The Effect of Autologous Adipose-Derived Stromal Vascular Fractions on Cartilage Regeneration Was Quantitatively Evaluated Based on the 3D-FS-SPGR Sequence: A Clinical Trial Study

Figure 1

The process of establishing the cartilage model. Different color masks used to distinguish healthy cartilage from cartilage defects by setting the threshold are shown. Illustrating the injury of the whole layer of cartilage and partial cartilage defects (a, b). The cartilage of the knee joint was divided into six regions with different color masks, namely, lateral femoral condyle (LF), femoral intercondylar (T), medial femoral condyle (MF), lateral tibia condyle (LT), medial tibia condyle (MT), and patella (P), and the knee cartilage model was established (c, d). The parameters of the model were measured (e) (for example, in the lateral femoral condyle, the thickness, volume, and surface of cartilage defect were 1.88 mm, 121.12 mm³, and 206.37 mm², respectively. The volume of healthy cartilage was 3374.92 mm³).
