What Is Osteoarthritis Of The Knee?

Osteoarthritis otherwise known as the ‘Wear and Tear’ arthritis is the problem faced when the natural soft cushioning protection between the cartilage joints wears away. As and when this happens, the joints rub against each other in the absence of the cushion, and the shock-absorbing ability of the cartilage is gone or decreased. This action of rubbing against each other results in swelling, ache, stiffness, lowered mobile ability, and at times formation of bone spurs, which is the little outgrowth of the bone. As we grow, almost everyone develops Osteoarthritis of the knee, if not to a severe level at least to some degree. But young people also may develop this problem because of any possible reason.
