3D printing technology has revolutionised the industrial world in the past decade, and we can now use the 3D-printing technology in knee replacement surgery. Patients undergoing knee replacements using this technique will undergo a pre-op MRI scan of the lower limb – all the important data of the lower limb will be captured, and the alignment and the size of the implants will be pre-determined. These Patient Specific Instruments (PSI) will then be produced via 3D printers and subsequently sterilized, they will fit onto the patients’ knee joint anatomy perfectly and allow the surgeons to perform the knee replacements quickly and accurately.
Robotic surgery is the new dimension in the future of surgery, makoplasty is a semi-automated robotic arm that will assist the surgeon in performing the total knee replacement surgery. Patients undergoing knee replacement using this technique will undergo a pre-op ct scan of the lower limb, all the important parameters in the lower limb are then captured and entered into the computer. These data will then merged with the real-life anatomical landmarks of the patient on the surgical table, and the surgeon can use this robotic arm to perform the knee replacement to pinpoint accuracy. There is a safety mechanism built into the robotic arm as well to minimize the risk of nerve or blood vessels injury.
Overall, these advanced technologies have greatly improved the accuracy and the surgical results of the total knee replacement surgery/ partial knee replacements in Singapore. And computer navigations/ PSI/ Makoplasty will be the recommended techniques in patients who had a previous injury to the same lower limb resulting in a deformed anatomy or patients who have variant anatomy such as severely bowing of femurs.
There are other benefits such as reduced blood loss, reduced risk of embolic events as well, mainly related to the avoidance of instrumentation of the medullary cavity of the bone used by the traditional techniques.
