Retrospective analysis of role of autologous bone marrow derived mononuclear stem cells in the management of degenerative arthritis of knee

Osteoarthritis (OA) Knee is the most common disease of the joints and a leading cause of chronic disability, especially in the aged population.1 The pathogenesis of OA knee has been linked to biomechanical and biochemical changes in joint cartilage, e.g. inability to withstand normal mechanical stresses, limited nutrients and oxygen supply, inadequate synthesis of extracellular matrix components, increased synthesis of proteinases and overall apoptosis of chondrocytes.2–5 Synovial inflammation is a response of synovial macrophages to cartilage debris and catabolic mediators entering the synovial cavity which limits the cartilage repair.6
