The following are the answers to the most frequently asked questions:
|Who can have the robotic artificial joint surgery?|
Most patients who can have general TKA and THA can have the robotic surgery.
Artificial joint surgery removes the damaged joint bone if the joint functions below capacity when it is injured or worn away due to degenerative arthritis, wounds, or other disease, and inserts an artificial joint (implant). If the joint functions below capacity because either the cartilage is damaged or worn away due to degenerative arthritis or injury, the surgery removes the damaged joint bone and inserts an artificial joint (implant).
This surgery is an outstanding treatment for patients who cannot have a non-operative treatment, but it obviously has limitations in that there is no treatment method for the next stage if the outcome is not desirable since it removes the bone.
It is also recommended to have a conservative treatment such as non-surgery or pain control making use of medical advice rather than to perform a surgery.
If surgery, the last stage of treatment, is the only option after a medical advice, more accurate robotic surgery is worth considering.
<Articular damage is accompanied by the following symptoms:>
· It is difficult to walk or go up and down the stairs because of the pain.
· It is difficult to bend or stretch your knees.
· Your legs are severely bow-legged.
· The knee is stiff or often swollen, or has a fever.
· The joint hurts and keeps you up at night.
· Physical treatment or medication is useless.
· It hurts even when you stay still.
|What is good about robotic artificial joint surgery?|
1. It provides personalized surgery to patients.
As each person has a different face, the shape of bone is also different. ROBODOC surgery robot shows the patient’s bone in 3D images, and the doctor can use those images for pre-planning of surgery personalized for the patient.

2. Accurate insertion of artificial joint (implant)
The accurate insertion of an artificial joint increases life expectancy of the artificial joint decreasing the ratio of reoperation.
It is important to select the personalized artificial joint that matches the bone shape accurately and cut the bone precisely to fit the selected artificial joint.
Robotic artificial joint surgery uses the computer program to calculate the size, position, angle, and direction of the artificial joint and the robot cuts the bone precisely as planned.

3. Reduction in possibility of reoperation
Robotic artificial joint surgery increases life expectancy of the artificial joint and reduces the possibility of reoperation with the accurate plan and surgery.

4. Minimization of bone cutting
The bones are not regenerated once they are cut off. Robotic artificial joint surgery reduces the unnecessary bone cutting and errors with the precise calculation and preserves as many bones of my body as possible.

5. Reduced side effects
Robotic artificial joint surgery reduces the side effects including inequality of limb length, pulmonary embolism, and fracture. The risk of infection is also reduced by using fewer instruments than in conventional surgery.

|Is robotic artificial joint surgery safe?|
Robotic artificial joint surgery system secured the safety by acquiring the medical device license of the US FDA, the European CE mark, and Korea’s MFDS.
The system also has two safety devices.
BMM (Bone Motion Monitor) monitors the patient’s movement.
When there is a movement, the robot detects it immediately and stops the motion instantly to pause cutting.
Force Sensor detects the force and pressure applied to the robot.
If excessive force is applied or a similar impact occurs to the robot during surgery, the system stops with a warning message and pauses the cutting.
|Do side effects decrease if I have robotic artificial joint surgery?|
Robotic artificial joint surgery reduces such side effects as inequality of limb length, pulmonary embolism, and fracture.
The risk of infection is also reduced by using fewer instruments than in conventional surgery.
|Where are the hospitals doing robotic artificial joint surgery?|
There are 18 hospitals that perform robotic surgery in Korea including four university hospitals and general hospitals.
Seoul: Dongjak Kyunghee Hospital, Sarang Plus Hospital, Leaders Hospital
Gyeonggi: Bagae Hospital (Pyeongtaek), LeeChunTek Hospital (Suwon), The Joeun Hospital (Wirye), Nanum Hospital (Namyangju)
Gangwon: Wonju Songji Hospital
Daejeon: S&K Hospital, Surgetop Hospital
Gwangju, Jeonnam: Chonnam National University Bitgoeul Hospital, Segyero Hospital, Sunhan Hospital
Gyeongnam: Seran General Hospital (Jinju), Gimhae Jungang Hospital, Mirae Hospital (Busan), Busan Centum Hospital (Busan), Centumhill Hospital (Yangsan)
|Is robotic artificial joint surgery possible even if I am old?|
If you can have general surgery and have no other risks in the operational process, robotic artificial joint surgery provides you with a safer surgery.
Because the robot cuts off your bones (milling type), it reduces side effects including fractures during surgery. Thus, it is safer for the elderly.
|Does robotic artificial joint surgery use only fixed artificial joints?|
CUREXO’s robotic artificial joint surgery system is open to use artificial joint.
It can support a new artificial joint based on open platform, and will have continued updates.
|I heard that MA (Mechanical Axis) during artificial joint surgery is important. What is it?|
Mechanical Axis refers to the alignment of the axis that connects the central line of the hip joint to the knee joint and ankle on a straight line.
If mechanical axis is well aligned, it distributes body weight evenly, hence there is no problem with the knee joint in supporting body weight. If the axis deviates from the straight line like varus and valgus, it is difficult to walk right aggravating the joint disease.
Thus, how accurately align the joint is important in artificial joint surgery due to joint disease.
CUREXO’s robotic artificial joint surgery can align the bones of lower limb accurately with more precise surgery.
The accurate alignment of bones can increase life expectancy of artificial joint surgery and decrease the ratio of reoperation, and also increase ROM (Range of motion).
