Results The scores of pain, swelling and function of knee joint of the two groups significantly decreased after treatment, and the scores of pain, swelling and function of knee joint of the treatment group in one and two weeks were lower than those of the control group (P<0.05, P<0.01). The levels of synovial fluid IL-6 and TNF-α of the treatment group were lower than those of the control group after two-week treatment (P<0.01); the total effective rate was higher than that of the control group (P<0.05). The recurrence rate of the treatment group was lower than that of the control group after discharged for 3 months (P<0.05). There were no obvious adverse reactions during the treatment period.
