Knee Prosthesis

A total or partial knee prosthesis

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.

Material of the Knee Prosthesis

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.

Extremely precise placement

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.

How long does a knee prosthesis last?

The average lifespan of a knee prosthesis is between 15 and 20 years, depending on various factors such as the load placed on the prosthesis and the quality of the bone structure. The knee prostheses used by Cortoclinics have been extensively tested for durability. These studies show that a hip prosthesis functions well for at least 10 years (ODEP rating 10A).

Because these prostheses have already been on the market for many years (5 to 10 years) and are made from materials with a proven long lifespan, they are expected to last 15 to 20 years in practice. As the prostheses remain in use for longer, the rating may increase further, which would confirm their durability even more.

Frequently Asked Questions

A knee replacement is often necessary when conservative treatments, such as physical therapy and pain medications, do not provide sufficient relief for serious knee problems, such as osteoarthritis. Symptoms such as persistent pain, stiffness and reduced mobility can seriously affect your quality of life. When daily activities become difficult and pain persists, a knee replacement may be an effective solution to restore function.

A knee replacement is a major operation, but the severity varies from person to person. It requires anesthesia, making an incision in the knee and placing the prosthesis. Although the operation is complex, robot-assisted surgery (Mako) and the optimized care method of CortoClinics ensure faster recovery and fewer complications, which is why many clients experience good results.

Een knieprothese kan met behulp van robotondersteunde chirurgie worden geplaatst in gespecialiseerde klinieken en ziekenhuizen die deze technologie aanbieden, waaronder Cortoclinics. Robotica zorgt voor nauwkeurigheid tijdens de operatie, wat leidt tot betere uitkomsten en minder complicaties. Cortoclinics biedt deze geavanceerde behandelmethode en is als enige kliniek in Europa gespecialiseerd in knie- en heuporthopedie.

A knee replacement is an artificial joint that is implanted to replace a damaged or worn knee joint. This is usually done in people with severe knee osteoarthritis or other conditions that have severely damaged the knee.

With a total knee prosthesis, the upper leg and the lower leg portion of the knee are replaced, while with a partial knee prosthesis, only the inside, the outside or the portion behind the kneecap is replaced.

After knee replacement surgery, you will usually use crutches for 4 to 6 weeks, depending on your recovery and the recommendations of your doctor or physical therapist. In the first few weeks, crutches help to take the weight off your knee and provide stability. Over time, and with proper guidance, you can transition to a normal walking pattern.
