On the articulating surfaces, I have an sliding elastic contact interface with a penalty of 1000, and frictional coefficient of 0.02. Cartilage can be generally classified into the following main types: hyaline cartilage. Both the femoral and tibial components are treated this way. Cartilage or cartilaginous tissue is a resilient and type of connective tissue of mesodermal origin that forms an integral part within the musculoskeletal system and as a structural component in other organs.

The cartilage is modeled as neo-hookean with a density of 1100kg/m3, 3.3MPa stiffness, and 0.4 poissons. ![]() The cookie is used to store the user consent for the cookies in the category "Other.

The 2022 Medicare National Payment amount for 73701 – CT lower extremity w/ dye: $179.26.The 2022 Medicare National Payment amount for 73725 – MR Ang lwr ext w/ or w/o dye: $365.10.A weight bearing CT arthrogram study is less expensive than MRI for patients and payers.Weight bearing CT arthrogram can be obtained in multiple knee flexion angles, while an MRI knee coil may permit imaging only with the knee in extension.Ability to bear weight bilaterally in a functional position is important for accurate assessment of meniscal position, meniscal pathology under physiological loads, and assessment of cartilage thickness when loaded.Magnitude of muscle and external forces acting about the knee are better recreated during actual standing. Improved and artifact-free 3-D visualization of the cartilage canals was demonstrated by QSM processing of the data, especially by utilizing susceptibility data as an enhancing mask.Visualizing pathology that is not detected in unloaded positions is now possible.3D measurements of the meniscal position and morphology while standing are more accurate.Potential advantages over non-weight bearing MRI/MRA include: With standing CT, specialists can obtain 3D imaging of the knees while they are under physiological load, similar to fixed-flexed or semi-flexed radiograph protocols. ![]() Weight Bearing CT arthrogram may be useful for assessment of menisci as well as tibiofemoral and patellofemoral cartilage in a functional stance. However, absence of weight bearing limits evaluation of these structures in a functional position. MRI is the current standard of care for non-invasive visualization of the cartilage and menisci. ![]()
