The knees are the largest joints in the human body. They are located between the two large bones of the legs, the femur (thigh bone) and tibia (shin bone). Knee joints are responsible for moving legs and body weight when standing or moving. As such, they are susceptible to injury or disorders that can cause pain or discomfort. A knee X-ray<\/strong> is the first step in detecting these injuries and disorders.<\/p>\n <\/p>\n This article explores what a knee X-ray<\/strong> is, how it works, common reasons for getting one, and its expected results.<\/p>\n <\/p>\n A knee X-ray<\/strong><\/a> is a procedure that uses (a form of radiation) for obtaining images of the knee structure that include the femur (thigh bone), tibia (shin bone), fibula and patella (kneecap). These X-ray<\/strong> images, known as radiographs, are used by doctors to examine damage to the knee bones, signs of infection, or changes in joint space.<\/p>\n <\/p>\n A knee X-ray<\/strong> uses controlled amounts of radiation, which pass through the body and produce an image on special photographic film or digital sensors. This radiation is absorbed in different amounts by your bones and tissue because of their thickness.<\/p>\n <\/p>\n The calcium in bone absorbs most of the radiation and appears white on the radiographs. Soft tissues like muscles, ligaments, tendons, and cartilage absorb less radiation and appear in varying shades of grey. Body fluids are radiolucent and thus appear in a dark tone in X-ray<\/strong> images.<\/p>\n <\/p>\n The health of a knee joint is affected by many things. A knee X-ray<\/strong> is usually the first diagnostic test recommended by doctors to determine the cause of the ailment. Some of the common reasons for a knee X-ray<\/strong> include:<\/p>\n <\/p>\n <\/p>\n The X-ray<\/strong> images of the knee joints are examined by radiologists or orthopaedists. A normal knee X-ray<\/strong> will vary from an abnormal one and show the following results.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Knees are the most used joints in the human body and play an essential role in walking, running, and supporting body weight. Any pain or discomfort in the knee or surrounding areas can indicate an injury or a joint disorder.

\nA normal knee X-ray<\/strong> shows bones with smooth edges, clear gaps, a perfectly centred kneecap, and no signs of fracture, thinning, or growth on bones. An abnormal knee X-ray<\/strong>, on the other hand, would show narrowed space, bone fragments and shadows of soft tissues in knee joints, jagged bones, and a tilted kneecap.<\/li>\n
\nKnee pain is serious if it is swollen, shows signs of deformity, or is unable to bear any weight. A knee X-ray<\/strong> can help in detecting the underlying cause of the pain.<\/li>\n<\/ul>\n
