Osteoarthritis is a debilitating condition that affects more than 27 million Americans. It causes pain, stiffness, swelling and reduced mobility. Some people with osteoarthritis find it difficult just getting out of bed or getting up from a sitting position. Osteoarthritis can also damage muscles and ligaments, making it difficult to climb stairs or even climb into and out of the bathtub.
Osteoarthritis occurs when cartilage that supports and cushions the joints of the hands, spine, hips and knees wears away, and the bones rub against each other.
