Objective To investigated the relationship between plasma sclerostin(SOST)and knee osteoar-thritis(KOA). Methods A total of 95 patients with KOA and 95 healthy people were involved.Plasma sclerostin, CTX-II, AGG1 and AGG2 levels were measured by ELISA. The 95 patients were divided based on Kellgren-Law-rence classification. The correlation between plasma SOST level and KL classification, CTX-II, AGG1 and AGG2 were analyzed.Results Plasma SOST level in KOA was significantly lower than that in control group(P<0.001). SOST level was negatively correlated with KL grade (r =-0.828,P < 0.001),also with CTX-II (r =-0.917,P <0.001),AGG1 (r =-0.658,P < 0.001) and AGG2 (r =-0.583,P < 0.001). Conclusions SOST level in KOA patients is related to the degree of cartilage degeneration. Thus, it helps to monitor the progress and evaluate the severity of the KOA.
