Osteoarthritis (OA)


Other: Placebo
Device: GID SVF-2

Study type


Funder types




Details and patient eligibility


This is a pivotal study. The study will examine the safety and efficacy of autologous adipose-derived stromal vascular fraction (SVF) cells processed with the GID SVF-2 device for pain, function and stiffness in the knees of osteoarthritic subjects.

Full description

Osteoarthritis is the main form of arthritis and affects over 20 million people in the United States. In the knee it can cause severe pain, reduced functionality and increased stiffness thus, a treatment that would reduce pain, increase function and reduce stiffness would be of benefit to many people. This study will collect and disassociate adipose tissue and inject the stromal vascular fraction into the knee of the same patient. The study is controlled, randomized and double-blinded with 2 SVF treatments (high and low dose) and a placebo control.


39 patients




40 to 75 years old


Accepts Healthy Volunteers
