Treatment of Knee Osteoarthritis With Autologous Mesenchymal Stem Cells

Osteoarthritis is the most prevalent joint disease and a frequent cause of joint pain, functional loss, and disability. Osteoarthritis often becomes chronic, and conventional treatments have demonstrated only modest clinical benefits without lesion reversal. Cell-based therapies have shown encouraging results in both animal studies and a few human case reports. We designed a pilot study to assess the feasibility and safety of osteoarthritis treatment with mesenchymal stromal cells (MSCs) in humans and to obtain early efficacy information for this treatment.
