The objective of this study is to compare the safety and effectiveness of Agilus to a saline injection (control) in the treatment of mild to moderate ankle osteoarthritis. This is a multi-center, randomized, double blind, saline controlled, prospective study with two (2) treatment groups. The active group will receive one injection of Agilus per week for three consecutive weeks for a total of three injections. The control group will receive one injection of normal saline per week for three consecutive weeks for a total of three injections. Follow up visits will occur at 4 weeks, 12 weeks and 26 weeks following the third injection.
