Abstract

Background : Osteoarthritis knee is a musculoskeletal disorder characterized by stiffness and joint pain resulting in decreased physiological ability or quality of life of the elderly. To stabilize the knee and stop it even worse, the strength in the quadricep muscles and knee joint muscles is very important.
