6. A significant decrease in VAS scores for pain at rest, at weight-bearing and pain on walking, and in Lequesne index was found in both groups at week 4 when compared to baseline and there was no significant differences between the two groups. However, at 3(rd) month improvement in all pain scores and Lequesne index was found in favour of hyaluronic acid. At 6(th), no significant difference was found between the treatment groups. Improvement in pain was accompanied by an increase in joint flexion at week 4 and at month 3 in both groups. Both treatments were well-tolerated. The results showed that both intra-articular hyaluronic acid and 6-MPA treatments provide clinically significant improvement and demonstrated that Na HA has a long-term beneficial effect in patients with knee osteoarthritis.
