In robotic total hip 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. Before hip robotic total hip replacement surgery, three-dimensional planning is made using the robotic system. Since the route and range of motion of the patient’s joint is determined by the robotic system, the implant is placed in the patient’s hip structure in the most appropriate and correct way.
Bone incision and carving processes are performed with the robotic arm.
WHY ROBOTIC HIP IMPLANT?
Advantages of Robotic Total Hip Replacement Surgery
- The risk of hip implant dislocation is reduced!!!!!
- Postoperative leg length differences are prevented!!!
- Incisions are made only on the parts of the hip bones, where incisions are need.
- Personal implant size and alignment, suitable for the patient’s structure, are ensured.
- Patient feels a more natural hip.
- 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 Hip Replacement Surgery
First of all, a 3D virtual model of the hip joint is created with the X-ray and CT scan images of the patient’s hip. In 3D modeling, the locations and dimensions of the bone incisions to be made on the hip are determined. Thus, soft tissue balance and the dimensions and location of the implant to be applied to the patient are exactly planned before the operation.

Robotic Total Hip Replacement Surgery
After completion of the necessary preparations of the patient in the operating room, the surgeon places the special apparatus used in the Robotic Prosthetic Surgery in the appropriate areas. Then, the robotic systems show the bone incision points in the digital environment, while also providing the surgeon with real-time information and visual data for the placement of the hip joint implant.

3D imaging of the placed total hip implant
During the surgery, the robotic system help evaluate the compatibility of the implants at all bending angles of the hip. 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 hip 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 Hip Replacement Surgery
Robotic surgery (MAKOplasty) can be performed on any patient who needs a total hip 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 and hip dislocations which are likely to cause problems in placing the implant parts in the ideal positions during manual hip replacement surgery.
