About Arthritis

Arthritis is a disease resulting in damage of joint cartilage, the tissue that covers the ends of your bones. This damage can cause you severe pain, stiffness, disability and deformity. These symptoms can interfere with your basic daily tasks such as walking, driving a car and preparing food. The severity of symptoms can vary from mild to moderate or severe.

Arthritis is an umbrella term for many conditions affecting the joints, the most common of which is osteoarthritis.

What is Knee Osteoarthritis?

Osteoarthritis is wear and tear in a joint. It can affect main structures in your body including bone, cartilage, ligaments, and tendons. In knee osteoarthritis, cartilage in the knee gradually wears away, becoming frayed and rough, reducing the protective space that typically exists between the bones. As a result, this often results in a painful bone rubbing on bone feeling.2
