Mako robotic-arm assisted hip and knee surgery at Circle Bath Hospital

Get your knee or hip replaced with the latest robotic-arm assisted technology

The Stryker Mako robotic-arm system is a state-of-the-art technology that assists surgeons in hip and knee joint replacements. It has been described as the gold standardof hip and knee joint replacement.

This proven and trusted system provides several patient benefits over and above standard surgery, including:

  • A surgical procedure customised to the patients exact requirements – the Mako system develops a pre-op plan and guides and assists the surgeon during joint replacement surgery to ensure implants are placed in the optimum position
  • New levels of accuracy within the operation – the system allows fine adjustments as the surgeon requires to get the most accurate result
  • These factors lead to faster recovery time with less post-op pain

Circle Bath Hospital has performed over 100 robotic assisted knee and hip replacements, contributing to more than 100,000 total procedures performed with the Mako system around the world.

What is involved with robotic-arm assisted surgery?

Before surgery, the surgeon utilises the Mako technology to create a personalised surgical plan based on the unique requirements of the patient. First, a CT scan of the joint is taken, which is then uploaded into the Mako System software, creating a 3D model of the joint. The surgeon can then use this 3D model to plan the surgery and generate greater accuracy during the surgery itself.

During the surgery, the surgeon guides the robotic-arm within a pre-defined area, based on the original pre-op plan. With the system helping the surgeon stay within the planned boundaries, they can deliver a more accurate placement and alignment of the implant.

Whilst the technology is an important part of the overall procedure it is important to understand that the orthopaedic surgeon is in control of the surgery at all times, guiding the robotic-arm to position the implant in the joint. The Mako Robotic-Arm does not perform surgery, make decisions on its own, or move without the surgeon guiding it, the technology simply assists the surgeon in delivering a superior result.


What happens after surgery?

The recovery process varies for each patient, but this short overview should provide insight as to what can be expected in the days following the procedure.

Immediately after the surgery, and for the rest of your time in the hospital, your surgeon, nurses and physical therapist will closely monitor your condition and progress. As soon as possible your physical therapy will begin, with a lot of time being spent exercising the new joint as well as going through other exercises to help your body recover from surgery.

Over the days proceeding the surgery pain medication will be reduced, your mobility will improve and you will soon be back onto solid foods. Before leaving the hospital your physical therapist will talk you through rehabilitation exercises to be done at home and, depending on limitations in movement, an occupational therapist may provide direction on how to use devices to assist in daily tasks such as bathing and getting dressed.

Finally, your consultant and physiotherapist will discuss plans for returning home and ensure that you have all the necessary support to recover as quickly as possible.

Of course, support doesnt end when you leave the hospital, you will be given information on follow up appointments and contact details if you have any questions or struggles at home.
