Please note, this page is printable by selecting the normal print options on your computer.

General Information
Microfracture surgery is a technique used to treat limited areas of damaged cartilage within the knee. Microfracture creates small holes in the bone. This stimulates new cartilage growth in a small area of damaged cartilage.

This is an arthroscopic operation, also known as keyhole surgery, therefore it is often done as a day case. It is very important to engage in a rehabilitation programme guided by your physiotherapist following this operation. This will optimise the success of the operation.

Advice Following Microfracture Surgery

Ice
To reduce pain and swelling wrap a bag of ice, or frozen peas, in a tea towel. Elevate your leg to above hip height and mould the ice pack around the knee. Leave for 15 minutes and repeat 3-4 times a day. Never put ice directly on the skin or leave an ice pack on for longer than 20 minutes as this can result in an ice burn.

Crutches
Following this operation you will need to use crutches. Your physiotherapist will teach you to use these and advise you as to how long you will have to use them for.

Brace
Some patients may be fitted with a knee brace to limit how far the knee will bend. Your physiotherapist will fit this and advise you as to how long it must be worn for.

Continuing your rehabilitation
You will be referred to see a physiotherapist as an outpatient once you are discharged from hospital. They will work with you to progress your strength, range of movement and mobility as appropriate.
