Osteoarthritis, Knee
Conditions
Brief summary
The purpose of this study is to prove the non-inferiority of the intra-articular injection of hyaluronic acid (Sinovial®) in the symptomatic treatment of knee OA in comparison to Synvisc®.
Interventions
2 mL 0.8% sodium hyaluronate (16 mg) solution. 3 intra-articular injections once-a-week.
2 mL 0.8% Hylan G-F 20 (16 mg) solution. 3 intra-articular injections once-a-week.
