Total Knee Replacement

Before your admission it is helpful for you to read the consent and information about the type of knee replacement you are going to have which will be sent to you or can be downloaded here.

Simon’s preferred total knee replacement is the Attune knee replacement manufactured by DePuy.  This knee replacement was launched in the United States in 2010  and the UK in 2012.  As this knee replacement does not yet have a 10 year track record Simon follows the recommended guidelines of entering your information into “beyond compliance”.  This requires you to sign a separate consent form to allow your data to be shared with the company who manufacture your knee replacement.  This can be downloaded here. 

More information about the outcome of the Attune knee replacement in general can be found here.  The purpose of beyond compliance is to ensure an early warning system should there be any concerns about the longevity of this knee replacement. 

In 2017 the 4-year outcome data from the National joint Registry was presented which reveals that this joint replacement is performing better than the average.  There have been a number of presentations which suggest that this knee replacement is associated with less anterior knee pain (pain at the front of the knee) and better stability whilst descending stairs than its predecessor.  Clearly the long-term outcome of this knee replacement remains as yet unknown;  however the results to date are very positive.

Following knee replacement you will usually be in hospital for 2 or 3 days depending on how well you can mobilise. In order to be safe to be discharged home you will be seen by the physiotherapists on a regular basis who will encourage you to move the knee as much as possible and provide you with exercises to practice.  You will be provided with an ice pack to reduce swelling and help pain which you should use both in hospital and following discharge as much as possible.  Once the physiotherapists are happy with your progress and you are safe on stairs, provided there are no medical problems Simon will be happy for you to be discharged home. 

In order to reduce the risk of deep vein thrombosis you will have been given injections into the abdomen whilst in hospital.  It is imperative that these are continue for 2 weeks following your surgery )unless alternative arrangements have been agreed with Simon) to minimise the risk of deep vein thrombosis.  This is a serious condition and can occasionally result in pulmonary embolism. Following joint replacement surgery you should not fly for 6 weeks and should avoid a long-haul flight for 3 months because of the increased risk of deep vein thrombosis
When you are discharged home if needed you will be provided with a certificate signing you off work for 6 weeks.  You will be signed off work for 6 weeks.

In terms of returning to driving you should take 6 weeks off driving unless your left knee has been replaced and you drive an automatic.

Arrangements will be made for you to be followed up by the physiotherapists but nevertheless please remeber it is really important that you continue to do the exercises you were shown in hospital at home. 

You should take regular painkillers as needed – usually a combination of Ibuprofen and Paracetamol with codeine is sufficient.  

You will be given an appointment for your clips to be removed 2 weeks following your surgery.  You will also be given an appointment to be seen by Simon about 6 weeks following surgery when he will reassess your knee and discuss return to work and driving. 

If needed Simon will then arrange to see you again at the 3-month post-operative stage.  It takes approximately a year to reach an endpoint in recovery following joint replacement.
