This is a prospective, randomized, placebo controlled, parallel groups, double blind, multi-center, interventional study of subjects with osteoarthritis of the knee. Subjects will be randomized to receive an injection of LR (placebo) or SVF derived from their own adipose tissue (experimental).

Arms

Placebo Comparator: Placebo

Subjects will receive an injection of Lactated Ringers in their index knee

Experimental: Stromal Vascular Fraction (SVF)

Subjects will receive an injection of Stromal Vascular Fraction in their index knee

Interventions

Device: - GID SVF-2 Device System

The GID SVF-2 Device System is used for harvesting, filtering, separating and concentrating autologous stromal vascular fraction from adipose tissue.
