The medical device is a bioabsorbable, extensible, crosslinked, 2% hyaluronic acid gel using micro-organism fermentation sourced hyaluronic acid as a major component and add mannitol is added which can inhibit the degradation of hyaluronate acid by free radicals to prolong the therapeutic effect. The medical device is injected into the articular cavity to protect joint tissue, increase joint lubricity, inhibit degradation of cartilage and promote the metabolism of cartilage by infiltrating degenerated cartilage. In addition, the medical device can penetrate the synovial tissue to inhibit inflammation and degradation. It also inhibits pain mediators in the synovium to achieve the pain inhibition. This study is to evaluate the effectiveness and safety of JETKNEE Synovial Fluid Supplement for alleviating pain of knee OA 6 months after single injection.
