Transplantation of Bone Marrow Derived Mesenchymal Stem Cells in Affected Knee Osteoarthritis by Rheumatoid Arthritis

Osteoarthritis of the knee is one of the most common causes of disability among elderly. Arthritis rheumatoid is an autoimmune disease which causes multi articular arthritis, such as knee osteoarthritis. As the disease progresses the cartilage become frustrated, surrounding bone react to become thicker and inflammation occurs in subchondral bone seen in T2-weighted MRI as increase in signal density. Patients are treated initially by pain management. In patients who don't response to first line treatment invasive treatment like total knee replacement is done. The investigators designed this clinical study with the aim of evaluating therapeutic effects of intra-articular injection of bone marrow mesenchymal stem cells (BM-MSCs) in 60 patients with knee osteoarthritis.
