Before treatment, no significant differences were found in the levels of inflammatory factors VEGF, TNF-α, IL-1β, IL-6, hs-CRP and MMP-13 in the joint fluid between the two groups (P>0.05). After treatment, the levels of the above inflammatory factors were significantly lower in observation group than those in control group (P<0.05), and they declined in both groups compared with those before treatment (P<0.05) (Levels of inflammatory factorsP<0.05 P<0.05
