Learning About Your Knee Pain & Cartilage Damage

The surface of your knee joint is covered in articular cartilage. When you injure articular cartilage, you may experience pain or swelling—and you may have difficulty managing the simplest daily activities, such as climbing stairs.

Articular cartilage cannot heal on its own; worse, once the surface is damaged, the injury can possibly continue to slowly deteriorate. Small cartilage injuries can progress to larger cartilage injuries, and, if left untreated, may lead to a more serious knee condition, such as osteoarthritis (OA). OA, the most common form of arthritis—and the most common joint disease—can greatly limit your activity.
