简要总结
Stromal vascular fraction of cells (SVF) will be extracted from lipoaspirate by enzymatic digestion. SVF will be administered in a single dose intraarticularly. All patients will receive cell therapy.This is a single arm study with no control.
详细描述
Patients with knee osteoarthritis will be subjected to abdominal liposuction under local anaesthesia. Harvested adipose tissue will be processed according to patent pending technology based on enzymatic digestion, washing and concentration of cell pellet in 5 ml of Hartmann's solution. Isolated SVF will be administered in a single dose into anterior part of knee joint cavity.
