Thiruthopu Nimbagiri Swamy

Knee Osteoarthritis (OA) is a common form of arthritis that affects knee. It affects the bones, the cartilage (slippery tissue which provides a smooth surface for the motion of a joint and acts as a cushion between the bones), and the synovium (is soft, and it lines the joints, It produces synovial fluid, which helps in lubrication, also supplies nutrients & oxygen to the cartilage) in the knee joint.

Knee Osteoarthritis is also known as Degenerative Arthritis of the Knee. It is defined by degeneration of the knee’s articular cartilage, it develops when the cartilage of the knee wears off which leads to an overgrowth of the bone underneath. The cartilage becomes rough and breaks down, mainly resulting in swelling, difficulty in moving knee joint, and pain. Generally, OA can develop at any age but it is most frequently found to develop in 50+ age group people. Women are more likely to have osteoarthritis than men.
