In robotic total knee replacement surgery, the operation is planned, the patient’s data are evaluated, and the operation is performed with the help of robotic systems under the control of the surgeon. The most important features of Robotic Surgery include that bone incisions on the knee joint planned to be made in the surgery are designed preoperatively in the computer environment, component positions are adjusted optimally, and bone incisions are made flawlessly with the help of a robotic arm. The entire procedure is performed by your physician.
It determines the joint kinematics of the person and calculates the placement of the prosthetic components in the most accurate way. During the surgery, the robotic arm guides the orthopedic surgeon to correctly align and place the implant into the bone.

WHY ROBOTIC TOTAL KNEE REPLACEMENT?
Advantages of Robotic Total Knee Replacement Surgery
• Incisions are made only on the parts of the knee bones, where incisions are need.
• Personal implant size and alignment, suitable for the patient’s structure, are ensured.
• Patient feels a more natural knee.
• Faster and more painless recovery is ensured.
• It is possible to return to daily life more quickly.
• High accuracy placement of the implant prolongs the durability.
Preoperative Preparation For Robotic Total Knee Replacement Surgery
First of all, a 3D virtual model of the knee joint is created with the X-ray and CT scan images of the patient’s knee. In 3D modeling, the locations and dimensions of the bone incisions to be made on the knee are determined. Then, the knee implants are placed into the bones in the virtual environment, and personalized implant sizes are determined for the patient. During the virtual movement of knee joint, soft tissue balance is provided.

Robotic Total Knee Replacement Surgery
After the knee joint is exposed by the surgeon, certain points of the knee joint bones are marked, and the anatomy of the knee joint is revealed. Once the knee anatomy is revealed, it is compared with the result of the preoperative planning.

Identifying and marking the points on femur bone (thighbone)
It ensures a review of the soft tissue balance that is one of the important factors affecting the success of a total knee replacement surgery. Afterwards, if the surgeon finds the total knee replacement suitable for the patient in all respects, he or she makes the bone incisions. Bone incisions are made with the help of the robotic arm, under the control of the surgeon, and to the extent determined by the robotic system. In this way, unnecessary or inadequate bone incisions are prevented. In addition, vascular and neural structures are preserved. When the surgeon finds the placement, alignment, and ligament balance appropriate, he or she then places the original implant. As a result of the entire surgical procedure, the total knee replacement is performed with implants suitable for the patient’s anatomy, ensuring high precision, high accuracy, and a margin of error limited to 1 millimeter and 1 degree.

Patients suitable for Robotic Total Knee Replacement Surgery
Robotic surgery (MAKOplasty) can be performed on any patient who needs a total knee replacement. It is preferred because it allows for patient-specific planning and surgery. Another patient group consists of those with congenital or acquired (fractures, etc) bone curvatures which are likely to cause problems in placing the implant parts in the ideal positions during manual implant surgery.
