What are the benefits of robotic knee replacement?

According to data from the National Joint Registry, over 100,000 knee replacement procedures are performed annually in the UK. Typically, this represents approximately 89% of total knee replacements, 10% were partial knee replacements, and 1% were patellofemoral knee replacements.

Orthopaedic surgery techniques and technology have continually evolved over the decades, and it is believed that the most recent advances in robotic-assisted joint replacement have further improved patient safety and outcomes.

The Mako device does not replace the surgeon; the system’s robotic arm and state-of-the-art 3D software enable your knee surgeon to deliver greater precision and a bespoke procedure.

The first stage is the pre-surgery planning which is individualised for each patient. A CT scan of your knee is taken, from which a 3D virtual model of your joint is created. Neil will use this model to evaluate the degree of wear and tear, the alignment of your joint and the surrounding tissue and bone to determine the optimal placement and alignment of your new joint.

During surgery, constant real-time data is provided so your new joint can be assessed regarding movement and tension. Neil uses the robotic arm to remove precisely only the arthritic portions of bone and cartilage before the new implant is placed in the knee joint.

Robotic knee replacement benefits

Robotic-assisted surgery allows for greater precision, which means better joint alignment and less damage to healthy tissue. This results in smaller incisions and less scar tissue, reduced risk of infection and a faster recovery time. This superior precision means that there is less friction with the new joint, resulting in fewer complications in the future.

In a clinical study published in the Journal of Knee Surgery, Mako knee replacement patients that were surveyed six months after their operation reported lower pain scores than those who had undergone a conventional joint replacement. In the same study, they also reported better patient satisfaction scores.

What are the risks?

There is an increase in the operating time compared to traditional knee replacement surgery, but this is minimal. Robotic knee replacement has the same risks as conventional knee surgery, such as infection, ongoing pain and lack of function, or problems with the implant that requires further surgery, but it is hoped that robotic knee surgery will further reduce the chance of complications.
