It is not uncommon for aging knees to make cracking or popping sounds when in motion, however, combined with knee soreness and stiffness from sitting for long periods of time or overuse, such symptoms could indicate osteoarthritis. Taiwanese geriatrician Dr. Yu-Hsieng Fu introduced four ways to prevent and improve the conditions of osteoarthritis.
Osteoarthritis is also known as degenerative arthritis. When the joint area is worn down by friction through excessive use of the cartilage or by abnormal secretion of synovial fluid, the cartilage between the bones gradually loses elasticity and becomes thinner. Eventually, the cartilage wears out completely, leaving gaps between the bones and leading to a lack of cushioning lubrication. This causes more friction between the bones, resulting in osteoarthritis.
