A robotic knee replacement is the same as a regular knee replacement with the assistance of a robotic arm, resulting in greater precision and a more natural feeling knee.
Why use a Robotic-arm assisted Total Knee Replacement?
During a traditional knee replacement procedure, damaged tissue in the knee is removed and replaced with an artificial joint. A robotic-arm assisted knee replacement is the same procedure performed with the assistance of a robotic arm. Because the Robotic technology results in greater precision, surgeons can customize knee replacements to each patient’s anatomy, which in turn can result in more ‘natural feeling’ knee.
What does a Robotic-arm assisted Total Knee Replacement involve?
In the weeks before your Knee operation, a 3D CT scan of your Knee is undertaken, which is then processed by the Robot. Your surgeon, with the assistance of the Robotic Arm Technology, plans the surgical procedure within a fraction of a millimetre
Your consultant is always in control during the operation. However, the robotic-arm assisted technology allows the consultant to perform the joint replacement with pinpoint accuracy, tailored to your anatomy, Knee size and alignment. The robot does NOT perform the surgery, but during the operation, the robotic arm uses data from the 3D model to create a predefined space for the surgeon to work in, preventing them from accidentally damaging the surrounding tissue.
A Total Knee Replacement is usually done under a regional anaesthetic (which numbs you from the waist down) or sometimes under a general anaesthetic (which puts you to sleep).
The surgeon will begin by making an incision of around 10-15cm, allowing the kneecap to be moved aside and the damaged joint surfaces to be cut away. After testing the components for proper function, the parts of the new knee are fitted. The incision is then closed. A Total Knee Replacement usually takes about 1-1.5 hours depending on the type of procedure
