If the joint is infected, you will need treatment with antibiotics, in hospital initially.

An arthroscope and a probe are inserted into the joint, allowing the surgeon to inspect the joint. The probe can be used to manipulate the cartilage and improve the view.
In arthroscopy, the Inside of a joint, such as the knee, is inspected using a viewing instrument called an arthroscope. The procedure is usually performed under a general anaesthetic. The arthroscope is inserted into the joint through a small incision in the skin, and the view from the arthroscope is displayed on a screen. Very small instruments can then be passed down through the arthroscope or inserted into the joint through other small incisions. Guided by the view on the monitor, the surgeon is able to carry out procedures such as repairing torn ligaments or removing damaged cartilage. Fluid passed down a tube is then used to wash away the debris from within the operating area.

J15> Swollen ankles
If you are pregnant, see chart 146, Swollen ankles in pregnancy (p.283). For painful swelling of one or both ankles, see chart 110, Painful joints (p.228). Painless swelling of the ankles is most often caused by fluid accumulating in the tissues after long periods of sitting or standing still. It is also common in pregnancy due to increased pressure on blood vessels in the abdomen. However, occasionally, swelling of the ankles may be due to a potentially serious heart, liver, or kidney disorder. If you frequently have swollen ankles, consult your doctor.
