Partial Knee Replacement

The treatment for knee arthritis depends on the severity of your symptoms.  Sometimes arthritis may affect only part of your knee joint;  for example if the arthritis affects only the medial compartment of the joint, as shown on this xray, a partial knee replacement to replace just the medial half of the joint can be the appropriate choice.

Simon uses the Oxford partial knee replacement  produced by Zimmer Biomet which has an excellent track history.  This partial knee replacement is inserted without bone cement and gradually bonds to your native bone. 

Details of this partial knee replacement can be found here and consent information about partial knee replacement can be found here.

An Oxford partial knee replacement is usually carried out under a spinal anaesthetic.  At the time of surgery final checks are made on the condition of the remainder of the joint to ensure that your knee is appropriate to receive an Oxford partial replacement.  In general the post-operative recovery following a partial knee replacement is more rapid than a total knee replacement with many patients being discharged home on the first day following surgery. 

Following your surgery you will have an x-ray to check the position of the prosthesis and will be mobilised by the physiotherapists progressing rapidly to crutches.  It is important to move the knee as much as possible and to practice the exercises provided.  An ice pack will be provided to reduce swelling and assist with pain control.  You will also be provided with regular painkillers which are important for you to take. 

As with all knee surgery, there is a risk of deep vein thrombosis and you will be given injections into the abdomen whilst in hospital.  These need to continue for 2 weeks following your surgery unless  alternative treatment has been discussed. 

In addition to regular injection treatment you will also be provided with anti-embolism stockings which are to be worn for 6 weeks.  Because of the increased risk of venous thrombo-embolism you should avoid flying for 6 weeks and long haul flights for 3 months.

When you are discharged home you will be provided with a certificate signing you off work for 6 weeks if needed and you should also plan to take 6 weeks off driving unless surgery has been carried out to your left knee and you drive an automatic. 

Arrangements will be made for you to be followed up by the physiotherapists, but nevertheless please remember it is really important that you continue to do the exercises you are shown in hospital once you get home.  You should also continue with regular painkillers as needed - usually a combination of ibuprofen and paracetamol with codeine is sufficient.

Your wound will be closed with clips and arrangements will be made for these 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 the need for ongoing physiotherapy, your return to work and to driving.  If needed Simon will then arrange to see you again at the three-month post- operative stage. 

It can take approximately a year to reach an endpoint in recovery following any type of joint replacement.
