With 30 million people diagnosed in the United States, osteoarthritis (OA) is the most frequently occurring type of arthritis. OA is also known as “wear and tear” arthritis and degenerative joint disorder. The typical areas of the body where it develops are the knees, hips, and hands. As the disease develops, a joint’s bones and cartilage progressively degrade. The condition, which is a top reason that people become disabled, leads to inflammation, limitations to range of motion, and chronic pain.
