Surgery

What should I do before admission?

What will happen during the surgery?

The surgery will be conducted under full body (general) or half body (regional) anaesthesia.

• Stop smoking immediately. Nicotine is known to slow down the healing process.

• Your doctor or anaesthetist may advise you to stop taking certain medications and dietary supplements before your surgery.

• On the night before surgery, do not eat anything after midnight.

• You may have a small amount of water (approximately 100mL) before 5am on the day of surgery.

• Shower before coming to the hospital.

• Remember to remove all hair pins, nail polish and jewellery before admission.

The worn out area of the joint will be removed through carefully measured bone cuts. Implants will then be inserted onto the cut bone surface. The knee will be balanced, stabilised and a good range of motion ensured. The wound will then be closed and dressings applied.

How long will the surgery take?

Depending on your condition, a typical knee replacement surgery lasts about two to three hours.

What can I expect immediately after the surgery?

You will be transferred to a recovery area for monitoring until you are fully awake. When the anaesthesia drugs are discontinued, you will gradually wake up. You will probably feel groggy and a little confused. Other common side effects include:

• Nausea

• Vomiting

• Dry mouth

• Sore throat

• Headache

An X-ray will be performed before your transfer to the ward.

You will then be moved to the ward, where you will stay before going home. You may feel some pain, but medication prescribed by your doctor will help control it.
