Treatment of Early Knee Osteoarthritis With Autologous Adipose-derived Mesenchymal Stem Cells

Efficacy and Safety of Autologous Adipose-derived Mesenchymal Stem Cells in the Treatment of Early Knee Osteoarthritis

The purpose of this study is to explore the efficacy and safety of autologous adipose mesenchymal stem cells in the treatment of early knee arthritis. Investigator believes that autologous adipose mesenchymal stem cells can relieve pain, improve knee function, promote knee cartilage regeneration and improve life satisfaction of patients.

Investigators extracted abdominal fat from eight patients, extracted autologous adipose mesenchymal stem cells and injected them into the knee joint of the patients. The data were followed up regularly after operation and compared with those before operation.

• Positive serology for HIV-1 or HIV-2, Hepatitis B (HBsAg, Anti-Hepatitis C virus -Ab), Hepatitis C (Anti-hepatitis C virus -Ab) and syphilis;
• Receive other open surgery related to knee operation within 6 months;
• Participation in another clinical trial;
• Failing to comply with the inclusion criteria, unwilling to comply with the research approach, or incomplete data affecting the curative effect or safety judgment.
