Knee arthroscopy is performed by inserting a special instrument called an arthroscope into the knee through a small incision. The arthroscope is a special camera and lens that the surgeon uses to see inside the joint. He views the camera image on a television screen while he is operating. The surgeon uses another small incision to insert arthroscopic instruments inside of the joint to perform the surgery.
This page contains photographs taken during real knee arthroscopies. First, we will show you the normal knee anatomy. Next, there are photos of various injuries and conditions, followed by post-treatment photos.
