Brief Summary

This is a pivotal study to evaluate the efficacy and safety of a single injection of autologous adipose-derived SVF produced using the GID SVF-2 device system for treatment of pain with concomitant improvement in function associated with osteoarthritis of the knee joint.

Detailed Description

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).

Conditions

Osteoarthritis, Knee

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

Placebo

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