Efficacy of stromal vascular fraction for knee osteoarthritis: A prospective, single-centre, non-randomized study with 2 years follow-up

Figure 4 A representational case from group B. A: Pre-procedural radiograph of bilateral knees (anteroposterior (AP) view on standing position) showing decreased medial joint line in bilateral knees suggestive of Kellgren Lawrence grade II knee osteoarthritis (OA); B: Pre-procedural T2W magnetic resonance imaging (MRI) (coronal section) showing hyperintensity with thinned out cartilage along the medial femoral condyle suggestive of OA knee; C: 2-years follow-up radiograph of bilateral knees (AP view on standing position) showing no improvement in the thickness of medial joint line in bilateral knees; D: 2-years follow-up T2W MRI (coronal image) showing no cartilaginous thickness indicating response to corticosteroids therapy.
