Knee osteoarthritis can cause severe pain and make movement difficult. In such cases, a total or partial knee prosthesis can provide relief. This prosthesis replaces parts of the knee joint, allowing you to move smoothly and without pain. At Cortoclinics, knee prostheses are placed using advanced robotic arm technology for extra precision.
Partial Knee Prosthesis
A partial knee prosthesis replaces a part of the knee joint. This option is suitable if only one side of the knee shows wear. The prosthesis has two parts: an upper and a lower metal component. The lower part is covered with a layer of plastic, ensuring smooth joint movement.
Total Knee Prosthesis
A total knee prosthesis replaces the entire knee joint. This prosthesis comprises a metal upper and lower part, with a polyethylene plastic disc in between. Polyethylene is a highly durable material that can last a lifetime but is subject to wear. This disc ensures the artificial joint moves smoothly, restoring the knee’s mobility.
The total knee prosthesis is made of titanium. The plastic component is made of polyethylene. These materials are specially developed for medical use and are well-accepted by the body.
At Cortoclinics, we use Mako-assisted robotic arm technology for knee replacements. With 3D imaging and real-time feedback, the robotic arm assists the surgeon in accurately placing the implant according to your anatomy. This results in a better fit and alignment, faster recovery, and long-term satisfaction.
The surgeon programs the robotic arm with CT scan data and guides it during the surgery. The robotic arm removes no more bone than necessary, allowing the prosthesis to fit your knee perfectly.
The average lifespan of a knee prosthesis is between 15-20 years. The longevity depends on many factors, such as the load it bears and the quality of the bone structure.
The prostheses used by Cortoclinics have been tested for durability. These tests show that the partial knee prosthesis functions well for at least 5 years and the total knee prosthesis for at least 10 years (ODEP rating 5A and 10A). As prostheses remain on the market longer, their rating can increase.
Suppose a prosthesis eventually wears out or becomes loose. In that case, it is generally possible to replace it entirely or partially, known as a revision.
