Robotic surgery stands out in orthopedics as an innovation, especially for the placement of prostheses. It is a promising option for patients with knee and hip joint problems, including those with osteoarthritis, a common condition of degeneration of the knee joints that causes intense pain and limited movement, affecting quality of life.
This is a very prevalent disease in the world population. Data from the World Health Organization (WHO) indicate that 80% of people over 65 years of age are affected by the disease. In Brazil, according to the Ministry of Health, there are 15 million people.
Knee replacement surgery is often necessary to alleviate symptoms and restore mobility in patients with osteoarthritis. Traditionally, these surgeries were performed using manual techniques and guides, which require great experience and familiarity with the instruments on the part of surgeons in order to place the prosthesis in the correct position.
Good positioning of the prosthesis is an important factor for greater surgery durability, reduced risk of loosening, better function of the patient’s new joint and improved postoperative pain.
“The arrival of robotic surgery has brought a great evolution in this field, offering greater precision in the positioning of the prosthesis and consequently improving short and long-term results for patients with osteoarthritis treated with knee arthroplasty surgery (knee prosthesis) with the assistance of a robotic arm”, explains Dr. Guilherme Gracitelli, orthopedist and knee surgeon at Hospital São Luiz Itaim.
According to the specialist, robotic surgery in orthopedics is also an important ally in more complex cases that require a knee prosthesis, such as major deformities, patients with previous surgeries and fractures of the limb to be operated on.
Among the main benefits of the technique are:
1. Improved Accuracy: Robotic surgery uses advanced navigation and imaging systems that allow the surgeon to perform procedures with an unparalleled level of precision.
“This is particularly valuable for osteoarthritis patients, as precise surgery is critical to achieving the best results. In this technique, the positioning of the prosthesis is assisted by the robot, but the surgery is performed by the surgeon and his team”, explains the doctor at São Luiz Itaim.
2. Detailed surgical planning: Each knee affected by osteoarthritis is unique, and robotic surgery allows detailed pre- and intra-operative surgical planning, with radiographic and tomography images in order to personalize the procedure according to the patient’s specific anatomy.
“This means that the doctor has a greater understanding of the patient’s previous anatomy and the prosthesis can be placed more precisely”, highlights Dr. Guilherme Gracitelli.
3. Faster Recovery: With robotic surgery, the loosening of ligaments and balancing required in surgery is minimized and patients with osteoarthritis generally have a faster recovery and less postoperative pain.
4. Good long-term results: The benefits of robotic surgery extend over time, as patients with osteoarthritis tend to experience good durability of the prostheses and a significant improvement in quality of life.
The relatively new technique requires infrastructure and qualified staff to operate the robot. To perform this type of surgery, the doctor needs to be certified by the robot manufacturers, undergoing theoretical and practical training, until he is qualified to use this technology on patients.
In the south of São Paulo, Hospital São Luiz Itaim offers this service. The Rede D’Or unit has a robot ROSA® Knee System (room)for knee prosthesis implantation, in addition to all the necessary back-up structure to carry out the procedures, with a highly qualified and specialized team.
“Robotic knee replacement surgery represents a major evolution in orthopedics, offering a highly precise and personalized approach, with several benefits for patients. It is a subject little explored, which is why it is so important to disseminate information regarding this treatment option to patients”, concludes the orthopedist and knee surgeon.
