Cartilage in your knee joint has been smoothed out.

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.

When cartilage is worn or damaged, the affected areas can be smoothed out. In the process, any cartilage tissue that has become detached or is sticking out can be removed. The cartilage was smoothed out via an arthroscopy. An arthroscopy first involves making a small incision in the skin. A camera was pushed through this incision. This camera sends images of the inside of the joint to a screen. Instruments such as forceps and scissors can be inserted into the joint through other small incisions.
