Arthroscopy is a surgical procedure doctors use to look at, diagnose, and treat problems inside a joint. It’s a minor surgery and is done on an outpatient basis, which means you can go home the same day. Your doctor may recommend it if you have inflammation in a joint, have injured a joint, or have damaged a joint over time. You can have arthroscopy on any joint. Most often, it’s done on the knee, shoulder, elbow, ankle, hip, or wrist. During the procedure, your doctor will insert a tool called an arthroscope into your joint through several small cuts to see how much damage is in the joint. They can also repair many injuries during arthroscopy
