Arthritis is the breakdown of tissue (cartilage) that cushions your joint. It can cause pain and stiffness. Knee arthritis happens when the cartilage in your knee joint wears down. This can cause the bones to rub together.
Symptoms can be mild to severe. They may include pain and stiffness in the knee. You may feel stiff when you get up in the morning. You may have trouble walking. Your knee may look swollen or deformed, and it may make creaking or cracking sounds.
