The Effect of Micro Fragmented Adipose Tissue (MFAT) on Knee Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
This is a non-surgical trial comparing the clinical and functional outcomes of patients with osteoarthritis treated with Intra-articular injection of Micro Fragmented Adipose Tissue versus conventional therapy of intra-articular injection of corticosteroid.

Detailed Description
-----------------
This study will be a randomized controlled trial to compare outcomes between intra-articular injection of Micro Fragmented Adipose Tissue and intra-articular injection of corticosteroid in patients with mild to moderate osteoarthritis of the knee. Micro Fragmented Adipose Tissue will be harvested at the subcutaneous tissue by lipoaspiration. Once fat tissue is obtained, it will be processed with minimal manipulation in the clinic room. To be considered for participation in this study, patients must have radiographic evidence of mild to moderate osteoarthritis of medial and/or lateral weight-bearing compartments (Kellgren-Lawrence Grade 2 or 3). In addition, patients must meet several inclusion/exclusion criteria to be randomized and included in this study.
