This clinical trial is for patients who have been diagnosed with Kellgren-Lawrence (K&L) Grade 2 or 3 knee osteoarthritis on radiographic examination. Only subjects who voluntarily agree to participate by filling out the written Informed Consent document will undergo screening for subject selection (inclusion/exclusion) criteria, at which time the severity of OA in each knee will be used to determined which knee will be treated (index knee - i.e., the more severely affected knee), and enroll in this study.
