Knee replacement (arthroplasty)

A knee replacement (arthroplasty) is a common type of surgery where a worn, damaged or diminished knee joint is replaced with an artificial joint. The procedure has a high success rate, and is designed to greatly relieve pain, improve your range of movement and give you a significantly improved quality of life.

Who is suitable for a knee replacement?

Most patients that choose knee replacement surgery suffer from osteoarthritis or other knee conditions such as rheumatoid arthritis and psoriatic arthritis. Adults of any age can be suitable for knee replacement surgery, though most patients are between the ages of 55 and 80.

What does a knee replacement involve?

Knee replacement surgery usually takes one to two hours and patients are usually placed under general anaesthetic or have an epidural. During the surgery, your surgeon will make a cut on the front of your knee to remove the damaged joint and replace it with a prosthesis. The operation may be performed with the assistance of a robotic device (your surgeon will discuss this with you if so).

What can you do to prepare for a knee replacement?

A knee replacement is a significant operation. Ahead of it, it helps if you can stay active and do gentle exercise, particularly strengthening your quadricep muscles. This will help you cope with the operation and build strength afterwards.

What is the recovery period?

The length of time it takes to recover after knee replacement surgery depends on various factors, including your age, fitness level prior to your surgery and pre-operative range of knee motion. Most patients only need to spend around three days in hospital. Our dedicated recovery team of specialist orthopaedic nurses and physiotherapists will work with you closely to make sure you build strength and mobility as quickly as possible.

Self-pay package

As well as working with all major insurance companies, we also welcome patients who wish to pay for themselves. We offer a range of self-pay package options, including:

  • Hospital Packages: these are flexible packages that group standard diagnostics and the procedure into one clear price. Consultant and anaesthetist fees are separate, and any other addition to your treatment is billed separately.
  • Fixed Price Packages: these are comprehensive, all-inclusive packages that group everything you may need for treatment into one clear price. All of our Fixed Price Packages include pre-admission tests, procedure, professional fees, post-op outpatient care and any other consultant-recommended services as part of your treatment.
