Clinical Trial Summary

This study evaluates the safety and efficacy of investigational products in the treatment of knee Osteoarthritis. Half of participants will receive medical chitosan, while the other half will receive sodium hyaluronate.

Description:

Medical chitosan and sodium hyaluronate each form the reticular layer to cover the joint surface, alleviate the joint friction and pain. For medical chitosan, its half-life is longer than sodium hyaluronate, so the interval time of intra-articular injection is longer.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analogue Scale for knee pain	The investigator and the subject both evaluate the pain intensity per VAS before injection. VAS ranges from o to 10, 0=no pain, 10=pain as bad as can be.	six weeks of the initial injection	No
Secondary	WOMAC for knee pain	WOMAC includes 3 items: pain, stiff and physiological function. 0=no, 4=as bad as can be.	six weeks of the initial injection	No
