Study summary

To evaluate the effectiveness and safety of JETKNEE Synovial Fluid Supplement for alleviating pain of knee osteoarthritis (OA).

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. The pain score of Visual Analog Scale (VAS) of target knee at 6 months post-treatment.

    The pain score of Visual Analog Scale (VAS) of target knee at 6 months post-treatment. Based on the patient described pain intensity as 0 to 10 score, a higher score indicates greater pain intensity.

    Time frame: 6 months post-treatment

Secondary outcomes

  1. The pain score of VAS of target knee at baseline, 2 weeks, 1 month, and 3 months post-treatment

    The pain score of VAS of target knee at baseline, 2 weeks, 1 month, and 3 months post-treatment. Based on the patient described pain intensity as 0 to 10 score, a higher score indicates greater pain intensity.

    Time frame: baseline, 2 weeks, 1 month, and 3 months post-treatment

  2. The average score of Western Ontario and McMaster Universities (WOMAC) in pain section of the target knee at baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment

    The average score of Western Ontario and McMaster Universities (WOMAC) in pain section of the target knee at baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment The WOMAC measures five items for pain (score range 0-20).Higher scores indicate worse pain, stiffness, and functional limitations.

    Time frame: baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment

  3. The average score of WOMAC in stiffness section of target knee at baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment

    The average score of WOMAC in stiffness section of target knee at baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment. The WOMAC measures two for stiffness (score range 0-8).Higher scores indicate worse pain, stiffness, and functional limitations.

    Time frame: baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment

  4. The average score of WOMAC in function section of target knee at baseline and 2 weeks, 1 month, 3 months and 6 months post-treatment
