This disease is becoming more common with the increase in average lifespam of the population all over the world. Fifty years back the average lifespan of Indians (called life expectancy at birth) was below 50 years and now it is more than 65 years. The same figures in Japan is close to 80 years and that of USA is 75 or so. This has happened because of improved health care, increased knowledge base about avoiding diseases and better living conditions. It is thus natural that with increased age, more people will suffer from degenerative diseases like Osteoarthritis Knees. It is estimated that about 40 million population (out of the total 260 million) of the United States of America (USA) suffer from this disease. About 70-90% of the aged people in that country suffer from Osteoarthritis Knee. It is estimated that by 2030,70 million Americans above the age of 65 will be at the risk of this chronic disease. In India, though the statistical figures are not available, the percentage is likely to be similar, if not more.
