According to the Arthritis Foundation, over 50 million Americans have arthritis. The most common form of arthritis is osteoarthritis, which is a degenerative joint disease. Though it can occur in younger people, it often affects people 50 years of age and older.
Osteoarthritis (OA) is a chronic condition that causes the cartilage between the joints to break down. Cartilage behaves as a cushion for joints and protects the surface of the bones. Without this cushion, bones can rub or grind together, causing pain, stiffness, and swelling.
Doctors may recommend physical therapy, a knee brace or other self-care measures to help with the pain and discomfort of OA. For some individuals, oral medications may also relieve knee pain.
If a patient continues to experience discomfort, swelling, or have extensive joint damage, their doctor may suggest other options. They may require knee injections or even a full knee replacement.
