Considering a knee Replacement?

A knee replacement is a surgical procedure, which involves replacing the ends of the two bones that form your knee with a metal implant. In most cases, the goal of the replacement is to reduce the amount of pain experienced around the knee.

The most common indication for needing a knee replacement is a combination of Osteoarthritis and pain. But having Osteoarthritis, doesn't automatically mean you need a hip replacement. In most cases, Osteoarthritis can be managed with exercise, activity modification and perhaps medication. When the pain is significantly impacting upon your lifestyle that surgery might be an option. 

There are two main types of knee replacement. A total knee replacement and a uni/partial (half) knee replacement.

How do I know if I need surgery?

Many of the common signs and symptoms of Osteoarthritis can be managed with a combination of exercise, activity modification, weight loss and medication. If you have not already done so, talk to a Physiotherapist who will be able to guide you towards the best type of exercise that is most suited to you. 
Remember, there is no current cure for Osteoarthritis. The treatments available aim to help you manage and reduce symptoms, not fully take it away.

If you have tried exercise, activity modification and medication and are still unable to manage the pain, an X-ray may be taken of the knee to look at the amount of change that has happened in the knee. It is important to remember that everyone is different and the amount of change we see on an X-ray does not equal the amount of pain or discomfort we experience.

You may be offered an injection into the knee joint to help settle the pain. The injection contains a powerful anti-inflammatory which can help to settle stiffness, pain and swelling. Injections are best used alongside graded exercise, as the stronger you can get the knee to be, the longer the injection can last. You can only have 1 injection every 12 weeks. This limitation is to help prevent further damage to the knee. 

If you have tried all of the options and  you have significant change shown on an x-ray, then you may be referred to an Orthopaedic Consultant. 

The decision to have a joint replacement should not be taken lightly. It is important to discuss everything with your family, friends, healthcare professionals and Doctor. The decision usually revolves around how much your knee is impacting YOU and YOUR daily life. If you are unsure of this impact, try the Oxford Knee Questionnaire here

Whilst you're waiting...

The current pressures on the NHS mean that you may have to wait a little longer to have your surgery. But whilst you're on the waiting list, there are a few things you can do to help yourself.

Get Active

Did you know that exercising other parts of your body can actually help improve your knee function? Swimming and cycling can be great ways to get more active. Moving your knee gently in a swimming pool can really help to improve the flexibility and build back some muscle. Our body takes time to adapt to getting active and you won't see changes straight away.
