S83: Dislocation, sprain and strain of joints and ligaments of knee
S83.3: Tear of articular cartilage of knee, current
The knee joint connects the thigh to the lower leg. The knee joint is made up of 3 bones. These bones are the thighbone (femur), the shinbone (tibia) and the kneecap. The kneecap sits in a groove at the front of the thighbone.
The bones in a joint are covered with cartilage. When the joint is moved, the cartilage prevents the bones from rubbing against one another. The cartilage is normally strong and elastic, with a smooth surface.
You have injured your knee. In the process, your cartilage has torn. This may result in pain. The pain then usually occurs when you move. It may also be that you are no longer able to move your knee joint properly.
