It is a prospective, double blinded, Randomized Controlled Trial study. Data will be prospectively collected of all injectable acellular amniotic membrane derived allograft knee performed at our institute (1 vs 2 mL).~90 subjects will be enrolled in the study. Subjects will be randomized 1:1:1 in treatment arms.~It compares the dose affect of an amniotic membrane allograft between a 1 mL dose and a 2 mL dose when compared to a placebo of sterile saline in the treatment of osteoarthritis of the knee. This will be offered as a free pain management alternative to patients who meet the inclusion criteria. The results will be determined by validated patient-reported outcome tools (KOOS, VAS, and WOMAC questionnaires) and physical examinations taken before the injection, one month after the injection, three months after the injection, six months after the injection, and one year after the injection. There will be a phone call 24 hours after the injection for every patient participating in the study regarding any potential adverse events.
The purpose of this study is to determine the dose effect of a single injectable acellular amniotic membrane derived allograft for the treatment of knee osteoarthritis and to confirm whether the use of 2 mL of the same amniotic injection offers a statistically significant advantage over the 1 mL injection when compared to a placebo.
