An arthroscopy is a surgical procedure that involves the surgeon creating a small incision in the area of a joint affected by arthritis or injury. While the patient is under anesthesia, a small camera fitted onto a narrow tube is inserted through the incision. The camera provides the surgeon with a view of inside the injured or arthritic joint.
An arthroscopic surgery can be a diagnostic or a treatment procedure involving other small surgical tools that clean or repair the injured or arthritic joint. Knee arthroscopy and shoulder arthroscopy are two common surgeries of this type.
