MAKO Robotic Hip and Knee Surgery

What is Mako Robotic Surgery?

The accuracy of Mako robotic surgery is not dependent on surgeon "feel" or experience

The Mako Robotic-Arm is at the forefront orthopaedic technology. The system is designed to minimise the margin of error to allow for very precise component placement during total hip, total knee and partial knee replacement surgery. 


Whilst the robot guides the operation, the surgeon remains in charge and responsible for every step of the procedure. The Surgeon is able to make changes to the technical plan during the operation according to the condition of the bone and soft tissues as encountered. However, unlike traditional joint replacement surgery, the accuracy of the Mako technique does not rely on surgeon "feel"and experience. 

What are the advantages of MAKO robotic surgery?

The success of a hip or knee replacement requires accurate reconstruction of normal joint anatomy, movement and stability. If this is not done correctly the  joint will not feel "right". There may be pain, stiffness or weakness. Under extreme circumstances, inaccurate surgery can result in noticeable leg-length inequality, hip dislocation, or early failure of the replacement. Whilst there are traditional methods that surgeons use to ensure a perfect replacement operation, there may be a risk of "human error". The main advantage of the MAKO robotic surgery is that the risk of inaccurate surgery is minimised. Whilst this does not remove all of the potential risks of surgery, anticipated benefits include better patient recovery, level of functioning, and implant longevity.

How is it done?

A week or two before surgery, a CT scan is performed to accurately "map" each patients individual anatomy.  The surgeon then performs a "virtual operation" long before the real procedure. This allows the surgeon to select precisely the best implant position and orientation. Factors such as leg-length, offset, and implant fit can be adjusted to the millimetre as required. Precise pre-operative CT- based planning also provides very specific information to allow the Surgeon to select the most appropriate prosthetic design and implant size.

During the operation, the Mako robot guides the surgeon to  deliver precisely the operation as planned. If the tissues around the joint are abnormally contracted or lax, the Surgeon can make adjustments. The Mako robot will then be able to accurately gauge the effect of any subtle adjustments and feed this information back to the Surgeon.
