Osteoarthritis of the knee joint is a common and frequent disease in the elderly, long with pain around the knee joint, pain at activity, pain at rest, pain going up and down stairs, deformation of the knee joint, and stiffness of the joint in the morning. X-rays show osteophytes around the joint and thinning or no cartilage on the joint surface. After the age of 45, the joints start to degenerate, and most people go out for an hour or more in the morning and evening after retirement. This is a bad habit that accelerates the wear and tear of the joint surfaces of the femur and tibia, which also increases joint degeneration and causes periarticular pain. Other diseases around the knee can also cause joint pain, such as cartilage degeneration disease of the patella and periarticular pain caused by hypertrophy of the joint capsule around the knee. These pains can affect people’s daily life, and the treatment cannot be completely restful because people always have to move around, and once they do, it offsets the treatment. The heavier the pain, the more it causes joint effusion, joint deformation, knee squatting, or worse, not even being able to get out of the house, the more painful it is to walk, and the more often you wake up at night with pain. As a reminder, anyone with knee pain should walk less, eat more food with high calcium content, such as shrimp, soy juice, milk, but also often sun exposure, activities to do thigh muscle training without weight, for example: sitting on the edge of the bed to do hooked leg extension and straight after a few seconds pause, each time ten groups, each group of ten times. Prone bed, do the back side of the hook leg is also each time ten groups, each group of ten times, side lying position legs straight, in the upper leg up flat, the higher the better, is also each time ten groups, each group of ten times, repeated practice of the other leg. Practice two or three times a day to prevent further development of the disease, but also to treat and relieve pain around the knee joint.
