ROBOTIC TOTAL KNEE REPLACEMENT

A surgical robot helps the surgeon to position the knee replacement components individually with better precision than by using conventional instruments. It can also facilitate smaller incisions and less blood loss, both of which can contribute to a quicker recovery.

​

DO I NEED A KNEE REPLACEMENT?

Indications for a robotic knee replacement are the same as for a conventional one. It is the ultimate solution for the pain caused by arthritis in the joint when lifestyle changes, exercise and medication are no longer enough to manage your pain. You can find further advice on these here. If you still cannot walk as much as you would like because of pain or cannot sleep the time has come to consider surgery.

The NJR decision support tool can help you get an idea of what you can expect from the surgery.

WHAT IS INVOLVED?

• If you decide for a robotic knee replacement you have the option of obtaining special x-rays or a scan to aid the planning, although this is not absolutely necessary.

• Preparing for your operation

  • We need to make sure you are as fit and prepared as possible to minimise the risk of complications and to ensure a speedy and smooth recovery. You will have a pre-assessment to identify any correctable abnormalities such as high blood pressure, anaemia​ and diabetes. It is advised that you stop smoking and try to loose weight if applicable. If you have a BMI of 40 or more we may have to postpone your surgery until you can loose some weight.

  • We will ask you to take part in a joint replacement class which is run by our physiotherapists. This is an invaluable resource to prepare you for your joint replacement journey from pre-surgery exercises to rehabilitation afterwards.

• Surgical procedure

  • Knee replacement requires a general or spinal anaesthetic and the consultant carrying this out will discuss with you which one is best considering your circumstances and preferences.

  • During surgery a cut is made over the front of the knee and the joint is exposed. The robotic trackers will be placed and secured to the thighbone from within the main incision and via two small stab wounds over the shinbone. A series of measurements are taken so the robot knows where your knee is in space and how to best position the implant in your knee. The damaged joint surfaces are the removed using the robotic arm and the bone is ​prepared for the artificial components. The robotic trackers are removed and the implants are fixed to the bone using special bone cement. To conclude the operation the soft tissues and the skin are carefully closed.

• Recovery

  • We aim to get you back on your feet and walking on the day of your operation. We will keep you comfortable using the least possible amount of pain medication.

  • Our physiotherapists will guide you through the process of how to get in and out of bed and use any walking aid you may require. All being well you can go home after one or two nights in hospital.

  • We will give you an exercise program for home and our physiotherapists will assess your progress regularly. You can walk and use your knee as you are comfortable.

WHAT ARE THE BENEFITS?

• All knee replacements aim to provide pain relief, increase range of movement and correct bow or knock knee deformities.

• Robotic knee replacement allow for more precise and personalized positioning of the replacement components.

• There is less bleeding as the the canal of the thighbone does not need to be opened..

• Potentially better movement and more natural feel to the knee.
