Autologous Bone Marrow Mesenchymal Stem Cells Transplantation for Articular Cartilage Defects Repair

Autologous Bone Marrow-derived Mesenchymal Stem Cells Used in the Treatment of Articular Cartilage Injury

This is a non-randomized study aimed to determine the safety and efficacy of intra-articular injection of autologous bone marrow-derived mesenchymal stem cells in patients with knee articular cartilage defects.

Osteoarthritis is the most prevalent joint disease, create articular cartilage defects is a frequent cause of joint pain, functional loss, and disability. Osteoarthritis often becomes chronic, and conventional treatments seek to ameliorate pain or improve mobility. However, these treatments rarely modify the course of the disease.Recent studies cell-based have shown encouraging results in both animal studies and a few human case reports. We designed a study to assess the safety and efficacy of osteoarthritis treatment with intra-articular injection of autologous bone marrow-derived mesenchymal stem cells.

Inclusion Criteria:

• Diagnosed with mild to moderate osteoarthritis (visual analogue scale)
• History of joint swelling, pain, stiffness, altered gait and loss of motion due to degenerative cartilage

Exclusion Criteria:

• Any past history of neoplasia and primary hematological disease
• Autoimmune disease or the medical history
• Systemic bone or cartilage disorders
• Acute or chronic communicable diseases including Hepatitis B, Hepatitis C and HIV
• Co-morbidity which the physician deems as a contraindication to stem cell transplantation and bone marrow biopsy
• Evidence of infection or fractures in or around the joint
• Contraindication to bone marrow aspiration
• Deviation from the axial axis (varus or valgus) greater than 12 degrees.
