  1. To reduce pain
  2. To improve your function and quality of life

2The artificial joint is a replica of your own joint in size and structure, though one must realize that it does require some care and considerations. The uni and total knee replacement replaces each component of your own knee.

Before your surgery:

You may be required to consult a physician before you undergo surgery. This is a full medical examination to assess your health and to ensure you are fit to undergo surgery. Blood tests may be done, including cross matching blood incase a blood transfusion is required after surgery. This is rare, but a necessary precaution to take.

An ECG (electrocardiogram) ensures your heart is strong enough for the surgery. Chest X-Rays and a lung function test may also be performed. Take prescribed medications as you have been. And, remember to take these with you for the duration of your hospital stay.

Ensure you inform your surgeon if you are on chronic medication, and if you have any allergies. Inform your surgeon if you have had any recent coughs or colds, and if you suspect you may have any skin infection (this includes ingrown toe nails, and any scratch that may postpone your surgery). Make all necessary arrangements for home so your stay in hospital will be calm and help you recover.

3Your medical aid will authorize your stay in hospital. Please make sure you bring your membership card with you when you are admitted.

Before your surgery:

You will be required to have nothing to eat or drink for at least eight hours before your surgery. You will be admitted to a bed in the hospital and a nurse will take a medical history. You will be given a hospital gown to wear for surgery.

Your knee will be cleaned prepared for surgery. An ice pack may be put onto your knee. Your anaesthetist may give you a pre-medication to help you relax before going to surgery. The surgery is done in a sterile (ultra-clean) operating theatre.

You will find that you have a catheter inserted in your bladder. This is normal and allows your bladder to empty without you having to move. It will not be uncomfortable and will be removed once you are more mobile.

Your knee will be dressed in a bulky dressing, and you may have little or no feeling in your legs after your epidural anaesthetic. This is normal. Pain will be controlled, usually with a patient controlled pain pump, or with pain relieving medication as prescribed by your anaesthetist. This allows you to control any discomfort you may feel.

Nursing staff are available all the time, and will be available for your care and comfort. Please do not hesitate to call on them. Your drip will be removed once you are eating and drinking sufficiently, and once antibiotics that administered are completed. Your stay in the hospital will depend entirely on your progress. You will be visited by physiotherapists to get you up and doing some exercises. He or she will also get you used to using crutches, which you will be required to use for a time.

This helps to reduce swelling and pain. This should be used four times a day for 20 minutes at a time. You will be prescribed some pain medication and may be instructed to use medication to reduce the risk of blood clots.
