Arthroscopy

Test Overview

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 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 incisions.

Like open surgery (which is done using a larger incision), arthroscopy allows your doctor to see what is wrong with your joint. However, compared to open surgery, arthroscopy:

• Is usually less painful.
• Is usually less costly.
• Usually allows for a quicker recovery time, depending on what is done.
• Can be done on an outpatient basis without requiring an overnight stay in a hospital. Open surgery often requires an inpatient stay in the hospital.

Should I have an MRI or arthroscopy to diagnose a possible torn meniscus?
