Osteoarthritis is the most common form of arthritis in the knee joint. Osteoarthritis develops slowly and the pain it causes worsens over time.
Causes of Knee Osteoarthritis
Osteoarthritis is degenerative and is caused by “wear-and-tear”. Over time the cartilage in the knee joint gradually wears away. Eventually the space between the bones decreases as shown in the image.
