Knee Arthritis results from thinning of the cartilage of the knee joint, usually due to injury or ‘wear and tear’ (ageing).
There are three kinds of Knee Arthritis:
- Osteoarthritis, a degenerative disease that occurs as you age. This is the most common form
- Rheumatoid Arthritis, an autoimmune disease in which your body’s immune system attacks the joint
- Post-Trauma Arthritis, caused by direct trauma to the knee that damages the cartilage and changes the joint mechanics
