Metabolic Syndrome and Degenerative Meniscus Lesions Related Knee Function

Obese patients with metabolic syndrome(MetS)were correlated with knee joint degeneration and osteoarthritis. However, no studies demonstrate the relationship between patients with metabolic syndrome and degenerate meniscus lesions or knee function. Participants were recruited from First Affiliated Hospital of Jinzhou Medical University. 100 BMI<24 people without Metabolic syndrome volunteers aged between 35-70 years old and 80 Metabolic syndrome patients with BMI>27 were included in the study. Obese patients with MetS were assessed knee function and degenerate meniscus tears verified by magnetic resonance imaging. And patients with a mild or no osteoarthritis with Kellgren and Lawrence grade<2 verified by X ray. We tested the relationship between metabolic syndrome and degenerate meniscus lesions. Obese patients with MetS and volunteers were detected by Mcmurry's test and MRI image to measure degeneration grade of meniscus tears. Number of MetS components were accounted and the knee function KOOS, IKDC score or degenerate meniscus tears were analyzed.
