Arthroscopy
An arthroscopy is a type of keyhole surgery used both to diagnose and treat problems with joints. It's most commonly used on the knees, ankles, shoulders, elbows, wrists and hips.
An arthroscopy can be carried out to help diagnose and treat a number of joint problems and conditions.
An arthroscopy procedure usually lasts between 30 minutes and two hours. You can normally go home the same day or the following morning.
How long it takes to recover after an arthroscopy can vary, depending on the type of surgery you had, your general health and the type of work that you do.
Ashley French, from north London, decided to go ahead with an arthroscopy after he noticed something was wrong with his knee. He hasn't looked back since.
