The study will also assess safety of A2MRP intraarticular injection in patients with symptomatic knee OA. Patients with symptomatic mild to moderate knee OA (KL 2-3) will be candidates for this study. Baseline data will include physical examination of the knee, clinical assessment of knee pain and function using validated patient reported outcome measures (PROMs), and radiologic exam of the knee will be obtained. All injections will be performed using ultrasound guidance and all patients will followed-up at week 1 week post-injection for acute adverse events (AEs). Each subject will be clinically followed-up for study endpoints using a predetermined protocol. PROs will be collected during the study period pre-procedure, and at 1, 2, and 6 weeks, 3-, 6-, 9- and 12-months post-procedure (Specific PRO's and timepoints noted in sections 6.2-6.7). Subjects will also be asked questions regarding satisfaction with the treatment and whether they would recommend the treatment"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
