Robotic Orthopaedic Surgery

The Princess Grace Hospital is proud to be the first hospital in the UK to offer robotically assisted procedures for patients requiring a partial knee replacement due to osteoarthritis. This procedure is an innovative technique for orthopaedic surgery and is conducted using the RIO® robotic arm system. Since 2006, 50,000 procedures have been performed using this system and it has been found to produce consistent precision.

The robotically assisted procedure enables your surgeon to plan your surgery based on a CT scan of the area to be operated on. From this scan, a 3D virtual model is generated which is used to create a unique surgical plan based on your anatomy and this indicates the optimal size and placement of your implants. The high level of accuracy of implant placement achieved through this procedure is vital for correct biomechanical reconstruction.

Your personalised pre-operative plan is programmed into the robotic system, which guides your surgeon during the procedure and prevents movement outside of pre-defined boundaries. This guidance enables the surgeon to remove the diseased bone while preserving the surrounding healthy bone and tissue, which leads to a more natural feeling knee post-surgery. If necessary, the surgeon can alter the plan intraoperatively based on real-time auditory, visual and tactile feedback in order to achieve the best results for the patient.

Parital knee replacements using the MAKO system

Partial knee replacements are recommended over total knee replacements as they require a less invasive procedure. The benefits of using the MAKO robot for this procedure include a smaller incision, fewer complications, less pain and faster recovery times; restoring your confidence in your mobility and helping you to return to your active lifestyle within weeks. Another benefit of the procedure is that it probably increases the lifespan of your implants. Although the lifespan of implants is affected by many factors including a patient’s weight and activity level, the accuracy of placement during surgery also plays a vital role with optimal alignment and positioning increasing the life expectancy of your implants. Therefore, the enhanced accuracy of alignment and positioning achieved using the robotic system helps your implants to last longer, resulting in greater patient satisfaction.

Your consultant will advise you about your suitability for this treatment; however, the procedure is usually offered to patients displaying the following symptoms:

  • Knee pain with activity, on the inner knee, under the knee cap or the outer knee
  • Start-up knee pain for stiffness when activities are initiated from a sitting position
  • Failure to respond to non-surgical treatments or non-steroidal, anti-inflammatory medication
  • Early- to mid-stage osteoarthritis of the knee and damage localized to one or two knee compartments
  • Aren’t quite ready for a total-knee replacement and is looking for a less invasive knee surgery
  • Not bow-legged or knock-kneed more than 15 degrees

Total hip replacements using the MAKO system

These are available and recommended for patients who have osteoarthritis of the hip. The technique is being used in inflammatory and non-inflammatory arthritis and also in post-traumatic cases.

The CT scan guided planning and the RIO-MAKO assistance at the time of surgery leads to optimal placement of the implants and minimal leg-length differences post-surgery. This technique minimises the risks of leg-length inequality, of instability and of weakness after surgery. It should, therefore, afford the patient the opportunity to return to an active lifestyle earlier and more comprehensively.

Your consultant would be able to advise you about your suitability for this procedure, but it is generally undertaken with patients who are experiencing the following symptoms:

  • Pain when bearing weight on the affected hip
  • Limping in order to reduce the weight being put on the affected hip
  • Radiating pain to the groin, lower back or down the thigh to the knee
  • Pain or stiffness in the hip during walking or other physical activity
  • Failure to respond to non-surgical treatments or non-steroidal anti-inflammatory medication

Additionally, the system can be used for patients suffering with avascular necrosis or hip dysplasia.
