What happens during surgery? icon plus
The procedure is usually performed either under general anaesthetic or under spinal or epidural anaesthetic (you're awake but have no feeling from the waist down).
The surgeon will make a cut at the front of your knee and remove the worn areas of joint. They will then insert metal and plastic implants to resurface the joint and are fixed into position using special bone cement. -
How to prepare icon plus
Your consultant will explain the procedure and answer any questions you might have. Because anaesthetic is normally used during the procedure, you will need to fast for a minimum period of six hours before the operation.
Your consultant will tell you how long you should avoid eating and drinking. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you. -
After surgery icon plus
You'll usually be in hospital for two to four days, depending on your progress and individual circumstances. You'll be kept comfortable following your operation and will be given medication for any pain during your stay.
You'll also be given exercises by a physiotherapist to aid your recovery. You should continue doing these at home. Remember that you’ve had major surgery and that you’re likely to feel tired and sore for a few weeks. Your recovery may take up to six weeks, and your consultant will let you know when you can get back to your normal routine.
