If the cartilage in the knee joint is completely worn out, the joints should be replaced with a number of materials that perform the tasks of the joint by acting like the joint. The placing of these materials is called knee replacement surgery. Robotic-assisted knee replacement surgery refers to the state-of-the-art system that helps to insert the prostheses in millimeters during knee replacement surgery. Let us talk about osteoarthritis of knee and manual knee replacement surgery before robotic knee replacement surgery.
Osteoarthritis of Knee
Osteoarthritis of the knee is a condition which is wear of the cartilage in the knee joint due to fraction. The most important two factors of this disease are age and excessive weight. The friction of the bones consisting of the joints causes wear of this area by time. Way of use ca expedite this process. One of the most important factors which speed up osteoarthritis is extra load on the knee joint carrying out the body due to excess weight. First aim osteoarthritis of knee treatment is to stop osteoarthritis with an intervention when osteoarthritis is at the beginning stage. Because it is impossible to rebuild a joint with osteoarthritis. When it is advanced, the only treatment method is knee replacement surgery.
Robotic Knee Replacement Surgery
The most important complaint caused by osteoarthritis of the knee is pain. The level of the pain is in proportion to the level of the disease. Rarely, pain increases as osteoarthritis increases. The pain that first occurs when walking and forcing the knee can become severe enough to wake the person from sleep by time. The pain can be accompanied by restriction of movement and inability of walking. If osteoarthritis of knee is advanced, pain is so severe that the patient cannot sleep at night, the patient has difficulty in walking, the life quality is significantly reduced, knee replacement surgery may be required.
Knee prosthesis means the materials which are attached instead of worn joint surfaces. These materials are compatible with the body and act just like the joint. It is performed with an open surgery method and takes 60 minutes on average.
Robotic-Assisted Knee Replacement Surgery
Robotic-assisted knee replacement surgery is one of the renovations provided to the health care sector thanks to developing technology. Due to its high cost, this technology, which is found in very few institutions in our country, ensures that all calculations performed manually are carried out in computer environment.
In knee replacement surgery, the place should be calculated after the cartilage is cleaned and before the prosthesis is placed. In classical knee replacement surgery, this calculation is made manually. Robotic knee replacement surgery calculates all angles in millimeter and risk of fault is eliminated. Prosthesis placed completely can be used for a longer time and comfort of the patient increases.
Before the surgery computed tomography (CT) of the knee joint is taken. Three-dimensional models of the knee are created with tomography. Created model is transferred to the robot (software). The software enables to place the prosthesis in the best way during the surgery. The robot gives the surgeon guidance for the correct preparation and placement of the prosthesis seat while providing visual and tactile notifications for the correct use of pre-calculated calculations. The operation is carried out by the surgeon, robot enables the surgeon to apply the measurements.
Even the most experienced orthopedic surgeon can be mistaken with manual measurement. However, the software kinematically evaluates the compatibility of the prosthesis with all the bending angles of the knee during surgery. In this way, the prosthesis placement process is performed with high accuracy and extremely sensitive to the patient’s own anatomy. Although the error is small, the prosthesis is less likely to cause problems, especially in later years. In particular, loosening complications are minimized and prosthesis life is maximized.
Advantages of Robotic Hip Replacement
- Lower risk of soft tissue injury.
- Shorter hospitalization.
- Faster recovery.
- Lower risk of complication.
- Longer prosthesis life.
