Knee replacement, also known as knee arthroplasty, is a surgical procedure that involves replacing damaged or worn out parts of the knee joint with artificial components. This procedure is typically performed on individuals who suffer from severe knee pain and stiffness, as well as reduced mobility due to conditions such as arthritis, injury, or other degenerative joint diseases.

Knee replacement surgery is a safe and effective option for many patients, offering a long-lasting solution to knee pain and other mobility issues. In this article, we will discuss what knee replacement surgery is, who it is suitable for, its advantages, how it is performed, and frequently asked questions about it.

Who is knee replacement surgery for?

Knee replacement surgery is typically recommended for patients who have not responded to non-surgical treatments, such as physical therapy, medication, or lifestyle changes.

Candidates for knee replacement may experience chronic knee pain, stiffness, and difficulty walking, standing, or performing everyday activities. Additionally, candidates may have a history of arthritis, injury, or other conditions that have caused significant damage to the knee joint.

Robotic knee replacement surgery can be performed on any patient who needs prosthetic surgery.

The Knee Replacement Procedure

Knee replacement surgery typically takes several hours and involves several steps. First, the damaged parts of the knee joint are removed, including the cartilage and bone. Next, the artificial components are carefully implanted, including the femoral component, tibial component, and patellar component. Once the components are in place, the knee is carefully tested for stability and range of motion. Finally, the incision is closed, and the patient is moved to a recovery room.

What is robotic knee replacement surgery?

Robotic knee replacement surgery is a surgical procedure where a robot assists the surgeon during prosthetic surgery. It helps the surgeon with the correct placement of the prosthesis at appropriate angles and avoiding mistakes in bone incisions. Contrary to popular belief, the surgeon performs the operation, not the robot. Before the operation, CT scans and special x-rays are loaded onto the robot, and a plan suitable for the patient’s anatomy is made.

What are the advantages of robotic knee replacement surgery?

The advantages of robotic knee replacement surgery are numerous. These include:

• Millimetric application of preoperative planning

• Elimination of human factor errors during surgery

• Precise cutting of the bone saw within the planned area

• Prevention of wrong and unnecessary incisions

How is robotic knee replacement surgery performed?

In robotic knee replacement surgery, preoperative CT scans and special x-rays are performed to examine the anatomical structure of the patient in 3D. These images are processed in a certain program and uploaded to the robot. The robot is covered with sterile covers during surgery to prevent infections. Two separate metallic implants are placed on the patient’s thigh and shinbone, allowing the robot to follow the position of the patient in space and the changes caused by the surgery. The robot is activated during bone cuts and loosening.

What are the prices of robotic knee replacement surgery?

The price of robotic knee replacement surgery may vary depending on the hospital’s price policy and the doctor’s price policy.

Risks

• Infection at the surgical site.

• Blood clots in the leg vein or lungs.

• Nerve damage, leading to numbness, tingling, or weakness.

• Prosthesis complications, such as loosening or dislocation.

• Continued pain or stiffness in the knee.

However, thanks to advanced robotic knee replacement surgery, these risks can be significantly reduced.

Before the procedure

• A thorough medical evaluation to ensure you’re healthy enough for the surgery.

• Medications may need to be adjusted or stopped.

• Physical therapy might be recommended to strengthen the muscles around the knee.

• Preparing your home for post-surgery recovery, including setting up securing handrails, and removing tripping hazards.

• Fasting for a certain period before the surgery.

How do I know if I need knee replacement surgery?

• Severe knee pain that hinders daily activities.

• Moderate to severe pain while resting, either day or night.

• Chronic knee inflammation and swelling that doesn’t improve with rest or medications.

• Knee deformity, such as bowing in or out.

• No significant improvement with other treatments like medications, physical therapy, or injections.

How long does a knee replacement last?

• Most modern knee replacements are expected to last more than 15 years. The longevity of the implant depends on various factors, including the patient’s activity level, weight, and overall health.
