Arthritis of the Knee

Knee arthritis arises when cartilage or the surface of the knee joint wear out. Worn out cartilage (also referred to as osteoarthritis of the knee) is the most common form of arthritis and can lead to bone ends rubbing together (bone on bone). Wear and tear to the surface of the knee joint prevents smooth movement. Ultimately, knee arthritis surgery may be required.
