Amniotic dehydrated cell and protein concentrate versus corticosteroid in knee osteoarthritis: preliminary findings.

The purpose is to report preliminary data on clinical response to dehydrated cell and protein concentrate (dCPC) versus corticosteroid (CSI). A single-site prospective, randomized controlled single-blinded trial of patients with knee osteoarthritis. : Pain and function were assessed using a visual analog scale (VAS), the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Emory Quality of Life (EQOL) measure at 1, 2, 3, 6, 9 and 12 months. 51 patients were enrolled at the time of analysis (27 dCPC, 24 CSI). Both groups demonstrated improvement on the VAS, KOOS and EQOL. Largest differences were observed at 2 (p = 0.05), 3 (p = 0.012) and 6 months (p < 0.001) with a decrease of 1.66 in VAS at 6 months for dCPC (95% CI: -2.67 to -0.65) and 1.34 (95% CI: -2.37 to -0.3) for CSI. Time-averaged measures showed no difference between groups (p = 0.20). Limited data at 9 and 12 months trended toward improvement in the dCPC group. dCPC products may be used as a treatment for knee osteoarthritis. Larger trials are warranted.
