Arthroscopy is a common surgical procedure in which a joint (arthro-) is viewed (-scopy) using a small camera. Arthroscopy gives doctors a clear view of the inside of the knee. This helps them diagnose and treat knee problems.
Technical advances have led to high definition monitors and high resolution cameras. These and other improvements have made arthroscopy a very effective tool for treating knee problems. According to the American Orthopaedic Society for Sports Medicine, more than 4 million knee arthroscopies are performed worldwide each year.
