Metabolic Syndrome and Degenerative Meniscus Lesions Related Knee Function

Study Overview
=================
Brief Summary
-----------------
Studies have suggested that Obese patients with metabolic syndrome(MetS)were correlated with knee joint degeneration and osteoarthritis. However, no studies demonstrate the relationship between obese patients with metabolic syndrome and degenerate meniscus lesions and its knee function.The aim is to detect the correlation between obese patients with metabolic syndrome and degenerate meniscus injuries.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the Knee injury and Osteoarthritis Outcome Score (KOOS) total | The Knee injury and Osteoarthritis Outcome Score (KOOS) holds five subscales including: Pain (9 items); other Symptoms (7 items); Activities of Daily Living (ADL, 17 items); Sport and Recreation function (Sport/Rec, 5 items); and knee-related Quality of Life (QoL, 4 items). Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems). | up to 12 month | 
| The International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC) score | The International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC) score to determine the meniscus function. The IKDC is a questionnaire that has high reliability and validity for patients with a meniscal tear[36, 37] [38]. The questionnaire contains 18 items (7 items for symptoms, 1 item for sport activity, 9 items for daily activities, and 1 item for current knee function.) The total score is transformed to a value on a scale of 0 to 100, with 100 representing the highest knee function and 0 is the worst. | up to 12 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| KOOS Pain subscale | Pain including 9 items，The minimum value is 0 and maximum values subscale is 100, the scored separately from zero (extreme knee problems) to 100 (no knee problems) | up to 12 month | 
| Symptoms subscale | Symptoms including 7 items,The minimum value is 0 and maximum values subscale is 100. Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems) | up to 12 month | 
| Activities of Daily Living subscale | Activities of Daily Living including 17 items,The minimum value is 0 and maximum values subscale is100. Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems). | up to 12 month | 
| Sport and Recreation function subscale | Sport and Recreation function including 5 items,The minimum value is 0 and maximum values subscale is 100. Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems). | up to 12 month | 
| knee-related Quality of Life subscale | knee-related Quality of Life including 4 items,The minimum value is 0 and maximum values subscale is 100. Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems). | up to 12 month | 
| KOOS4 | KOOS4, The minimum value is 0 and maximum values subscale is100. KOOS4 defined as the average score for four of the five knee injury and osteoarthritis outcome score (KOOS) validity for patients with meniscal tears and osteoarthritis. | up to 12 month |
