Arthroscopic surgery on the foot and ankle may be used as a diagnostic or treatment procedure, or both.

First, a small incision is made in the skin and a small instrument called an arthroscope is placed through it. A very small camera is then inserted through the arthroscope, allowing the surgeon to see the what is required. Other instruments can also be inserted through the arthroscope to make corrections, if required.

Because arthroscopy is less-invasive than traditional surgery, it reduces the risk of infection and swelling, and usually results in significantly faster healing and recovery. Most arthroscopic procedures on the foot and ankle are performed under local anaesthetic on an outpatient basis.
