Overview
Brief Summary
This is a multi-center, randomized, double-blind clinical investigation to compare the effectiveness of intra-articular polyacrylamide hydrogel (PAAG-OA) and a hyaluronic acid, Synvisc-One to induce symptomatic benefit in subjects with knee osteoarthritis.
Detailed Description
The trial is designed as a multi-center, randomised, controlled, double-blind, and parallel-group trial spanning over 12 months with outcome assessments at baseline, 1, 3, 6 and 12 months incl. follow-up period between 2-5 years. Primary endpoint at 6 months. The trial is designed to compare effectiveness and safety of injection of PAAG-OA and Synvisc-One® in participants with knee OA.
