Quantitative Measurement And Clinical Research Of Meniscus In Knee On MRI Scan

ObjectivesSet up the anatomic database of meniscus in nomal knee joint in Guangdong Province by the accurate measurement of knee in MRI imaging and provide evidence to improve the clinical research and diagnosis of meniscus.MethodsWe select normal knee MRI scan of about690people in Guangdong Province, measure the width and the thickness of medial meniscus and lateral meniscus, and measure the maximum transverse diameter and longitudina diameter of the tibial plateau, and measure the transverse diameter and longitudina diameter of the lateral femoral condyle. Then we get the ratio of the data above by calculate and set up the anatomic database of meniscus.ResultTo establish the anatomic database of meniscus in Guangdong Province and set up the analysis according to the age group; to make a deep analysis of the incidence of radial displacement of meniscus and find out the reason; then we set up an analysis about the incidence of injury in medial and lateral meniscus; then we explore the relationship between meniscal degeneration and change of the femoral condyle and the degeneration of cartilage, and quantify the change of the femoral condyle with curvature.ConelusionWe reveal the relationship of cartilage degeneration, meniscal degeneration and age to a certain extent, and prove that the incidence of radial displacement of meniscus have coefficient relationship with the width and thickness of meniscus by linear regression analysis. Then we reveal the flatting of femoral condyle with age and quantify it with curvature, and confirmed the relationship between degeneration of meniscus and osteoarthritis of knee, and provide some valuable theoretical basis to prevent the degeneration of meniscus and knee at last.
