Abstract:Objective To explore the clinical characteristics of knee osteoarthritis (KOA) complicated with metabolic syndrome (MS). Methods A total of 390 patients with KOA in Xuanwu hospital, Capital Medical University from January 2015 to September 2017 were enrolled in this survey. The subjects were divided into MS group (151 cases) in which patients had MS and non-MS group (239 cases) in which patients did not have MS. Clinical data were recorded. Results Gender ratio between two groups was statistically significant (P < 0.05). BMI, waist circumference, diastolic blood pressure and systolic blood pressure in MS group were higher than those in non- MS group (P < 0.05). The prevalence of hypertension, diabetes, coronary heart disease and cerebrovascular disease in MS group were increased compared with non-MS group (P < 0.05). The VAS score, WOMAC score and K-L grading score were enhanced in MS group than those in the non-MS group (P < 0.05). The levels of GLU, TG, TCH, LDL-C and ESR of the MS group were significantly upregulated when compared with those in non-MS group (P < 0.05). Conclusion Patients with KOA combined with MS experience severe metabolic disorder and joint disease, who should receive effecfive inferventions.
