Over the last two decades, orthopaedic surgery has been revolutionised by advances in technology, vastly improving patient safety and outcomes. Robotic and computer-assisted procedures, such as knee replacement, are now widely practiced and very well established. In this illuminating article, renowned consultant orthopaedic surgeon Mr Ahmad Ali offers expert insight on the benefits of robotic assisted knee replacement surgery and explains how the future of orthopaedic surgery will be shaped by cutting-edge technology.



What are the most common orthopaedic surgical procedures which now involve robotics?


Computer-assisted surgery (CAS) has been developed and implemented into practice over the past twenty years. Knee replacement is the most common surgical procedure which can benefit from the use of the robotics to provide more precise and accurate alignment, therefore improving the patient’s outcome.


Robotic and computer-assisted surgery has many applications in knee replacement, including:

  • navigation knee replacement
  • personalised instruments for knee replacement
  • personalised implants for knee replacement
  • robot assisted knee replacement



Is robotic surgery safer or more accurate than open procedures?


Robotic surgery is more accurate than traditional surgeries due to the level of precision it offers which is beyond the natural ability of human eye. This allows for a better alignment of the leg and a better balance in the soft tissue around the knee.


Robotic-assisted surgery uses minimally-invasive incisions making the procedure safer as there is less tissue damage. This also results in less scarring, a lower risk of infection, shorter hospital stays and faster recovery. Overall, compared with traditional knee replacement surgery, robotic techniques have been shown to deliver better results, less trauma on the bone and surrounding tissue and improved outcomes for patients.



Are there any risks to robotic surgery?


Any surgery has risks but the robotic surgery has less risks than the traditional surgeries as it adopts the most minimally-invasive principles.



Does robotic surgery take longer than traditional surgery?


Robotic surgery requires a minimal increase in the operating time in order to adjust the computer sensors and probes. The benefits of this, however, far outweigh the disadvantages.



How is recovery impacted by the use of robotics in surgery?


The robotic surgery allows the patient to recover more quickly and get back to usual activities by restoring the pre-operative function faster than traditional surgeries. Minimally-invasive procedures mean there is less tissue damage than in traditional, open surgery, lowering the risk of infection and allowing for faster recovery.



What does the future of robotic surgery in orthopaedics look like?


The technology used in orthopaedic surgery is expected to continue to evolve in to cover more aspects of practice so that more patients can benefit from it. The robotic knee replacement is expected to become standard practice and the default for any future arthroplasty due to the advantages it offers.

Orthopaedic surgery

Mr Ahmad Ali is a highly-skilled and trained orthopaedic surgeon in the Essex area, specialising in knee procedures. His sub specialties include total knee replacement, repeat knee replacement, osteotomycomplex knee injuries (such as multiple ligament reconstruction), and sports injuries. He offers private surgery with Spire Hartswood Hospital, Spire London East Hospital, and Nuffield Health Brentwood Hospital. 

By using computer-navigated surgery, Mr Ali has not only stayed up to date with new technologies in medicine, but he has also embraced them to improve the outcome for his patients. This new technology helps enhance the accuracy of the replacement operation, the function of the new artificial joint, and increases its longevity.

Mr Ali studied at Oxford University and Sheffield University before furthering his training on the higher surgical-training programme at Health Education England's Northwest School of Surgery. During his studies, he trained in three different regions that exposed him to a broad range of complex orthopaedic conditions, experience, and insight. To expand his training, Mr Ali went to Canada during his training years to work in two major specialised units.

After working for a year as a fellow, Mr Ali started his specialist career with Barking, Havering, and Redbridge NHS Trust in 2003, working within their hospitals. Nearly 20 years later, he remains a highly-regarded consultant there, mainly with Queen's Hospital in Romford, Essex, and King George Hospitals in Goodmayes, Essex.

To add to his dedication in his specialty, Mr Ali helped found Essex Knee Group, a collective of specialist knee surgeons who meet regularly. The group of esteemed doctors share their patient outcomes and experience to advance their skills and benefit both the doctors and their patients.
