Why is the procedure performed?

A total knee replacement is considered for someone with debilitating knee pain and instability of the knee.

Indications for knee arthroplasty include the following:

• Progressive knee pain that prevents you from carrying out daily tasks
• Mild to severe knee pain that arises when sleeping or at rest
• Persistent knee inflammation and swelling over the knee cannot be relieved with medications or rest.
• Conservative treatment measures (prescribed medications, physical therapy and injections) fail to alleviate knee pain.
• A congenital knee deformity known as bow legs, or genu varum, occurs when the legs protrude at the knees, and the ankles and feet converge.

How do you perform total knee replacement?

A total knee replacement helps relieve knee pain, restores knee functionality and corrects the position of the knee. After administering general anaesthesia, Dr Vardi makes a cut over the skin of the knee in order to reveal the knee joint. Afterwards, he cuts into the affected parts of the femur bone at specific angles using specialised tools. Next, Dr Vardi connects the femoral piece to the bottom end of the femur, with or without using bone cement. He then shaves the damaged portion of the shinbone and the injured cartilage. By shaving away the damaged surfaces and bone spurs, Dr Vardi can create a smooth, gliding surface to which he can attach the new implants. The plastic insert, which enables the femur to glide over the tibia smoothly, can help stabilise your body's weight. Then, the tibia, femur and prosthetic pieces are constructed to form the knee joint.

What is robotic-assisted knee replacement surgery?

Robotic-assisted knee replacement is exactly the same as traditional knee replacement surgery; the only exception is that surgery is done using a robotic arm that allows for surgical precision.
