Arthroscopy is a surgical procedure that gives doctors a clear view of the inside of a joint. This helps them diagnose and treat joint problems. During hip arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your hip joint. The camera displays pictures on a television screen, and your surgeon uses these images to guide miniature surgical instruments. Hip arthroscopy has been performed for many years, but is not as common as knee or shoulder arthroscopy.
