Sometimes called “wear-and-tear” arthritis, osteoarthritis is a common condition that many people develop during middle age or older. Osteoarthritis of the hip causes pain and stiffness. It can make it hard to do everyday activities like bending over to tie a shoe, rising from a chair, or taking a short walk. Because osteoarthritis gradually worsens over time, the sooner you start treatment, the more likely it is that you can lessen its impact on your life.
