To explore the therapeutic effect of sodium hyaluronate combined with glucosamine sulfate in the treatment of knee osteoarthritis.

A total of 90 outpatients and inpatients with knee osteoarthritis who visited the Department of Orthopedics and Traumatology, Daishan County Hospital of Traditional Chinese Medicine from January to June 2020 were selected, and they were divided into sodium hyaluronate group (control group) and sodium hyaluronate combined with glucosamine sulfate group (observation group) by random number table method, with 45 patients in each group. Visual analog scale (VAS) score was used to evaluate the changes of pain in the two groups before treatment, 5 weeks and 6 months after treatment, respectively; at the same time, the total effective rate of 5 weeks and 6 months after treatment was compared between the two groups.

Before treatment, there was no significant difference in VAS scores [(7.4 ± 1.5) vs (7.3 ± 1.7) points] between the two groups (t = 0.24, P = 0.812); at 5 weeks [(5.3 ± 1.1) vs (4.1 ± 1.2) points] and 6 months after treatment [(4.0 ± 0.8) vs (3.2 ± 0.9) points], the VAS scores of the observation group were significantly lower than those of the control group, and the differences were statistically significant (t = 5.54, 5.32, P < 0.001). Compared with the same group before treatment, VAS scores were lower in the two groups at 5 weeks and 6 months after treatment, and the differences were statistically significant (P < 0.05). At 5 weeks after treatment, there was no significant difference in the total effective rates [44.4% (20/45) vs 48.9% (22/45)] between the two groups (χ² = 0.18, P = 0.672); at 6 months after treatment, the total effective rate of the observation group (91.1%, 41/45) was significantly higher than that of the control group (66.7%, 30/45), and the difference was statistically significant (χ² = 8.07, P = 0.004).

Sodium hyaluronate combined with glucosamine sulfate can significantly reduce the pain in patients with knee osteoarthritis, the total effective rate is higher, and is better than the effect of sodium hyaluronate alone.
