Brief summary
In this study, researchers want to determine the safety of MSCs that a patient can tolerate without causing side effects. Moreover researchers will also be looking at the function of the knee over time, which may give them some insight on the usefulness of MSCs as a treatment option.
Detailed description
Osteoarthritis (OA) is one of the most common forms of arthritis. It is a lasting condition in which the material that cushions the joints, called cartilage, breaks down. This causes the bones to rub against each other, causing inflammation, stiffness, pain and loss of joint movement. Currently, there are few effective treatments available for patients suffering from OA. Mesenchymal stem cells (MSCs) are cells that have the ability to self-regenerate, which means they have the ability to make copies of themselves and to turn into other kinds of cells (e.g. cartilage cells). Stem cell science shows much promise for the future treatment of osteoarthritis, but much of the research is still in the early stages. In this study, researchers want to determine the safety of MSCs that a patient can tolerate without causing side effects. Moreover researchers will also be looking at the function of the knee over time, which may give them some insight on the usefulness of MSCs as a treatment option.

Patients with a history of septic arthritis in the affected joint 5. Patients with a history of a prior intra-articular knee fracture 6. Severe bleeding diathesis 7. Contraindication to bone marrow aspiration and/or biopsy 8. Active infection 9. Bone marrow failure 10. Cytopenia 11. Patients who have previously received radiotherapy to the pelvis 12. Patients who have been on chemotherapy from within a year of the date of informed 13. Patients with positive serological test for (HIV, HTLV1&2, Hep A, B, C, syphilis) 14. Pregnancy or risk of pregnancy (this includes participants that are not willing to practice active contraception for the duration of the study) 15. Patients with unforeseen conditions that are deemed unsafe or inappropriate for the study (e.g. patients who are claustrophobic and cannot undergo an MRI) as per the discretion of the principal investigator
