This study will be an open-label trial to determine the functional effects of bilateral IA
injections of Zilretta into knee joints of 70 subjects with bilateral KL grade 2-4
symptomatic knee osteoarthritis (OA). Measurement and evaluation of outcomes at baseline, 6,
12 and 24 weeks will allow assessment of short and long-term effects, consistent with
