Griffin, et al (2010) who stated that Osteoarthritis is a progressive, age-related disease, also Lems, et al (2010) postulated that osteoarthritis affects more than half of older persons. Das, et al (2008) confirmed that age is the most powerful risk factor. The prevalence rises with increasing age across all populations, both for symptomatic and asymptomatic radiological osteoarthritis. Huskisson, et al (2010) showed that the disease becomes symptomatic in 15% of all adults > 40 years of age. Lawrence, et al (2008) reported that OA increases with age, the incidence of this problem begins to rise in the mid-forty.Ding, et al (2005) estimated that -on radiographic bases- osteoarthritis affects 25-30 % of persons aged 45-64 years, 60% of persons older than 65 years and more than 80% of persons older than 75 years. Role of aging in development of osteoarthritis is explained by Abramson, et al(2009) Age-related mechanical stress on joint cartilage may arise from a number of factors, including altered gait, muscle weakness, changes in proprioception, and changes in body weight. In addition, age-related morphologic changes in articular cartilage are most likely due to a decrease in chondrocytes’ ability to maintain and repair the tissue.
