Knee bones look high: First, seen in people who are relatively thin or malnourished, which can lead to a significant protrusion of bone in the knee area and will see a high knee bone. Second, in people with degenerative osteoarthritis of the knee joint, there is obvious osteophytes around the knee joint, and the bones in the knee area will be seen to be significantly higher. Third, seen in patients with osteochondroma in the knee joint area, the chondroma expands outward and a significant increase in bone in the knee area will be seen. Fourth, it is seen in patients with fractures in the knee area, and later on, when the bone deformity heals, an abnormal protrusion of bone is seen, which leads to a very high knee bone.
