As technology continues to evolve, so do medical treatments. Patients may be skeptical and miss out on more advanced treatments because they don’t know much about the new technology. Today, I would like to talk to you about “customized” treatment options in total knee replacement. There is a more technical term for “customized” treatment: patient-matched. What is patient-matched total knee replacement? Simply put, it means that the surgeon uses computer-assisted preoperative planning based on preoperative images to create an individualized guide for the patient. Clinical steps: 1. The patient undergoes X-ray and CT examination of the knee joint area. 2, engineers through the patient’s image data, to create a three-dimensional model of the patient’s knee joint. 3, the doctor through the three-dimensional model to observe the joint morphology, the development of surgical plans. With the help of preoperative 3D planning software, combined with the computer reconstruction of the 3D model, the doctor can accurately determine the size of the prosthesis, which not only eliminates the need for repeated measurements and multiple adjustments during the operation, but also reduces the time and cost of transporting and sterilizing the instruments. According to the size of the prosthesis, the surgeon can determine the amount of bone that needs to be removed during the operation and generate the osteotomy guide in the software. With the osteotomy guide plate to guide the surgeon in the intraoperative osteotomy, it can ensure accurate osteotomy orientation and position, which can reduce tissue damage and improve the efficiency of the operation, especially in the presence of femoral deformity, it can reduce the amount of intraoperative blood loss and operation time, thus faster return to function and reduce pain. Patient benefits of Patient-Matched: shorter operative time, reduced risk of fat embolism, less intraoperative blood loss, better postoperative mobility, and faster recovery time. Patient-matched total knee arthroplasty has been gradually recognized and used by medical colleagues, and is expected to be widely used in clinical practice in the future. Patients with joint pain problems should pay more attention to this new technique, as it may be a possible way to further improve their surgical outcomes in the future.
