Treatment of Symptomatic Bilateral Knee Osteoarthritis: Intra-articular Injection of Autologous Microfragmented Adipose Tissue and Hyaluronic Acid vs Intra Articular Injection of Autologous Microfragmented Adipose Tissue

The HYALOFAT study is a randomized controlled double-blind trial with parallel treatment arms and 1:1 allocation. By means of a double-blind randomized controlled trial in patients with symptomatic bilateral OA of the knees, the clinical outcomes of autologous microfragmented adipose tissue injection associated with hyaluronic acid in one knee vs autologous microfragmented adipose tissue injection in the contralateral knee will be evaluated and compared. Each patient will then serve as his or her own control and not be informed of the knee assigned to the treatment group. In addition, it will be the aim of the study to evaluate the safety of the combined treatment by documenting any adverse events.
