Background and study aims
Osteoarthritis (OA) is the most common type of arthritis and is a main cause of disability and pain. It occurs when the protective cartilage on the end of bones wears away. The bones then rub against one another, causing stiffness, pain and a reduction in the range of movement. The treatment for OA mostly focuses on helping relieve the pain and control symptoms instead of solving the problem. Recently there have been new ideas and technology in orthopedic surgery (surgery that corrects bones and muscles) that has come up with alternative treatments. Using adipose tissues (fat cells) from a patient could help repair the bones and cartilage if it is injected into the area affected with OA. The new Lipogems® technology is a closed system that is designed to harvest, process and inject adipose tissues back into patients to help repair the area with OA. The aim of this study is to evaluate the outcomes of treating patients with knee osteoarthritis and cartilage lesions with adipose tissue to see if it helped improve the knee’s function and reduce pain.
Who can participate?
Patients aged 40-85 years old with knee osteoarthritis.
What does the study involve?
Participants undergo a physical examination and complete a health questionnaire. They then undergo a surgical procedure using the Lipogems system® which takes fat tissues from the patient's stomach area and then reinjects the fat tissues into the knees. Participants have a blood sample collected during the procedure and as well in the follow up at six and 12 months. They are followed up at three, six and 12 months after procedure to assess the pain level and the function the knee.
What are the possible benefits and risks of participating?
A potential benefit for patients is pain reduction and functional improvement of the affected knee. The main risks are haematoma (swelling) at area where the adipose tissue is taken from and short-term knee pain after the procedure. Participants may feel discomfort during the blood test.

| Scientific title | Application of adipose derived mesenchymal stem cells (Ad-MSC) in treating OSTeoarticular and Cartilage lesions |
| Study acronym | OSCT |
| Study objectives | The aim of this study is to explore trophic, mitogenic, anti-scarring, anti-apoptotic, immunomodulatory, and anti-microbial clinical effects of autologous adipose-derived stromal/stem cells (Ad-MSC) in treating patients with osteoarticular and cartilage lesions. |
| Ethics approval(s) | St. Catherine Hospital Ethic Committee, 18/1/2016, ref: EP 001/2016 |
| Health condition(s) or problem(s) studied | Knee osteoarthritis |
| Intervention | Participants undergo a complete physical examination including X-rays/MRI and biochemical laboratory tests. Participants also complete a specific questionnaire (International Knee Documentation Committee (IKDC)) to assess their health. Participants then undergo a surgical procedure (lipoaspiration). The Lipogems® technology, patented in 2010 (PCT/IB2011/052204), is a completely closed tool to harvest, wash, process, and reinject human (or animal) lipoaspirates. This surgical procedure consists of two steps: the infiltration step, in which adrenaline, in a saline solution, and very diluted lidocaine are injected to induce vasoconstriction as well as local anesthesia is injected to facilitate the subsequent lipoaspiration and the aspiration step, in which a standard liposuction technique is performed. The tissue is taken from the abdominal subcutaneous adipose tissue. They then receive intra-articular injection of final product containing derivate of micronized fatty tissue and intact vascular/stromal architecture with pericytes and mesenchymal stem cells (Ad-MSC) into affected knee (or knees) Participants have plasma blood collection and synovial fluid aspirates of IgG glycom analyses taken during the procedure and 6 and 12 months. Followed up is done at baseline, 3, 6 and 12 months to measure the pain level and the functioning of the knee (or knees). In addition MRI and dGEMRIC MRI imaging are performed at baseline and at 3, 6 and 12 months. |

1. Pain in the knee is measured using the visual analogue scale (VAS) at the baseline, 3, 6 and 12 months |
| Key secondary outcome measure(s) |
1. Matrix synthesis in the cartilage layer (glycosaminoglycan content) delayed gadolinium enhanced MRI (dGEMRIC) imaging technique is applied at the baseline, 3, 6 and 12 months. |
