Preparing for your knee replacement operation at the Elective Orthopaedic Centre, Kent and Canterbury (K&C) Hospital

A patient's guide

A joint replacement operation is done to improve your quality of life. It will hopefully allow you to do some of the things you want to in life, that have become difficult with your joint arthritis.

This booklet has been written by the teams who will look after you during your hospital stay. It aims to help you understand your surgery, and how you can best prepare and recover afterwards.

What is covered in this booklet?

This booklet will guide you through the various stages of your operation.

Welcome to the Elective Orthopaedic Centre

The Elective Orthopaedic Centre or EOC, is based at the Kent and Canterbury Hospital. This centre has been completely renovated and opened in August 2021.

This centre offers treatment to people across the south east of England.  

The unit is an elective care centre, which means that we only treat patients who have planned surgery. This means that the chance of your operation being cancelled is low, compared to having it in one of our busy general hospitals. Emergency surgeries at these hospitals can often cause planned care to be cancelled.

For more information about the hospital, please visit our website.

  • Attaching monitoring equipment and a drip

    One of the team will attach some standard equipment to you. These will monitor your heart, blood pressure, and oxygen levels during your operation.

    Your anaesthetist will give you medicine through a drip in the back of one of your hands. These include antibiotics, anti-sickness medicines, and fluids.

What happens in the operating theatre?

Once you are in the operating theatre, your whole leg will be painted with some cleaning fluid and covered with drapes. You will not be able to see the surgery. The spinal block will prevent you from feeling any of the operation.

Some people find listening to music through their headphones to be a good distraction. It helps them to relax; this will be offered to you. You may wish to bring your own music on your phone or portable music device, and your own headphones.

Some people prefer to have sedation, so they have a light sleep through their surgery. Your anaesthetist will discuss and agree with you a plan depending on your medical history, and your wishes.

After your operation, you may or may not recall hearing noises and conversations during the procedure. This is normal and will not be distressing. The anaesthetic staff will be with you throughout your operation to reassure you.

How long does the operation take?

The operation usually takes about 1½ hours.

What happens after my operation?

You will be transferred to the recovery area, where the nurses will monitor your blood pressure and pulse. Specialist nurses will care for you, making sure that you are comfortable and safe, before you are moved to the ward.

When your spinal anaesthetic has sufficiently worn off, our nursing and therapy teams will help you move out of bed. They will help you to stand and practise walking with suitable walking aids. It is important that you do this as early as possible. You need to be confident that your new joint will work. And moving around helps with:

The team will practise with you:

  • Will I be in pain?

    Joint replacement surgery is painful, just like any other surgery. The first few weeks can be a difficult time. However, it is important to stay active and do your movement exercises. We will give you strong pain relief medication. However, you should expect there to still be mild to moderate pain when you move. You will not be completely pain-free.

    The pain relief you are given after your surgery should control your pain as well as possible. It starts from the day of your surgery, and continues after your discharge home. We will give you the same pain relief tablets whether you stay in hospital overnight, or return home on the same day as your operation.

    In order for the pain relief to work, you must take your medicine as advised by your doctor or nurse.

What will happen when I get home?

When should I contact the hospital?

What support will I have once I return home?

The ward team will let you know about any follow-up appointments you may have. Including a routine follow-up telephone call to check on you a few days after your discharge.

Remember, that even after you are discharged from hospital, you are not alone. There is always someone available for you can contact for advice. You will be given information before you go home about who to contact should you need any help.

If you would like more information before your operation or have any questions in the first seven days after you have been discharged home, please ring Invicta Ward on 01227 866392. One of the nursing staff will be able to advise you, or they will contact a member of your surgical team for you.

For therapy related queries, please contact us on either 01227 766877 extension: 722 5421 or email. There is an answer service, so please leave a message with your name, hospital number and a contact number, and we will call you back.

If you are unable to contact one of the Invicta Ward team, please ring your surgical consultant’s base hospital. Ask to speak to their secretary, who will be able to help you contact one of the team. Contact information can be found on your letter. If you do not have this, then please ask for this on the day of your surgery.
