Knee pain is more widespread in middle-aged and elderly people, and most of them have osteophytes on their X-rays, which means that there are more bones. However, the majority of middle-aged and elderly people have osteoporosis, which means that there should be less bone in the knee joint. So, is there more or less bone? How can we explain this? The middle-aged and elderly have osteoporosis of the lumbar spine, which is clear from both photographs and bone densitometry; however, these are the people whose photographs reveal osteophytes in the lumbar spine. Tell me if this bone is more or less, why? Osteomalacia is a manifestation of degeneration and aging of the joint spine, why would it increase? Because the bones are lax and do not give strength. The human body is forced to increase the multiplier area of the bones, that is, osteophytes. The root is in osteoporosis. The symptoms of arthritis come very slowly. Most of them are in the weight-bearing joints, such as the knee, spine, hip and foot joints. Pain: When moving the joints, such as going up and down stairs. Stiffness: No longer as flexible as before. Swelling: Sometimes you can hear bone rubbing against bone in the swollen joint If these symptoms appear in one of your joints and have persisted for more than two weeks, you should go to the hospital. The knee joint is primarily a support structure made up of bones in the direction of the thigh and upper calf, with a layer of cartilage attached to the surface of the bones, which acts as a cushion against pressure and impact. Pain, swelling, difficulty walking up and down stairs, and inability to walk are often the first things to go wrong with the supporting structure, and the root cause is osteoporosis. The relationship between cartilage and bone is like a layer of PVC plate on the ground, the foundation is solid, PVC plate running cars are no problem; if the foundation is hollow, put a tire can collapse the plate, lose shock absorption, smooth performance. Without cartilage plate, it is inevitable that the bone and bone friction. Pain, bone flab due to this.
