Resumen del estudio

One hundred and eighteen patients with symptomatic knee osteoarthritis were randomized to receive either intra-articular micro-fragmented adipose tissue injections (MF-AT; n=59) or platelet-rich plasma injections (PRP; n=59). The primary outcome of this trial was the change in International Knee Documentation Committee (IKDC) scores and pain subscale of the Knee Osteoarthritis Outcome Score (KOOS) from baseline to 6 months. Other outcomes such as KOOS subscales for functional improvement, EuroQol visual analog scale (EQ-VAS), EuroQol 5 Dimensions (EQ-5D), and Visual Analog Scale (VAS) for pain at 3, 6, 12, and 24 months. MRI findings using the Whole-Organ Magnetic Resonance Imaging (WORMS) score was also assessed. Statistically significant improvements in all clinical scores were apparent in the MF-AT group, except for EQ-VAS scores. IKDC and KOOS scores improved from baseline to 6 months.
