Study type
Description of intervention(s) / exposure
A single 5mL injection into the knee joint space of cell suspension, which includes autologous adipose derived stem cells and sterile normal saline. On average 50million cells are injected.

Adipose (fat) tissue is removed by lipo-aspiration (this may take up to 80 minutes). The fat is processed on-site to isolate the cells (this process takes up to 2 hours). The suspension of stem cells is injected into the knee joint under ultrasound guidance. (about 20 minutes).
