Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Use of electrotherapy or acupuncture for OA, unless there is a stable regimen for at least 4 weeks before baseline assessment. 18. Taking anti-rheumatic disease medication (including methotrexate or other antimetabolites) within 3 months prior to study enrollment. 19. On chronic, immunosuppressive transplant therapy or having a chronic, immunosuppressive state, including use of systemic steroids/corticosteroids. 20.

Additional Details

Interventions to alter the natural course of osteoarthritis (OA) in the knee are elusive and joint replacement remains the definitive management for refractory, end-stage disease. The Mayo Clinic has a large, ongoing experience using autologous adipose derived mesenchymal stromal cells (AMSCs) for the treatment of a variety of other diseases under INDs. Thus far, the treatments have been well tolerated. These data along with the investigators' pre-clinical animal studies and published experiences using related approaches lead the investigators to believe that this approach provides a reasonable safety profile to treat patients with refractory painful knee OA. The purpose of the current study is to investigate the safety and feasibility of single and multiple injections of autologous, culture expanded AMSCs in subjects with painful, refractory knee OA. Subjects with unilaterally symptomatic mild to severe knee OA will be enrolled based on satisfaction of inclusion and exclusion criteria.
