Himchan Hospital Breaks 400 Partial Alteration of Robots"High Accuracy and Less Bleeding"
Aug 02, 2024
Himchan Hospital announced that as of the end of July, it had exceeded 400 cases of partial replacement of robotic knee artificial joints (hereinafter referred to as partial replacement of robots).
Partial replacement of the knee artificial joint is a representative treatment that can be performed when the cartilage inside the knee is partially damaged, along with orthodontic osteotomy. For Koreans who live a sedentary life sitting or squatting on the floor, only the inner cartilage of the knee is worn out, and the legs are often bent in an O shape. Orthodontic osteotomy is a treatment that relieves pain and slows arthritis by correcting the bent leg straight and dispersing the burden on the inner joint outward. However, since the area that causes pain is not cut, pain may remain after surgery, and there is an inconvenience of having to wear an aid or use crutches for about a month and a half.
On the other hand, partial replacement surgery cuts the damaged knee joint and replaces it with an artificial joint, so it has a great effect on relieving pain after surgery and is quick to walk and rehabilitate. Despite these advantages, the difficulty of surgery has been high, so it has not been performed universally in Korea. In the case of partial replacement surgery, it is difficult to secure visibility due to the small incision during surgery, making it difficult to balance the insertion position, angle, and ligament of the artificial joint. Recently, these limitations are gradually being supplemented through robotic surgery.
Robot partial replacement surgery increases accuracy by inserting artificial joints and balancing ligaments by looking at figures calculated by computer programs, not by the naked eye. In addition, since only about two-fifths of the joints are changed to artificial joints and normal joints are saved as much as possible, the function of bending and stretching after surgery is much more natural, so patient satisfaction is high.
In fact, the Institute of Arthology at Himchan Hospital compared partial replacement with general partial replacement, and found that partial replacement of robots increased surgical accuracy and reduced bleeding compared to general partial replacement. As a result of comparing 20 cases of external load tests that measure the gap between the inner joints (JLCA) with X-rays according to the external force (Valgus stress) pushed from the outside of the knee while the patient was standing, the partial replacement of the robot was 2.1 degrees and the general partial replacement was 3.4 degrees. When force is applied to the outside of the knee, the smaller the angle of the gap between the inner joints, the more stable it is.
In addition, the amount of bleeding was also found to be less in partial replacement of the robot. The amount of bleeding is the sum of the amount of bleeding measured in the operating room and the amount of hemobac (blood bag) bleeding measured in the hospital room, and 200 cases were compared with 216.3ml for robotic surgery and 320.7ml for general surgery, 104.4ml less for robotic surgery. The robotic surgery reduced the amount of bleeding by about 33%.
Increasing the accuracy of the operation in this way can reduce the amount of bleeding during and after surgery, and reducing bleeding can reduce the risk of complications or side effects that may occur after surgery.
Lee Soo-chan, CEO of Himchan Hospital (Orthopedic surgeon), said "Robot surgery also requires a lot of clinical experience from a surgeon. This is because surgery time can be shortened depending on the doctor's skill level. Shortening the operation time is also an important variable that can reduce the amount of bleeding. However, partial replacement surgery is essential because it can only be considered if the inside of the knee cartilage is damaged, the function of the cruciate ligament is normal, and there is no pain in the outer area, and the O-shaped leg deformation is within 10 degrees.'
