Osteoarthritis is the most common type of arthritis, and is also known as degenerative joint disease. It can occur in nearly any joint in the body and is associated with a breakdown of cartilage in the joints. Most commonly, Osteoarthritis occurs in the hips, knees, and spine which are known as main weight bearing joints. It’s a condition that is ongoing, and will continue to be a thorn in your side if you don’t treat it properly.
