case_images: MRI T1-weighted images of the ankle in coronal (A) and sagittal view (B) at the time of the first evaluation.. MRI exhibiting extensive bone infarctions of the talar head and body, occupying almost all of its volume. Focal chondropathy of the talus and distal tibial could also be identified.

case_images: Focal chondropathy in the talus and distal tibial could also be identified (Figure 1).
case_images: Isolation and preparation of adipose-derived stromal vascular fraction (SVF).. A. Harvesting of adipose tissue performed via subcutaneous liposuction from the lower abdominal area. B. Microfat processing for the isolation of SVF. Mechanical dissociation of adipocytes during microfat processing facilitates the extraction and concentration of the regenerative cells within the SVF, allowing its collection as a pellet.

case_images: In the operating room, approximately 30 mL of adipose tissue was harvested via subcutaneous liposuction from the lower abdominal area under sterile conditions (Figure 2A). The SVF was isolated by additional processing of the microfat, with further mechanical dissociation of the adipocytes whereby the regenerative cells within the SVF could be collected as a pellet (Figure 2B).
case_images: MRI T1-weighted images of the ankle in coronal (A) and sagittal view (B) at the 18-month follow-up.. Comparison MRI revealing a relatively stable avascular necrosis with a small insufficiency fracture of the lateral trochlea but no evidence of collapse.

case_images: At this follow-up, a comparison MRI revealed a relatively stable AVN with a small insufficiency fracture of the lateral trochlea but no evidence of collapse (Figure 3).
