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

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

The purpose of this study is to explore the efficacy and safety of autologous adipose-derived mesenchymal stem cells (AMSCs) plus autologous platelet rich plasma (PRP) in the treatment of severe knee osteoarthritis.

This is a single centered, randomized, single blind phase II clinical study. Patients will be divided into two groups of case and control. Patients of case group will receive intra-articular injection of autologous AMSCs suspended in 3 ml autologous PRP for 3 times, patients of control group will receive intra-articular injection of 3 ml of autologous PRP for 3 times. The investigators designed this clinical study to evaluate therapeutic effects of AMSCs in patients with severe knee osteoarthritis.
