How is Robotic Prosthetic Surgery Performed?

Robotic Prosthetic Surgery (MAKOplasty) provides each patient with special planning and surgery. Patient planning should be made a few days before surgery. X-ray and CT scan images are uploaded into the system, and the planning is started. Using the pre-operative X-ray images of the patient, a 3D model of the joint is created with the system specially developed for this purpose (Figure 1-2). The physician mathematically determines the bone incision and implant sizes suitable for the patient, by analyzing the knee or hip model of the patient. Surgical planning can be made down to the smallest detail of the operation. The resultant plan is checked again during the operation.

The planned surgical operation is performed by the surgeon with the help of the robotic system. During the operation, the surgeon checks the preoperative plan and makes the bone incisions accordingly with the help of a robotic arm. In this way, a zero-error operation can be performed. On the computer screen, the surgeon can see the 3D image of the bone incisions made in the operation area with the help of the robotic arm (Figure 2). When making bone incisions, the robotic arm prevents possible errors or operations that may damage other tissues. It can be said that the possible margin of error is limited to 1 millimeter and 1 degree in robotic surgery. Robotic surgery also reduces the risk of embolism by eliminating the necessity to open channels into the bone during knee replacement surgery. Surgical treatment is completed optimally, under the control of both the surgeons and the robotic arm.
