Metabolic Syndrome and Degenerate Meniscus Tears

First Affilated Hospital of Jinzhou Medical University

The aim is to determine the outcomes of calorie-restricted diet and exercise intervention; libitum diet and waiting list control; early arthroscopic partial meniscectomy(APM) or delayed APM effect on MetS patients with Degenerate menisucus lesions.

The investigators recruited 180 patients with Metabolic Syndrome and knee symptoms with degenerate meniscus lesions by MRI from orthopaedics department from June 2017 to March 2020 at First Affiliated Hospital of Jinzhou Medical University. Participants were diagnosed with MetS and degenerate meniscus tear with a mild or no osteoarthritis KL<2 verified by X ray. Participants were randomly dividied into calorie-restricted diet and exercise intervention group; libitum diet and waiting list control group; early APM (syndrome within 3-6 months) group or a delayed APM(syndrome more than 6 months) group as a computer sequenced number. The primary outcome was the change in metabolic syndrome components and knee function score of WOMAC, KOOS,WOMET,IKDC were determined by two fixed orthopadic surgeons who were blinded to the intervention.
