Arthroscopy is a surgical procedure that
allows your doctor to look at the inside of a joint in your body through a thin
viewing instrument called an arthroscope. Arthroscopy allows your doctor to
look at the joint surfaces and the surrounding soft tissues, such as tissue
that connects bone to bone (ligaments) and the tough tissue that
covers the ends of the bones at the joints (cartilage) and
provides a cushion between the bones. This procedure can be used to diagnose a
joint problem, perform surgery that repairs a joint problem, remove a loose or
foreign body, or monitor a disease or the effectiveness of a treatment.
Arthroscopy is commonly performed on the knee, shoulder, and ankle. It also can
be done on the hip, elbow, and wrist.
During arthroscopy, the
arthroscope is inserted into your joint through a small cut (incision) in the
skin. The arthroscope has a light source and a video camera attached to it.
Images from the camera can be seen on a video monitor. These magnified images
provide a clear picture of your joint. A sample of joint tissue can be
collected during arthroscopy for biopsy. If surgery is done, additional
instruments will be inserted into your joint through other small
