Arthritis is a medical condition in which inflammation develops in the joints of the body. It is commonly known as a joint disease that causes pain, swelling, stiffness, and difficulty in movement. Although arthritis can affect anyone, it is more commonly seen in women than in men.

In India, approximately 180 million people are affected by arthritis. According to the 2019 Global Burden of Disease, Injuries, and Risk Factors Study, around 62 million people in India are affected specifically by knee arthritis.

According to the Centers for Disease Control and Prevention, there are more than 100 types of arthritis. However, only a few types are commonly seen in the general population. Some major types of arthritis are:

• Osteoarthritis: This condition mainly affects the knees. It causes pain, swelling, and stiffness in the joints, making movement difficult.
• Septic Arthritis: This type occurs when a bacterial infection affects the joints, leading to inflammation and severe pain.
• Rheumatoid Arthritis: An autoimmune disease in which the immune system attacks the joint tissues, causing pain and swelling.
• Juvenile Arthritis: This type usually affects children and causes joint pain and stiffness at a young age.
