What is Robotic Surgery?
Robotic assisted joint replacement surgery utilises computer-assisted planning combined with a robotic arm guided by your surgeon, to improve precision and accuracy in joint replacement surgery.
The first step involves taking a CT scan of the affected joint. This CT is used to create a 3D computer based plan for the surgery.
During the surgery a computer, a sensor and a robotic arm are all present in the operating theatre. The computer based plan guides the surgeon, with real time feedback given on the accuracy and appropriateness of the plan by the sensors. The plan can then be adjusted, based on this feedback, prior to the execution of the bone cuts by the robotic arm, which is guided by the surgeon.
Why choose robotic assisted joint replacement surgery?
Joint replacements have been a successful treatment for arthritis for a number of decades. Over this time we have learnt that a number of factors are important in both the successful functioning and the longevity of joint replacements. One of the most important of these factors is the positioning of the prosthetic components. Adequate positioning of the components is essential to prevent instability, wear and loosening of the joint replacement.
Despite years of experience, countless studies have shown that we are not as accurate as we think we are in terms of positioning of the joint prothesis or precision of the bone cuts made prior to prosthesis insertion.
Robotic surgery, with its 3D pre operative planning, real time intra operative feedback and precision cutting via the robotic arm, has been shown to improve the precision and accuracy of both the bone cuts, and component positioning during joint replacement surgery.
In addition, studies have shown that Robotic joint replacement surgery results in
- Less post operative pain
- Less post operative blood loss
- Less bone loss during surgery
- Faster recovery
- Shorter hospital stay
- Improved precision and accuracy of bone cuts and prosthesis positioning
Specific to Mako robotic Total Knee Replacements (TKR), studies have shown:
- Improved early functional recovery
- Better flexion range at discharge
Specific to Mako robotic Total Hip replacements, studies have shown:
- Lower incidence of leg length discrepancy
- Enhanced acetabular component placement accuracy
- Reduced dislocation rate
- Highest Forgotten Joint Score reported in the literature for THR
Advanced technology, done locally.
Dr Gomez uses the advanced, cutting edge, Mako robotic technology to perform all his joint replacement procedures locally at the Hillcrest Hospital Rockhampton.
The process begins with a CT scan of the hip or knee.
This allows the joint to be visualised in 3 dimensions. Accurate preoperative planning is then undertaken to precisely size and position the prosthetic components to each patients unique and specific anatomy.
This preoperative planning allows Dr Gomez to correct any joint deformity or leg length discrepancy with precision and accuracy giving optimal patient results.
During the operation specific points are marked out on the patients bone so the robot and computer can match these to those planned on the CT. Before any bone is cut or any implants are inserted the robot and computer provide a specific plan of what will work best in terms of component size and position for this patient.
The surgeon checks, and can modify, this plan to ensure optimal component size and position.
Once the plan has been accepted, the robotic arm is then used to prepare the bone with precision and accuracy prior to the insertion of the prosthetic components.
