Knee Replacement (total)

Orthopaedic Surgery | NHS, Self Pay, Insured

What is a knee replacement?

Our knees come under a lot of pressure during our lifetime. Gradually the joint can become damaged or worn from ageing, arthritic conditions or injury. If you have been experiencing severe pain that does not alleviate with rest and affects your everyday mobility, quality of life and ability to work, your doctor may recommend a total knee replacement.

A total knee replacement is a surgical procedure to resurface the knee joint with artificial parts. This provides improved stability and mobility and helps to alleviate pain you may have experienced as a result of worn cartilage in the knee, from osteoarthritis or a previous injury.

Are there any alternatives to a total knee replacement?

Over the counter painkillers such as paracetamol and anti-inflammatory painkillers such as ibuprofen may help control the pain.
Supplements to your diet may also help relieve your symptoms, but you should always check with your doctor before you take these.
Using a walking stick can support your mobility and make walking easier, whilst wearing an elasticated support on your knee can help it feel stronger.
Regular moderate exercise can help to reduce stiffness in your knee.
Physiotherapy may help to strengthen your muscles over time.
A steroid injection into your knee joint can sometimes reduce pain and stiffness.

However, many people will find these measures become less effective if your arthritis gets worse or your knee joint is severely damaged and, depending on the severity of your condition, surgery may be the best option.

What does the operation involve?

The operation usually takes an hour to 90 minutes and there are various anaesthetic techniques available. You will have the opportunity to discuss this with our anaesthetist.

Your surgeon will make an incision on the front of your knee and remove the damaged joint surfaces, this involves removing the end of the thigh bone, and the top of the shinbone, and replacing them with prostheses (artificial knee implants). The artificial knee is usually made of metal alloy and high-density plastic. A plastic button may also be used to resurface the back of the kneecap if needed. Your knee replacement is fixed to the bone using acrylic cement or special coatings on the prosthesis that bond directly to the bone.

What complications can happen?

Benefits of knee replacement surgery

Data shows that, for patients over the age of 75 undergoing the most common types of total knee replacement, there is less than a three percent chance of requiring further surgery after thirteen years.

Approximately 85 to 90 percent of all total knee replacement operations performed are successful for approximately 10 to 15 years, depending on the patient's level of activity, after which time revision surgery may be recommended by your doctor.

You can experience freedom from pain, improved mobility and improved quality of life as everyday activities and exercise become much easier. You may or may not be able to return to active sports or heavy labour; you should follow the advice of your consultant on the levels of activity you can undertake.

Enhanced recovery programme

Having an operation can often be both physically and emotionally stressful. Sometimes referred to as rapid or accelerated recovery, enhanced recovery is a new, evidence-based approach that helps people recover from major surgery faster and get them back to full health as quickly as possible.

Our Enhanced Recovery Programme aims to ensure that patients:

Are as healthy as possible before receiving treatment.
Receive the best possible care during their operation.
Receive the best possible care while recovering.

Research has shown the earlier a person gets out of bed and starts walking, eating and drinking after having an operation, the shorter their recovery time will be.
