Presence of retained rods or screws or insertion or joint replacement in the joint to be injected 5. History of autoimmune diseases including lupus and rheumatoid arthritis 6. Prior arthroscopic or open surgery of the index joint within 6 months prior to screening 7. Planned arthroscopic or open surgery of the index joint during study period 8. Intra-articular injections in the index joint within 3 months prior to screening for corticosteroids or dextrose injections, and within 6 months prior to screening for hyaluronic acid or platelet-rich plasma (PRP) injections 9. Use of systemic immunosuppressives, immunomodulators or chemotherapeutic agents within 3 months prior to baseline visit 10. Know hypersensitivity to lidocaine, epinephrine or heparin 11. History of coagulopathy 12. Fever (forehead temperature above 38.0 centigrade) at baseline visit 13. Subjects with cutaneous infection at the lipoaspirate or bone marrow aspirate site and/or in the area of the injection at baseline visit 14. Subjects with hemoglobin less than 10 g/L 15. Subjects with platelet count less than 155x109/L 16. Subjects participating in a study of an experimental drug or medical device within 30 days of study entry 17.
