Arthroscopy-X-rays

=Arthroscopy= **Arthroscopy is when a doctor makes a small incision in your knee and puts a arthroscope in it to see the damage. If there's damage, another small incision will be made for small instruments to go in and repair the the knee. Before 1790, a doctor had to make a big hole to see your knee. But that all changed when arthroscopy appeared.**

=**X-Rays**= **A X-Ray is when you're passed in front of a machine that can take a picture of the bones in your body. But sometimes you are held still well the machine works. X-Rays can be used to see if you're carrying a weapon on an airplane or into a secure place, or to see if you have a broken bone.**
