An arthroscopy is performed under a general anaesthetic, so you will be asleep for the procedure. Small, minor cuts are made in the area to allow your surgeon to insert an instrument called an arthroscope, which is a thin tube which has a light and a camera on the end of it. The images are sent from the arthroscope onto a screen which allows your surgeon to be able to see into the joint.
Your surgeon is also able to perform treatment if necessary, such as removing affected tissue or cartilage within the joint. The procedure usually lasts between 30-45 minutes.
An arthroscopy is usually performed as a day case procedure, which means there is no need for an overnight stay in hospital, and you will be allowed to rest and recover at home.
