Abstract：Objective:To understand the distribution of normal knee cartilage andfemoralcondyle cartilage thickness of the weight bearing regions, to provide a basis for early diagnosis and dynamic observation for the knee joint disease. Methods:50 male and 50 female, a total of 100 adult volunteers were involved, ranging from 20 to 30 years old, with a mean age of 25.3 years. All the knees were scanned by magnetic resonance imaging (MRI). Knee cartilage thickness of medial tibia platform, lateral tibia platform, patellar, femoral trochlea, medial and lateral femoral condyle in sagittal windows were measured in the software MIMICS. The maximum cartilage thickness of the selected area of normal weight bearing region were measured and compared. The three-dimensional morphological characteristics of the knee cartilage reconstructed was observed by MRI.Results:The maximum thickness of the knee joint cartilage on each regions were as follows:Tibia lateral platform:3.19mm,tibial medial platform:3.07mm,femoral lateral condyle:2.93mm, femoral medial condyle:3.19mm, femoral trochlea cartilage:3.57mm, patellar cartilage:3.75mm.There were no statistical differences between men and women for cartilage thickness(P ＞ 0.05),but significantly statistical differences between weight bearing regions and non- weight bearing regions( P ＜ 0.05).Conclusions:The thickness of the normal adult knee joint cartilage is various in different regions, thickness of the weight bearing regions were significantly greater than the non-weight bearing regions in femoral condyle.Thickness of the knee joint cartilage can be accurately measured and the three-dimensional morphology of knee joint cartilage can be easily reconstructed based on MRI.
