Indications and contraindications after knee prosthesis implantation | Brasilia Web

One of the causes of knee osteoarthritis is excessive high-impact physical exercise for a long period. Over the years, former high-performance athletes and amateurs can suffer from pain, stiffness and difficulty in movement, due to the wear and tear of the cartilage that cushions the bones of the knee. In these cases, surgeries to implant a prosthesis, called arthroplasty, are safe and effective in relieving pain, providing an improvement in function and, consequently, in the patient’s quality of life.

However, practitioners of physical activities still have doubts about what can be practiced after arthroplasty. In general, low-impact exercises are allowed, but each case needs to be individually evaluated by the surgeon and the resumption must be done gradually, respecting the postoperative period indicated by the physician, and accompanied by physical therapists and physical educators. More than 90% of people who undergo the procedure experience a huge reduction in knee pain and a significant improvement in their ability to perform common everyday activities.

According to the American Academy of Orthopedic Surgeons (AAOS), realistic activities after total knee arthroplasty (TKA) include unlimited walking, swimming, golf, light hiking, biking, and dancing. salon, which present reduced risk of falls and sprains. Weight training is also possible, as long as it is guided by the surgeon and physiotherapist, so that the range of motion of the prosthesis is respected and there is no overload.

Studies show that most patients who participated in some regular physical activity before TKA returned to sports practice after surgery, with low impact sports being more common. The level of physical activity does not depend on pain and postoperative symptoms, but on the satisfaction with the surgery, motivation and the individuals’ functional capacity. Thus, the return to sport is not only possible, but recommended at recreational levels, and a collaborative patient, educated and with adequate physical conditioning preparation, can improve both in functional and cardiovascular and psychological levels, with increased self-esteem and quality of life.

Experts also point out that, with normal use and activity, knee prostheses show wear and tear on the plastic spacer. Excessive activity or excess weight can accelerate this natural wear and tear and cause the prosthesis to loosen and become painful. Therefore, many surgeons advise avoiding activities such as jogging, jogging, jumping, or other high-impact sports for the rest of your life after surgery.

Technology brings more precision and success to procedures
A successful knee surgery depends on the surgeon’s skill, the quality of the prosthesis, the hospital structure and the instruments used. With the advancement of technology, prostheses are increasingly efficient, providing comfort, safety and mobility to patients after implantation. On the other hand, robotic medicine started to help surgeons to have maximum precision in the procedures of total knee arthroplasty, enabling a faster recovery of the patient, as well as the return to the routine of daily activities in the postoperative period.

Among the premises of a successful arthroplasty is submillimeter precision in incisions for joint replacement. Newly arrived in the country, the ROSA® Knee System, a robot-assisted surgical system, has helped surgeons to optimize the efficiency of the planning and execution of surgeries. Developed by the American multinational Zimmer Biomet, the system provides continuous data analysis to assist in making complex decisions, allowing surgeons to use computer technology and software to position surgical instruments with great precision during procedures.

international recognition

The ROSA® Knee has just been recognized as the “Best Technology Solution in Orthopedics” by receiving the MedTech Breakthrough 2021 award. Annually, this independent market intelligence organization recognizes the most outstanding companies and solutions in healthcare, in global scope. The evaluated requirements are innovation, performance, ease of use, functionality, added value and impact.

About ROSA® Knee

The ROSA® Knee is a robot-assisted surgical system designed to assist surgeons in performing total knee replacement surgery, with features to assist with bone resections as well as assess soft tissue status to facilitate implant placement in the intraoperative period. The system provides continuous data analysis to aid complex decision-making and allows surgeons to use computer technology and software to position surgical instruments, enabling greater precision during procedures. The ROSA® Knee features the X-Atlas™ imaging protocol – which provides preoperative X-ray-based images to create a 3D model and plane of a patient’s bone anatomy – and real-time intraoperative mapping of the anatomy and motion of a patient. a patient, to help surgeons customize procedures and optimize implant placement.
