Not Applicable

Completed

• Conditions: Hyaluronic Acid; Knee Osteoarthritis
• Interventions: Device: JETKNEE Synovial Fluid Supplement; Device: Normal saline

• Registration Number: NCT05201040
• Lead Sponsor: SciVision Biotech Inc.

Brief Summary

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

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.

Primary Outcome Measures

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

Secondary Outcome Measures
